In response to your answer regarding my dad's 96 Lincoln Town Car dieing and not starting up for 5 to 20 minutes, I talked with him about your answer back. He did tell me the last shop tested his fuel pump, which was fine. So he said when his car has died, he sprayed starting fluid up through the air cleaner, which the car would start, but as soon as the starting fluid burned off, it would die. Some times he has gotten it to run. What I'm wondering is if there isn't any juice getting to his fuel injector, is this how it would react? If this is the problem, what electrical source powers the injectors? Can that be the culpret then? It sure sounds like the injectors aren't getting the juice to spray gas into the cylinders. Is this correct, injectors need juice to spray fuel into the cylinders? The plugs are firing. No check engine light has ever come on. What's your opinion on this possibility? We thank you for your input on our dilema. Hopefully we may have finally found the answer that no shop has ever been able to determine.

You can use noid light too check if injectors are working electrically. If it starts with spray start then injectors are not delivering fuel/enough fuel. The computer system triggers the injectors. Some anti theft systems disable the injectors not sure if it pertains to yours.

Then can the computer make all of them not to get fuel and then sometimes work just fine? Not sure why waiting from 5 to sometimes 20 minutes and it will start again. Maybe cooling off has something to do with the injectors working. This is why we're confused. Can a faulty computer be causing this whole problem. We will check the injectors as described on this site under how to test fuel injectors. If it's the computer malfunctioning here and there, we might not find the problem by testing them. I'm wondering, this does die on my dad going down the highway or even in town. He has let it sit for some time and got it to start back up. Once he got it running, he shut it off thinking it was ok then. When he tried to restart it, he had to wait again before it would start. But if he sprayed starting fluid into the aircleaner, it would run until the starting fluid was all used. But sometimes it kept running. Even telling the shops he's taken it to, I don't believe anyone has ever considered it might be the injectors. That's why I was wondering if the computer sending trigger pulses of juice, just might be faulty, and working intermittently. Is there a way to test the computer, or narrow it down to that itself. I really appreciate all your help, but we've put out so much money already, and haven't gained a thing from all the shops it's been in. My dad, at this point, doesn't want to spend another dime. He's quite old, and feels like all these shops are ripping him off. That's why I stepped in and am trying to help. He doesn't have a computer, or even knows how to get online, so I'm doing it for him. Hope you can maybe give us some light on this subject. Thank you so much.

I once had a car that the idle was jumpy and I tried lots of stuff but finally just lived with it then 1 day I decided to switch computers since I had gotten another from a wreck to use and when I changed it it was no different so I went to change it back and I decided to regrease the connector when I noticed that 1 of the connector wires(20+) was showing it's metal prong sticking out the back where the others weren't. So I shoved it back into plug evenly and reconnected computer and PRESTO, perfect idle. All i'm sayin is you could be up against somethin sneaky like that?
