i have a 1994 cadillac eldorado touring coupe and my motor might have an internal fuel leak.i was told that it just needed new injectors. i replaced all eight injectors and put a new fuel rail in the car twice. both times after i replaced the injectors and fuel rail both times when i turned the key to start the car it blew my intake manifold off the car and it caught on fire both times for about 30 seconds each. before i replaced the items my car never did this. could i have hooked up something wrong or could their be a fuel leak somewhere. is their any other motor that is compatible to a 1994 4.6 northstar motor. anything out of any other cadillac or a 4.5 or a 4.9. do you think the fire being set for about 30 seconds ruined my motor?
