Default Drove it yesterday, doesn't start today? 97 se sc

Took the battery to Orielys. Because I noticed that a light was one for two nights. They said the battery had a partial charge and charged it. Other than that it has been running great.

It turns over well. All cabin liights come on and all the usual noises no clicking or anything. Just wont fire. Im not sure how to check if its getting spark.

Anyone got suggestions.

So it'* cranking, but not catching?

If thats the case, I'm sure you have checked the fuel at the rail; ignition fuse? I think there is one.

Not sure what duel at the rail is. Is that the tube that goes across the top of the supercharger. And where and what is an ignition fuse? Thanks

He wants you to check the fuel pressure. You can check for spark by pulling a wire off a spark plug and inserting a spare plug. The base of the plug needs to be grounded. Have someone crank the engine while you watch for spark. Keep fingers away from rotating parts. Check for spark from all three front wires.

Allright, I found the ignition fuse and it was good. Still not sure how to check the fuel pressure. But I can go and check the spark. You say on the front. Usually if we get one we are ok right?

Any reason why the front three? And not the back?

The front 3 are easier to get at & see. You need to check three because there are three separate coils.

Ok. I checked all three and got no spark. I remember doing this on another car and you usually get sound and a sparkd right? I didnt hear or see anything on all three up front. Plus I pulled a spark plug wire off an it broke, bummer.

Ok, and what is next? Thanks

Well it least we might have the problem narrowed down. Are you sure the spare plug you used is good? The coils mount on top of the ignition control module (ICM). Let'* check where the wires plug into the ICM. Unplug the connector & check for corrosion. If you don't see any plug it back in & check for corrosion where the plug wires attach to the coils. Do one at a time so they don't get mixed up.


Edit - Sometimes you can hear the spark & it can be hard to see if your outside in bright light. Should be easy to see if you're in a garage.
