    I have a 99 GTP. And it needs to be cranked several times before starting. I've taken it to a mechanic and it was pulling the P0401(EGR insufficient flow), P0405(EGR sensor A short), and P0650(malfunction indicator lamp) codes. I was told I need to replace the EGR (replaced this twice thinking the first one must have been faulty), Mass air flow sensor, and my PCM. All have been replaced and it's still pulling the same codes. Any ideas why it would pull all 3 of these codes?

    Ok, so it's pulling the codes. But is it still a pain to crank?

    pull the vac line off the FPR, does fuel come out and or is it wet?

    If so, thats your hard start problem.

    Ok, so yes it's still hard to start and when I bought the EGR valve it said disconnect the battery for 30 mins to clear the codes, which I did.

    On the FPR, should fuel come out or should it be wet? And if that's my problem, what does that mean? How do I fix it?

    You dont want fuel to come out or for it to be wet.

    The regulator holds the pressure, with low pressure the car doesnt want to start with no fuel there.

    SO if its bad, replace it.
