Question about 1992 Oldsmobile Cutlass Ciera

1 Answer

Can't get 1992 Cutlass Siera to start,it tries to start,only for a second,and kind of backfires. Already replaced coil packs,plug wires, oxygen sensor,still does the same thing.I believe the engine has very breifly tried to start without the drive belt on,would this throw the engine timing out?If so,how hard is is to get it back in time?

The mechanic should check on the ignition system first . Check the ignition switch, the ignition coil , the spark plug , the spark plug cable , the distributor assembly and the wires and the fuses.Check if there are worn out or destroyed then replace it. And then set the distributor timing mark and the firing order of the spark plug which is 1,3,4,2.These 1,3,4,2 are the number of the spark plug connecting to the distributor assembly.Then try to start the engine .The cause of the engine back fire is ignition timing not in order.

It's grey and has a vacuum hose attached to the top of it. Towards the front of transmission. Check and see if the hose has a leak. You can manually shift it from first to second with the shifter.

Trying to find the engine control module for 1991 olds cutlass siera sl

The ECM is located right behind the glove box. First remove the negative (-) battery cable. Then remove the front of your glove box, just a few small screws. The interior of the glove box is cardboard and will pull out after removal of screws. Then unplug the 3 electrical plugs and let them hang out of the way. Now, remove the bolts on the side of the bracket holding the ECM IN.

I have a 92 old Cutlass Siera, the lighter socket

First I would check to make sure that the A/C compressor isn't locked up as that may be why the belt isn't on it. If the compressor is bad then the repairs can become very expensive in a hurry. $600+. There should be a seperate fuse just for the lighter, usually a 20 amp that says "CIG LTR" located at the underdash fuse panel. You could have a bad or worn lighter socket but usually the wiring is fine unless someone has tapped into it for an aftermarket stereo system.

Brake lights

There is a micro switch at the top of the brake pedal that activates the brake lights when you depress the pedal. This switch likely has to be replaced. Any mechanic can do this in about 15 mins.
