My service engine soon light (steady not blinking) on my '04 came on last sunday afternoon, by sunday night it wouldnt start, the starter cranks but the engine wont turn over. Its been sent in for repairs but i was wondering if anyone had any input as to what it could be, i think its the fuel system but who knows. i had the battery disconnected for about 2 hours whie running some hardlines for my stereo system could that have done anything to screw up the fuel system or ECU? any input would be greatly apreciated. i hope the thing is ready tomorrow i9m dyeing form being away form it... thanks....
