    A black 2000 hyundai elantra. I only kept it so long because I wanted to be personally responsible for killing it. It was a personal kind of thing.

    If it has **** or tires, you are going to have problems.

    Finally got a chance to look at it. If I take the wire from the coil off the distributor and stick the electrode near something metal and turn it over, I get nothing. Clear indication of no spark, eh?

    Time to go crawl around and see about that ground wire. How can I test the DME relay that was mentioned?

    Eliminate one of these two and go forward from there.

    Verify you have no injector pulse as well as no spark. If you are missing both, then look for problems that relate to both fuel and spark, such as bad CPS. If you dont have a noid light or high impedance ohmeter, you can often just listen to, or place a finger on the injector while an assistant cranks to see if it is clicking.

    No starts pretty much all start the same way, check for both spark and fuel, it makes a difference in diagnosis if you have no spark, no fuel, or neither. Cover all the basics first before moving to exotic things. Check ALL the fuses with a test light on the back of the fuse, make sure you have power to the coil and injectors etc.

    let us know what you find.

    Finally was able to dig out the Bentley. I didn't test for spark the right way, so I'll do that again once I have someone to turn the motor over. All the fuses test fine. My cheap ohmmeter appears to be malfunctioning as I can't get it to read any resistance at the harness connector for the CPS, or anywhere else for that matter, so I can't say much about that just yet...

    Sad to say this has been one of "those" cars since I bought it in the spring. Hopefully we'll get all this business ironed out together soon...

    Ding! I borrowed a friend's "real" multimeter and the resistance at the CPS harness connector was roughly 200 times what it should've been. I just installed a new one today, and it started right up! (with a jump...the stupid flashing alarm light the PO had installed drained the battery during the car's downtime, I guess).

    Thanks for pointing me in the right direction!

    Its either fuel or spark. but if it happened while turning off the a/c it possible it could be a electrical problem. Try swapping relays for fuel and ignition and also check every fuse and fusable link, under the hood and under the rear seat.
