87 oldsmobile toronado not getting any spark

An '87 Olds Toronado has three computers: the ECM (engine control module), the BCM (body control module), and the IPC ( instrument panel cluster). The A/C compressor is controlled by the body control module.

What codes? Why did you replace the crank sensor? Do you have spark at the plugs? Do you have fuel pressure? Is there a message in the dash display?

Sounds like you have many more than just one problem. It really doesn't pay to throw a bunch of parts at a problem and hope it's fixed. The climate control head display shutting of and coming back on at 75 degrees is most likely due to a bad Central Power Module, a common problem in older Toronados. Hard to find, not too hard to replace. It's under the dash to the left of the steering column. The no spark problem could be any of several things. Did you check for good cam and crank sensor signals? Do you have spark at the plugs? Have you changed your plugs wires? Do you have any stored codes? If the console says there is an electrical problem, you can be assured that there is indeed an electrical problem somewhere. It may not have been severe enough to cause a concern for the past seven years, but it may be worth taking a look now to see if has anything to do with what going on. Replacing the oil pressure sensor is easy enough and inexpensive enough as a first attempt to fix the gauge readings acting funny.

did you give it a tune up change plugs fuel filter

you can fit coilspring boosters. it is rubber spacers that fit inside the spiral of the coil spring. you get different sizes for height adjustment from your local spares shop.

Check the fuses.

should pull ignition control module under the coils n take to any parts store to test it

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.

On Type II coil packs, the coils can be replaced separately and the ignition wires are all on the same side of the coil pack.

With Type I Ignition


With Type II Ignition

it does not matter but the plug wires going to coil pack have to be exactly where they go, they can not be mixed
