I've checked the battery connections. Now is there any way to check the ignition without having to change it? Like I said I already bridged the starter relay while the ignition is in running position and the engine cranked but it didn't turn on. Another question, when this all started the clifford alarm that was installed in the car was acting funny, its there any way the factory alarm won't allow the car to start? If so how can I disarm it. I read another forum about there being a green wire on the driver side door that is used to disarm it, I will try that today and hope it works. Any other ideas? like I said earlier the car I was driving down the street and the car just shut off, I doesn't crank but all of the dash gages light up and seem to be working fine. Thank you for your replies and please keep them coming.
