So when we went to start the car, the car would not start we replaced the battery then we replaced the alternator. After looking some stuff up online we realized that it was neither of these things it was actually the passlock security. It is now locked us out and we cannot get the car started unless we go and have a whole new ignition tumbler keys and I believe it is the bcm reprogrammed. This is obviously a malfunction in the car and I don't believe that I should have to pay $300 for a malfunction I don't know if you all can help me but anything at this point in time would be helpful.
Had to charge battery so I could take car in for ignition recall. Since I dont use the car much anymore. Upon trying to start vehicle, engine backfired and upper intake manifold exploded and pieces all over the driveway. This is the same issue as described in the 2004 recall which was performed on the fuel pressure regulator. Since the recall. I did have to replace the fuel pressure regulator again around 2011. I also had replaced the upper and lower intake gaskets that were faulty oem parts. The upper plastic manifold was replaced to the newer design. Although it being plastic is just an engineering catastrophe stil doesnt solve the problem with warping from heat. Anyway. Heres my diagnosis. Fuel injectors continued to spray fuel into engine after the first attemp of starting vehicle caused by a weak battery. I say this because after turning the key off after the first attemp I heard the fuel pumping for at least 10 seconds. This is not normal. After 1 minute I tried to restart and thats when parts started flying. Good thing no helpers had their heads under the hood when this happened.
