I have a 1995 jimmy with around 150,000 miles on it. It will crank but not start. The coil is not getting fire to it. I have replaced the coil and the ignition module, with no luck. What else can it be? I can not get it started to bring it anywhere to get tested. Could it be the crank sensor or the cam sensor?

Hi, did you check for primary voltage at the coil? Pink wire goes hot when you turn on the key, use a testlite, anything? If your fully obd1 compliant, are there any trouble codes?

On the white wire at coil, there should be a tach signal, engine cranking.

Hello,

Look on the firewall about center way for the following

It is called an ESC Electronic Spark Controller. If you have this part your will need to have it looked up under a 94 jimmy.
