My car will not start sometimes. And when it doesn't start, it's usually down for about two days but will run for maybe four days. I keep my Eldorado maintained. Regular oil changes, etc.. Just bought a new battery and tires in December. I doubt it's the anti-theft system since it doesn't give directions on removing my key although it did one time a few months back. Hasnt done it since. But anyways, when I can't get my vehicle to start, the Service engin soon light comes on. No flashing or solid Security light. When it starts, the service light is off and showing no signs of problems. I have had my idle control and heater core serviced in the past and I did the pull down switch repair myself. I have been seeking help all over the Internet but all that I can find is on the Anti-Theft System. I am thinking it's my ignition switch or coil. But how could I know?

will a bad water pump set senors off when read by a computer

Ad starter is disabled

Seems to be random. It usually goes off in the middle of the night, but sometimes it goes off in the middle of the day. I'm certain that it's not someone hitting it and I have just put a new battery in it. It was doing it before and it's still doing it.

The lights and horn is constant when I changed the battery

drove it this morning an it over heated checked my coolant level added coolant and drove back home now car has no power at all

Can you give me an estimate for installing a Jasper engine including cost/labor?
