I have a 2001 ss 3.8 with 70,000 mi. car starts on first cold start and runs good . after car is at operating temp and is shut off it will take several attempts to restart once it restarts runs fine? I have had this car for only a few months and like it alot, want to fix this problem anyone have any advice before i start changing un needed parts, there is no engine service soon light coming on....... Thanx

 

when you turn the key does it turn over fine but refuses to start? Almost like it tries to start too soon? Mine does the same.. Possibly the starter?

 

Hot start problems can sometimes be a telltale sign of the MAF sensor going bad.

 

I agree with Chibi, could be the MAF. Next time it happens, unplug the MAF and try to start it.

It could also be a failing crankshaft position sensor

 

There are a few things it could be. As stated above by other people it could be MAF sensor or crankshaft position sensor. I have also seen fuel pumps cause a similar concern.

 

I appreciate all of your help and advice,I will check fuel pressure and unplug maf sensor if I do that should car start or not?

 

wonder if it could have a tuned pcm under there and he not know it? always a possibility. where are you located? there could be someone near by with a tuner that can scan your car and look for issues there and tuning can fix start up issues easy.

 

I am in uniontown p.a., just bought this car and dont know if anyone has tuned pcm. Did a car fax before i bought it and appears stock had only 69,000 mi on it and had been serviced reguarly.....

 

If you unplug the MAF it will use old data, but your car should start easily and you'll know the MAF is bad.

 

I'm gonna go with the fuel regulator going out. My car has a little hiccup starting sometimes and my step mothers 02 Impala had the same issue, we replaced that (about an $80 part) and wa-la - fixed. I plan on doing the same thing here soon.
