1996 Chevrolet C1500 - Answered Questions & Fixed issues
"gear grinding" noise on acceleration, 2 wheel high only
This sounds like the famous problem that those ten bolts give, remove the rear differential cover and inspect the oil for metal debris, it's more than likely to be the carrier bearings wornout making the ring and pinion offmesh causing the grinding and will eventually break. Hope this helps
I have a 1996 Chevy silverado that will not start
In the first part of your post, are you saying, you have to jump starter relay in order to get it to start? I looked at info for 96 c1500, 5.0L engine. If I understand you correctly, check the control side of relay, left side in the diagram. It needs voltage and ground both. Ground is a chassis ground, voltage comes from crank position of ignition switch and is wired through the clutch or neutral switch, depending on the tranny.
How to chck a fuel pump
check 12V at pump terminal when on/cranking
hear/feel pump operation (if external to tank)
if low pressure (carby) disconnect fuel line and observe flow. If high pressure (FI) connect fuel pressure guage and observe pressure. Check fuel filter while doing all this. Filters are the source of many problems that start people messing with fuel pumps.
How to set the timing?
YOu should be able to time it somewhat without unplugging anything and if you get it close the computer will see that it stays when it is running.
How to test fuel pump
Use a multimeter at the plug to pump! If there is no power, check the fuses under the dash, as well as the fuse box under the hood! The lid under the hood will tell you which fuse operates the fuel system. Could just be a bad fuse, or a broken wire!
Cant find the second flasher relay
is it just the inside lights on the dash not working. it may just be the bulb/s they can both go at the same time. also the second relay is on top of the steering column a bit of a pain to get to. think you can get to it with the dash out..
