1991 Chevrolet Truck Repair Question
Did check primary voltage at the coil, pink wire, goes hot with the key on. Any voltage? Any applicable trouble codes? The pick-up coil sends a signal through the ignition module to the computer, without that signal, no spark or injector pulse.
I replaced coil already. Do not know how to check for pulse. This problem is wierd. All of the sudden it will start and run for 2 to 5 weeks, then just not start.
I am going to check for codes now
Did you check for voltage on the pink wire, key on. Which coil did you replace? I don't believe you can replace pickup coil with removing distributor?
I just checked for codes. There were no codes thrown.
Can you answer my questions about the pick-up coil and pink wire?
I replaced the coil that is outside of distributer. Where the coil wire goes.
How about the pink, use a voltmeter, should be hot/voltage with the key on.
I dont have voltmeter. I have TBI with 2 injectors. one injector has a red and blue wire and the other injector has a green and white wire. I used a simple test light and checked the red wire and it lit up with the ingnition turned on.
You said you have no spark. Without at least a voltmeter or testlite, it's hard to do any testing.
