Some of the modules are aluminum and the are mounted to the steel to make the ground. The aluminum oxidizes and loses contact. I usually use a fine sandpaper and clean the mounting surfaces. I have also added a ground jumper wire from a mounting bolt on the module to an engine bolt to get a good ground.

SOURCE: Ignition module wiring on 85 f150

The red wire goes to constant hot and the white wire is on the key on/off. The green is a tach signal and the black is ground.

SOURCE: car wont start

I noticed you replace the crankshaft sensor, but not the CAMshaft sensor.
The Ignition module takes the input of both sensors to tell the coil when to energize.
This sensor should come up as an error code when you attach a obd reader.
Even if your light is not on - there may be a code. If it is not your vehicle originally, some people pull the bulb!

Why does my ABS light stays on and sometimes i get a vibration in the brake petal causing my 2002 Cadillac escalade not wanting to stop?


Sounds like a fault with the Antilock Braking System. The vibration in the pedal is the ABS working. With your foot on the brake pedal, it releases and re-applies the brakes to stop a skid from the wheels locking up. You need professional service for brakes.

Seems to be a known issue on all Cadillac and requires the ABS module to be replaced.

Hi I am working on my 1993 cadillac seville sls 4.9l engine. It will not start


Wow... Thats a lot of parts replacement for what may be a simple problem. The vehicle needs fuel and spark to start ( along with air and compression ).Is there spark from one or more spark plug wires when one is disconnected and held over a grounding point while the engine is cranked over? Is there fuel supply? Pressure to the fuel rail tested? Check the basics before you invest tons of money in an older vehicle

My 2003 SLS A/c fan shuts off and later comes back on to shut off later. The compresser keeps on running durring that time.


There is a ground wire on the passenger side under the kick panel near the door jamb. Check it. If not, probably the fan control module. You will need to check for proper power & ground at the module before replacement. Bolt in part $200. Take glove box apart to get to it
