finally got the truck running but will not run if you let off the gas it stalls out any ideas? other thing is none of the gages work fuel gage temp oil p[ressure of charge or dash lights any ideas? is it possible we burned up[ the cluster? anything to look for?

 

got the dash lights working ( added a ground wire from the neg cable to body) but still have no gages any ideas?

 

Engine no idle but runs fine at higher RPMs in a truck already plagued with electrical problems could possibly be the idle fuel cut solenoid. Can also be any number of vacuum leaks, EGR valve, AAP diaphragm as well as a number of other things.

Personally I'd start with the idle cut solenoid. First thing you can try is to listen if it click when you turn the key on. If it doesn't, try permenantly jumping it open to your battery and see if it idles then. If it does you can either install a switch on your dash, or try to find the wiring fault from the fuse panel (I think it runs off the 15 amp fuse designated "Engine" in the fuse panel but again I might be wrong).

 

okay got the gauges working loose wire in the fuse box and a bad ground on some other wires the vacuum advance was not working got that sorted out and truck runs like a dream expect we now have a no charge issue no charge light on (does not come on even with key on) new altantor and voltage reg all wiress check out but it is not charging

 

Did you make sure the alternator has a ground to the engine?

 

okay i ground the alterantor to the engine and the body still no charge we changed outt eh voltage regs and same thing tookt eh altanter and had it tested and it tested fine 14.5 volts. the charge light did not work swaped out the charge lamp relay now the charge light and the brake warning lamp stay on

 

well guys we got it fixed i was looking at another post turns out the autopart store gave us the alt for the 6 wire external regulator where ours was a 5 wire took ti back and got the right all alt. and now it charges. the charge light doesn't work (wouldn;t go out tried another lamp relay then it wouldn;t come on but it read 14.5 volts at the battery so i think we are good for now!. funy part was the alt we had had a green plug on ti and the wires still plugged into it
