I have a C10 pickup (1985) that has been giving me problems and they now seem to be coming to a head. definitely electrical in nature. i was thinking that this was a straight-forward cap/rotor or some other issue but now I am leaning to a short somewhere in the electrical harness. The symptoms:
- First it just wouldn't start for me a couple of times after I had driven it a little bit then cut it off.
- Then after replacing or testing nearly all of the engine electricals the problem persisted and got worse. I couldn't even get it to start in the mornings although it would crank.
- Now it won't even crank. Battery = good, starter = good, Ignition switch = good. I did find what appeared to be a short between the switch and the starter. I got zero volts when I cranked. But when I bypassed this and got 10 volts at the starter I was only able to get the truck to start once. Most of the time it is still dead. Is there something simpler that I am missing a relay perhaps? What is the most efficient way to go and test for shorts? Any help whatsoever would be greatly appreciated.
