My gsl-Se sometimes runs on one rotor. I think it might not be getting enough fuel because When I start it up after it's cold it runs on both when I get into it, she dosen't want to go and it shuts down one of the rotors. Change the spark plugs so thats not it. I'm thinking fuel pump. Let me know what you think.

 

What do you mean by shutting down one rotor? Need alittle more info on the symptons.

Check your fuel injector harness.

When I found that my car was doing this last year, when it would act up, I'd get out, open the hood, and move the wiring harness around where it attaches to the mount behind the alternator. Sure enough, the engine would purr to full function again for awhile. When the engine torques in the mounts or the harness was jarred just right, one of the rotors would go out again. After figuring out that it was the Fuel Injector harnesses that were intermittent, I went to Autozone and bought Borg-Warner replacement harnesses for the injectors, removed the upper intake manifold and spliced the new harnesses into place. Never had that problem since.

For $14 total ($7 each harness replacement), you can't go wrong. The only other thing that this could be is an intermittent ignitor, but usually when they go out, it's for good.

Check that and reply back, HTH,

 

that makes sense when I redid the intake when I hooked the injectors up again that was broken but would still coneected I'll see what happens. thanks.
