Title: 1994 GMC Jimmy - The RHSC
Post by: rentedmule on February 09, 2017, 04:08:48 PM
The red headed step child needs a 'resto' thread

It has the 4.3 CPI with ~224K kms on it. So far I've put a windshield in it, new headlights, fixed the y-pipe (and manifold studs), repaired hacked fixes on the front brakes (they left a nail in the flex line...) and a fuel line, replaced the shoes in the rear and parking brake cables, pitman and idler arms, swaybar endlink bushings, and a DS motor mount. I'll add some more pics when I get a chance.

Question for you folks - when the tranny is in park the wheels still roll freely. It's almost like park doesn't engage. All other gears work fine. Any thoughts?

Nice first gen !!

As far as the trans it probably has a broken parking pawl.  Some one jammed it in park when rolling.

That is much more red than the night shot made me think. RHSC it is!  Quite the progress so far and looks like you have a crack free dash? Always a good score on that.

I wonder how extensive the parking pawl fix is, maybe I'll look into it.

I've been driving it for a few days now and it's working great. The starter is still a bit loud and the wipers are super slow until the truck gets warmed up but otherwise all is well. We've had a pile of snow over the last week and are supposed to get another 18" or so tomorrow - the 4wd is nice.

I think it's the same red as my old '93

Ha! That's almost the exact same truck I had as my first car. Bright red long bed. It was a '91, but not too much changed in those 2 years.

This is why I wanted a 4wd:

We've had well over 3 feet of snow in 3 days. The first pic I posted of the truck in front of the barn was taken 1 week ago   :(

Oh damn I am glad to live in the south.  LOL

Loving your RHSC I have one as well but a 02 ext cab,I will be making a thread soon.

It's so variable - we've had spring-warm weather for the past week and 95% of that snow is gone. Now I need the 4WD because the driveway is a soupy mess!

Updates: In the process of tracking down an electrical gremlin, I (meaning the shop) fixed a few other issues.

It had a random starter on it that didn't fit properly, hence the noise and occasional sticking. Replaced that and it's quiet and works like a charm now.

The possible parking pawl issue ended up being something with a rod on the shift linkage that had popped out of place. Works great now and goes into park as it should.

Both the coil and ignition module were arcing and partially burned and distributor rotor was basically MIA - sort of shocked it ran as well as it did before. Replaced all of that along with a new dist. cap and it's running as smooth/quiet as new now.

Some combination of those new parts/fixes also made the trans shifts 100% better. It used to slam into every gear and push against the brakes a bit at stop lights (my '93 did that as well...) and it doesn't do any of that anymore.

On the down-side, my wipers stopped working on a 50 mile slushy highway drive this morning so I had to Ace Ventura it... Probably just something not plugged in tight on reassembly but I haven't had a chance to look into it yet.

so I had to Ace Ventura it...

Pure class hahaha

Love getting all those little things working and it feels like a new truck again.  I need to give the Long Bed a once over again to try and clear up my own set of mystery gremlins.

Dug around under the hood yesterday - the wiper motor mounting bolt that doubles a ground was loose. Cleaned it, tightened it, and the wipers work again!

I also found all 4 screws holding the cowl panel were missing and nearly every easily accessible screw on the dash was loose/gone. It's a much quieter place to spend time now!

Changed the PCV valve since it was easy. Tried to put on my new washer reservoir cap from Rockauto (old one is in pieces) and it was too small  :(

I'm really starting to hate this POS.

I'm also really starting to wonder how it actually ran...
Title: Re: 1994 GMC Jimmy - The RHSC
Post by: Harley on April 27, 2017, 06:50:19 AM
Did the compression blow that out of the cylinder or did you actually try to remove it?

WOW.  :o
Title: Re: 1994 GMC Jimmy - The RHSC
Post by: rentedmule on April 27, 2017, 07:22:26 AM
I tried to remove it and it just slide out as soon as I put the plug socket on it. I was going to swap them anyway but I wanted to read that plug to see if a leaky FP reg was dumping fuel into that cylinder. I worked at it with an easy out for an hour last night before giving up and just letting it soak in penetrating oil. At least access through the wheel well is good.
Title: Re: 1994 GMC Jimmy - The RHSC
Post by: Harley on April 27, 2017, 11:59:33 AM
I blew the porcelain out of a plug on my 2.8, but I'm pretty sure that was a manufacturing fluke rather than rust like that. Driving on 5 cylinders was interesting, but easy enough to fix at a friends house with the tools I had in the truck.

THAT is a whole different situation. Worst case a spark plug tap and a magnet reach tool to get all the debris out can't be too costly. How are the other plugs? I imagine the Stepchild will be much better behaved once you get those swapped.
Title: Re: 1994 GMC Jimmy - The RHSC
Post by: rentedmule on April 28, 2017, 05:38:20 AM
I'm thinking of renaming it the clustertruck.

I did get it eventually with an easy-out, 2 feet of socket extensions to get out the wheel well past fender, one broken tap handle, and a very large adjustable wrench. The biggest PITA was just finding something to adapt the easy-out to something I get leverage on - I was surprised that the adjustable wrench held tight enough as I really had to lean on it.

I didn't test my luck on the other 5 plugs yet but I soaked them all in seafoam deep-creep for a future project/frustration. This would have been much more difficult on a 2wd where plug access through the wheel well isn't as good.

I'm going to pull the intake manifold and change the FP regulator and maybe the lines before I attempt the other plugs.

