Got a 1987 chevy suburban and it wont start and it is getting fuel and cranking over


Check for vacuum leaks and for spark. The most common problem Ive seen is the ignition control module. Those are notorious on the older chevys. It is located on the bottom of the distributor.

My 1987 Chevy r10 cranks but wont start. i was driving and it just shut off like you switched the key off. i have no spark and injectors don't energize as well.


It is most likely the ignition module,have it tested,if it test good,replace the pick up coil in the distributor,this pulses the injectors.

1987 corvette cranks but wont start has fuel psi [50]and has spark.


The ignition module located inside of the distributor is what generates the signal that the ECM (Engine Control Module) uses to time and fire the fuel injectors, as well as the signal to run the fuel pump and the dwell signal timing to fire the ignition coil. A faulty ignition module can cause any one of these systems to malfunction.

That does sound like a malfunction with the ignition module inside of the distributor, and you can remove the ignition module and have it tested for free at most auto part stores.

If you do purchase a new ignition module be sure that it does come with a silicone grease or a die-electric compound because it is a heat sink and the ignition module will burn up without it.

To install the new ignition module first clean out the mounting surface inside of the distributor. Then completely coat the metal contact surface under the ignition module with a thick coat the silicone grease or die-electric compound and do not leave any of the metal contact surface of the ignition module un-coated with the silicone grease or die-electric compound, and be very careful not to over-tighten the ignition module or it will be damaged.

It would seem like a problem with the ECU or the fuel pump, but the common link between those two systems is the ignition module that is located on the distributor under the distributor cap, and that module is actually responsible for the fuel pump signal to run the fuel pump, the dwell signal to cause the ignition coil to fire, and also the signal that the ECU uses to time and fire the injectors, and you can remove the ignition module and have it tested for free at most auto parts stores.

I have replaced the ignition module 4 times already.


Sounds like you may have a bad ignition coil also,causing the module to burn up.

Which wire is the positive yellow or green on the ignition control module on a 1987 chevy caprice.. THANKS GARY


use a voltmeter, connect the black lead to the ground, then probe each one with the red lead. The one that gives you the 12V reading is the positive. Thats the surest way to find out.

No spark on 1987 chevy cavalier


Crank position sensor would be my guess.
Its located the center, rear engine area, mounted in the block below the ignition coil pack and DIS module.My guess is that's your culprit.
