I have a question about my 2003 Monte Carlo SS. The first time I start the car for the day I just “bump” the key and it starts right up. After its been driven a few miles the second and sometimes the third start I have to let the motor turn for 2 or 3 seconds before it will start. I’m the original owner and the car only has 35k on the clock. I burn gasoline without ethanol and I’ve put fuel injector cleaner in it. Any ideas as to what’s going on? It does have the original air filter thou.


thanks..

 

Hello Blair. I am not sure what causes this, but I am having the same or similar problem with my 2001 MC SS. My car starts great when the engine is cold, but if it is at run temperature and I shut it off for about 10 minutes and then restart it, the starter spins several seconds longer than it should to refire the engine.

The two ideas I have is that either the heat is causing a fuel problem to the injector or the heat is causing a sensor problem and in turn a sensor is delaying the start. These are just my ideas, not sure where to go with them. I have read that heat will affect either the crank or cam position sensor and cause a failure.

Keep a watch on the forum and maybe someone will post a solution.

I am going to copy this to the Monte Carlo Repair Help thread, you may get a better response there.

 

Could be a lot of things, but it has to do with one of these 3: air, fuel, and ignition (spark)

 

i had a similar problem turned out to be the fuel pressure regulator. i would get the fuel pressure checked first and go from there

 

Thanks for the help guys!!

 

yeah thanks for the replies, car was fine till a month or so ago and it started doing it.....


Oh one thing I forgot to mention is that my car sat in a friends garage for 4 years until early this summer and he needed the space again so I brought my car home. Because of mine and my girlfriends health I didn’t get over there to drive it much or start it. I don’t know if that has anything to do with it or not. I’ve just filled the fuel tank for the 3rd time since I’ve had it back home (Sunoco Ultra 93). I know it’s worse on a car to just let it sit than to drive it. That’s why my car only has 35,000 miles on the clock. I did put in a can of Royal Purple fuel injector cleaner on the 2nd fill-up. I haven’t had it on the interstate since I’ve had it home to keep the RPMs high for long. Also I have the original air filter in the car.
