On my 92 Caddy, it wouldn't crank. I also had to wait 15 minutes before I could try to start it again. Then it might start and other times it would take an hour or so before it would start. Mine was basically hit or miss., sometimes it did it sometimes it didn't.

Is there any mechanical type sound when you turn the key all the way? I know if you have a bad solenoid in the starter it wont rollover. My car scared me a few times not wanting to fire and we found out it was a bad solenoid but somehow it fixed itself after finally starting and running like a tractor for a few mins.. there was a clot in the engine which made it run like a tractor (diff story) but the reason it wouldnt start was a bad solenoid.

Hi did you figure out the problem?I have a 97 Deville that is doing the exact same thing.

Nope I still haven't figured it out... We put a new starter in the other day because my dad was convinced that was the problem, but when we attempted to start it the car made a low chug like sound of wanting to start then faded in to silence and started smoking like crazy, and now that starter is also fried.. what the f***..?

Have you tried to manually turn the engine over by putting a breaker bar on the harmonic balancer bolt?

You know you can read fault codes right of the dasboard from the river information center (DIC). if you pull codes it will at the least send you in a direction. I have a link that will instruct you how to pull codes & identify them from a list.

If you dig around in this site you will find some really good caddy solutions.

Thanks so much, this link looks like it will be very helpful!!!!!!

After you pull codes & right them down look for the list that identifies them somewhere in that site.

If you think you screwed up, just turn off the key & start over again.

When codes come up they may display if they are "current" or "history". the history codes are less important and they could actually be cleared to see if any of them come back.

A low battery can throw all kinds of codes that are insignificant.

If there is something that you don't understand the info is in that site somewhere.

After you are sure all codes are recorded correctly you could go ahead and clear them all per instructions.

This is a nice feature only Cadililac had for the OBD-1 & OBD-2 -other GM cars needed code readers.

Your 1994 Deville is OBD-1

When you do clear the codes the car may allow the car to start up or you....Maybe

It has been known that the under hood fuse block with relays can become contaminated with corrosion & to simply pull & inspect the contact blades on these fuses & relays for a whitish coating may remedy troubles just buy cleaning them. These contact blades that plug in have an zinc plating on them that resembles a silver/aluminum in color. If they have no whitish powdery substance on then they are most likely good. As you do that this is what a blown fuse looks like-
