  • She starts great. wont run

    Hi all,
    My 99 3.8 BIRD will easily fire up then she shuts down. I can hear the fuel pump spool up so thats working. Have immediate power then she dies. Obviously has spark so what do y'all think?

            Last time I've experienced something like this it was related to ignition.

            So check your plugs, wires, coils and such even though you said you replaced the coils and you think the plugs are fine I would go through them again.

            If they are fine then I would take a guess and say MAF.

              Is it setting a ses light? You could just try unhooking the maf sensor to run in speed density. It could also be the crank sensor as well.

                Thanks for the advice all. I took some advice from a friend and used a pencil eraser on my key. Running great now. Guess the stock security system wasnt reading the key right. I never did get any codes but the security light was on and still stays on for a couple miles after start-up. Might be having BCM issues, lost the inside lights, rear defrost and horn. I was sure proud to cross over 214,000 miles.

                      Yeah I have a remote start that does the same thing at times. Starts up just fine then shuts off almost immediately. Just gonna reaffirm what everyone else is saying, the BCM/security system.

                          You deleted your BCM?