I also swapped the broken rear hatch handle last night, which is only a 10 minute job if anyone is curious.

Started the FP regulator fix a few nights ago after the baby went to bed. This is after a pile of cleaning - you can see how clean the passenger side is from the leaking regulator. The upper is thick with black crude and soaking in degreaser at the moment:

When I did this on my '03 a few years ago it was absolutely spotless inside - the lack of EGR and the methanol injection I ran while boosted must have kept the crude off it

FYI: pulling the manifold on a CPI is so much easier than on the newer 4.3's, it only took 10 or 15 minutes to get it to this point. I have a new set of return lines that I picked up cheap in the classifieds, so I may swap those while I'm in there if it's not a PITA.
Title: Re: 1994 GMC Jimmy - The RHSC
Post by: rentedmule on June 03, 2017, 06:53:37 AM
Got it cleaned up and back together last night. Didn't end up changing the return lines but the old ones seemed fine anyway. It ran rough for the first 10 minutes or so, probably because of all of the crude loosened up in the manifold and the cleaner residue on everything but after it warmed up it ran like a champ. Solid idle, no stink of gas in the cab like before, and strong (for what it is) acceleration.

Next up is a power window motor for the rear door and the other 5 spark plugs.

Post by: rentedmule on June 23, 2017, 06:22:49 AM
Scrap that last line - next up was a new fuel pump / sending unit. The line coming out of the pump rotted and was pumping gas onto the top of the tank at an alarming rate. It finally doesn't stink like fuel anymore!

It feels good to get these old clunkers fixed up.

It felt great for the 7 hours it ran... then the starter died.  ::)

LOL  Sounds like my sons 2002 S10 its a Fla truck so its not rusty but at 240,000 miles everything that can does break.

I really want to love this thing but it's not making it easy! When it does run, it's quiet, comfortable, easily fits my mountain bike in the back, has a sweet tape deck (I only have a Platinum Blonde and a Midnight Oil cassette so far so I'll have to build my collection a bit), and is super easy to drive/park. Some day it will be reliable!
Title: Re: 1994 GMC Jimmy - The RHSC
Post by: Harley on June 25, 2017, 11:58:41 AM
What you need is a tape to aux cable adapter. At that point there is nothing you can hate about this truck.
Title: Re: 1994 GMC Jimmy - The RHSC
Post by: rentedmule on July 07, 2017, 09:21:52 AM
The cassette deck was a major selling point!  8)

Replaced the other 5 spark plugs and they all came out easy, no extractors or cursing required. The idle is still a bit rough and the only thing that hasn't been changed on the ignition side is plug wires. I have some extras on my turbo motor that I may swap on. I'm also going to sea foam it down the intake and see if that helps, the upper intake was pretty cruddy when I changed the FP reg so the valves probably look similar. It runs fine under load so I'm not really worried about it either way.

I raided the junkyard and found a solid '93 Jimmy donor truck. I pulled the rear bumper (mine's rotten), a class 3 hidden hitch, outside spare tire carrier, full set of OEM fender flares (only needed 2 but grabbed the lot), driver's visor (material has separated on mine), center console (lid hinge broken on mine), front hood seal (mine is all warped), wiper reservoir cap (mine was split), and a few interior switches.

Need to find a non-photobucket host for pics but will get them up eventually.

Lots of great goodies there. I'm glad the other 5 plugs came out with 0 issues.

ah yes the great photobucket crisis... Flickr has served me well. I've actually had their paid premium account for several years, but it's only a few bucks/year unlike photobucket's idea of a subscription cost haha

A few updates but nothing major - 'new' all season tires are on and I've started sealing up holes in the rear wheel-wells as a temporary measure for the winter (I'll replace them eventually).

I was getting a code 46 and it has been down on power for quite a while. I bought a new knock sensor and fought for hours trying to get the old one out of the block. After tearing off the 'nut' part of it I eventually gave up and plugged the harness back in to the main body of the sensor, which was still mostly intact. When I started it up the engine light was off and it's running perfectly...

Post by: rentedmule on November 19, 2017, 01:18:46 PM
I guess it wasn't so easy after all - problem returned (it was a code 43, not 46) so I had to drill out the sensor and use an extractor to get it out of the block. New sensor didn't fix the problem so I went hunting shorts again and found this:

Wire was broken right at the connector. Soldered on a new one and all is well; SES light is off and it runs great.

At least you know it's fixed now. Any snow up there yet? Had a light dusting around the workshop this morning.

No snow yet but the temperatures are right for it. I also fixed my rear defroster so it's pretty much ready for it now

Exhaust rotted off so I put on a Dynomax superturbo (2.5" mandrel bent) catback. It actually feels like it may now have some portion of it's original 200 hp back again!

Red Jimmy the snow-touring project is still alive. It hasn't broken down since the spring when I snapped a front lower control arm (that was fun) so I decided I would splurge. I bought a new set of decent all terrain (snow rated) tires (stock 235/75s) and put one of the leaf plies from the sonoma in to fix the saggy ass. It's not evident from the picture angle but I'm guessing it lifted the rear 1.5 or 2". It was enough that I had to adjust my seat back when I got in!

I painted the belt-line trim a while back too, it had turned grey and looked like crap.

It still has a small exhaust leak which I'm hoping is just at the Y pipe and not the manifold. The wipers are truly intermittent when it's cold out too, which makes for some interesting Ace Ventura driving moments.
