Asked by Derek Jan 08, 2013 at 07:42 PM about the 1995 Chevrolet C/K 1500 Ext. Cab 6.5-ft. Bed 2WD

Question type: Maintenance & Repair

i went to jump start one of my other vehicles with my truck and after i popped the hood on my truck and went to my other vehicle my truck started dropping in rpms and it jumped back up to normal for a second and kept doing that and the rpm drop kept getting lower until it was too low to continue to run and shut off.

Was the truck cold? I would bet it was the idle air controller.

It could be a fuel problem id check your fuel pressure first. But I had the same problem with my Camaro and it turned out it was the throttle position sensor. Took about a minute to replace and was only $20. Hope that helps.

Try pulling codes, none of the local parts stores will have the scanner for it since its obd 1 but there is a trick involving a paperclip and having you look it up is better than trying to explain it. Google GM obd 1 paperclip. If there is no codes then its a possibility its a fuel pressure issue. Sounds like there is a chance the pump is overheating then overloading or even the filter is in the first stages of getting clogged.

could possibly be an alternator problem its not charging properly all the time

how do you check the fuel pressure on these trucks

If its the 5.7 it's most likely an adapter between the fuel filter and the line for the fitting

your truck is still tbi injected if it is 95, there is no port to check fuel pressure on those. you have to remove the fuel filter, then a professional commercial duty fuel pressure tester kit comes with an adapter(3 way) that connects the two lines together with the filter removed and then the fuel pressure tester attaches to that 3 way fitting. fuel pressure on those setups in only 12psi

should state that is for 5.7 or 7.4 tbi injection, if your truck is a v6, then it has a vortec 4.3 and has a fuel pressure test fitting on top the intake, just follow the lines, and fuel pressure on that is 65psi
