I have a 1998 chevy 1ton quad cab four wheel drive I cannot figure out why it won't start. I have vurtually tried everything I can think of the only thing I have let it could be is some kind of security or main computer problem the motor came out of a 1999 pick up it ran great when I pulled it out so im not sure I thought the motor that was in there before was bad so I had it pulled still having the same problem plenty of fuel just no fire I have replaced the ignition wiring it will turn over but I have checked I am not getting any fire from anywhere need help bad
