Question:
i have a 2003 olds alero v6 3.4L that im having trouble starting. starts fine when its cold, hard to start when the car is warm or its warm outside. has been in and out of the shop. no check engine light so no codes. i had the fuel filter changed and pressure checked, crankshaft position sensor changed.(because thats what the dealer said the problem was.) air filter is new, injectors checked, sparks plugs & wires. car still has the same issue. any ideas what i could do to find the problem or what is wrong? when it is started it runs fine but idles a little rough. never stalls. when it doesnt start, i dont know if its just my imagination, but if i move the key to start without cranking it 5-6 times fast, it seems to start.

have them check electronic fuel injection sensors? sounds like a fuel delivery problem?Tell me if this is a good deal?
You may want to have your starter checked. On the GM s alot of times when the starter gets hot they won't turn back over when you go to start the car again. My advice is for you to get your starter checked.Have someone change the air temperature sensor,located on the intake plumbing.

If it cranks but just wont start after the engine is warmed up, and when it starts, it runs rough for a few seconds, the most like cause is the fuel pressure regulator is leaking fuel into the vacuum hose causing a rich condition. chech the vacuum hose after it sits for awhile for the smell of fuel. The vacuum hose does not have to be wet with fuel, just smells like it. The regulaot is near the throttlebody with a vacuum hose in the top, and a fuel line on the bottom running under the throttlebody.More Questions & Answers ...
