Asked by Feb 19, 2009 at 09:15 PM about the 2003 Chevrolet Cavalier LS

Question type: Maintenance & Repair

Past two weeks it has acted up a little when started.  Would not start right away.  Then it would start and not stay running like it wasn't getting gas.  Gas was at the bleeder prior to the injector rail.  Then it would start like nothing wrong.  The other day it started, and ran rough like not getting air or gas.  Changed the fuel filter, checked the air filter clean.  Started absolutely fine.  Next day would not start.  Pulled the icm and put back in.  Started, but would not stay running. Tried again, nothing.  Changed the icm, nothing.  Changed the crankshaft position sensor, nothing.  I am lost.  What is left short of taking to the garage?

does it start up right away after using it? does it only give you that problem when you first start it in the morning or if it's been sitting for a couple hours? why i ask is those cars have a oneway check value in the gas tank and if it goes faulty the gas will then sifin back into the gas tank and then when you try to start your car the gas lines have to reprime them selfs before it runs right or runs at all.

If the fuel filter ever gets plugged up, it ruins the fuel pump.
