Question about 1987 Oldsmobile Toronado
I have replaced the coil pack and still not getting any spark what could it be?
Posted by Anonymous on
ECM requires both crank sensor signal and cam sensor signal to fire the coils. Check for spark at the plugs first. Check the plug wires, then the coils. Only if you have no spark at any coil would I suspect the ignition module, and even then only if you have a good crank and cam signal. Do you have any codes stored in the ECM? They could help pinpoint the problem.

Check the spark on each plug wire with a calibrated spark tester.One can be bought at most parts stores.If two plug wires that are next to each other are bad then replace coil pack.There may also be a bad ignition module.Also check the crankshaft position sensor.

reset the ec module by disconnecting the battery for a few minutes. If that does not work have autozone do a free scan and ask them to reset the codes.

Not hard at all. Seven bolts and one connector. No computer work. But you need to know if it is the front coil or back coil. Front coil for cylinders 2, 4, 6. Rear for 1, 3, 5.
