1996 Cadillac Seville SLS Q&A

1996 Cadillac Seville SLS Question: 1996 cADILLAC ENGINE WON'T START

I just put in a used engine into my 1996 cadillac seville. The car won't start due to the previous alarm that was installed. I had to change the engine due to blown heads. I don't know what else to do. I tried turning the key on the drivers side door and disconnecting the battery. That approach did not work. PLEASE HELP!!!!!! -
Answer 1
Does the engine Crank Over but won't catch? Or it won't even Crank Over. If it Cranks over but won't catch the first thing is to check for spark, then for fuel delivery. The alarm will cut the injectors, ( no fuel delivery ) but the engine will crank over. -
