Engine starts, then dies.... 700 1991

posted by  someone claiming to be Mark from buffalo on  Fri Sep 17 14:12 CST 2004 [RELATED]

Greetings,
Ive had this 740 wagen for over a year, love it, but within the past 4 months, starting has been progresivly worse. It starts, revs, but then dies. I turn it off, and on my second try, it starts fine and stays running fine. It happens every morning now. I would run the pump 3 or four times befor starting, and that made no difference. I replaced the fuel pump, fuel filter, amm, and Idle Air Meter. I looked up the faq and couldnt find the answer. Any help?
Thanks much,

Have you cleaned the throttle body? A dirty TB would typically give those "start-and-die" symptoms described.

See if it starts with the AMM unplugged. If it does, but not when connected, the AMM is bad.

you don't mention resolder of fuel and radio suppression relays nor the replacement of flywheel sensor given it's age.

This is a really common problem on the 740's. You may need to clean out your idle air control valve. Give it a try
