You'll find ten shops that can fix TBI before you find one that can properly and completely rebuild a carburetor and repair a worn-out centrifugal advance distributor any more.

Try finding a guy who knows how shoe a horse (yes, I know one who does and he happens to own and operate a machine shop).

They don't hold horse races at the local fairgrounds much anymore, either.

Not criticizing, just sayin'. It's a sign of the times.

Sorry to hear about your frustrations, but we'll try to help you iron them out.

I've had several of these trucks, one of them was the worst vehicle I'd ever owned. It stranded me more times than I could count, spent more hours and money fixing it than I ever wanted to, and lots of my problems stemmed from junk replacement parts that didn't have good longevity to begin with, or caused other more expensive failures.

I'm still here buying these things for some reason. Mostly because I know most of their flaws (after years of struggles) and often know exactly what to fix when they give me symptoms.

We'll try to help. Keep at it! :waytogo:

I agree with that I can't seem to do either one.

Thank you. I really appreciate the forum and letting me vent a little.

Got my truck back from local shop he said everything looked good, he drove it about 20 miles with no issues. He said fuel pressure should be 10-13 PSI mine was at 11 PSI under a load. One question I do have regarding grounds as I said before I changed the one from the frame to the firewall but the other one is on the back of the engine and is a ***** to get at and it goes to the firewall as well. Is there anything wrong with just finding another location on the engine that I can get to easily and ground that to the firewall? Any suggestions on where? I'm also going to clean the battery ground that goes to the fender and I think there is another one that goes to the thermostat housing. Thanks again for the help.

On my 1998 the engine ground strap goes to the frame, passenger’s side. The firewall ground strap attaches to the frame at the same spot.

Any 5/16” or 3/8” bolt hole that’s unused would make a suitable ground strap attachment on the engine.

However, other grounds used for ECU sensors (TPS, etc.) should be maintained in their original location (to the extent possible).

Sounds good appreciate the advice. Yeah mine for whatever reason goes from the engine to firewall and the other one frame to firewall. Thanks again for the advice

Yeah, that subtle detail may have been due to the assembly process and nothing electrical.
Yeah that's kinda what I was thinking too. I just got done running it from the mechanical fuel pump cover to the firewall. Cleaned the neg battery terminals, one on the fender and the other on the engine and the one on the thermostat housing. Cleaned them off put a good amount of dielectric grease on everything. Battery terminals are clean I don't know we will see.
