[quote:bdd194ba53="justanold"]HELLO! Does it do this on a cold start or hot? miles and trans and engine? recent work history? if it only does it on a hot start..describe the circumstances. 8) 8) 8)[/quote:bdd194ba53]

Its an automatic with a 2 litre and 117000 miles. I don't know the work history because we just bought the car. The problem is with a cold engine, If it was recently turned off, just for a few minutes, it will start up OK. My wife drives the car, and says the trick is to turn the key on 3 or 4 times before running the starter and it will start.

[quote:3899cabf59="justanold"]HELLO! GOOD description! your fuel pump is getting weak. replace it AND the filter. let us know how you fare. 8) 8) 8)[/quote:3899cabf59]

I replaced the fuel pump and filter and I still have the same problem. The car won't start until the 4th try. Sometimes, after cold starting, the engine immediately revs up for a second, then chugs a little for a second, before it idles normally.

sounds like a leak ..fuel pump??--> maybe...injectors???--> maybe ..if it has a pressure regulators not a returnless system???...pressure regulator ---> maybe... very interesting...any pressure reading n then PROCESS OF ELIMINATIONS by crimping 1 section at a time to see if pressure hold up to validate the leak yet???....huh?
