1999 Oldsmobile Aurora.
Question = When starting you have to keep trying to start, engine turns over but will not fire. Sometimes we have to try several times, but it finally starts.
Sometimes it starts right away and many times you have to try it several times. Temperature does not seem to effect it. Warm or cold it does the same thing.

There are several things that can cause this. The most common is a leaking fuel pressure regulator. When it leaks, it leaks fuel into the vacuum line causing a rich condition.

Another is a weak fuel pump. Have the fuel pressure checked when the problem is occurring. Clean the Idle
Air Control valve (IAC) as well.

GM dealer has trouble shot, cannot duplicate.
Question = my 2001 Oldsmobile Aurora ignition key sometimes cannot be removed. This only happens on hot summer days here in Houston, 85-100 deg, after the car has sat in the sun all day long. At the end of the day I start the car normally and drive about a 1.5 miles. Stop, put the car in park and turn off the engine. The engine stops and then the key will not rotate to the off position. It stops just a little past the accessory position. Transmission is not locked at this point. If I drivelonger (i.e. Further) the problem is not present. This problem started last summer but all this past winter the problem did not occur once,it came back this summer...
