Hi there! I have a 1994 Ranger 3.6L, V6, 5 speed manual that I've owned for about 5 years. Since summer started, it doesn't want to stay running if it is really hot outside and/ or has been sitting a few hours. I have no problem driving at night or in the morning. It turns over but won't pick up and if it does it revs above 1200 RPM only to die a few seconds later.
I recently took it in and the repair shop could not duplicate the problem - of course! Like taking a sick child to the doctor.
The fuel filter was fine as were the volume and pressure.
There are no other problems with this truck. The gas gauge is accurate and the tranny was overhauled and the fly wheel was machined Fall 09. There are no fuel or tranny leaks either.
I've researched this problem but haven't found any similar issues with the heat being significant. I don't think it's the fuel injectors because it doesn't run rough when it finally does decide to get going.
Any suggestions? I want to avoid dropping hundreds of dollars to see if it's the fuel pump if I haven't tried other options.
Thanks a bunch!
