2000 mercury grand marquis wont start...

[bradw1984]

I have a 2000 grand marquis that was stalling every time i came to a stop, so i took it to a couple shops and one told me to have the computer checked, so i did and it passed, so i had it checked out somewhere else and they couldnt figure it out because it wouldnt stall on them. so now it wont start at all and i dont know what could be wrong with it. anyone know what to do???

I'd clean the throttle body and IAC first if you have them.

Try holding the gas pedal down slightly when you crank...if it starts but stalls when you take your foot off, it's the IAC. Cleaning it sometimes works, but they aren't expensive if it doesn't.

They aren't expensive?? I just got one yesterday to the tone of $90, and I've seen higher prices.

Compared to buying a new PCM, or an LCM or an EATC head unit or a new radiator fan assembly...now THOSE are some outrageous prices.
