Thread: Hard starting problem.... but easier with remote starter??

If it starts perfectly with the R/S and not with the actual key, chances are, it's the R/S wiring or the immobilizer that's causing the issue.

Put your key into the cylinder, turn the ignition on(don't crank) and remote start it. if it starts flawlessly, your question is answered.

I tried turning the key on/eng off waiting, then using the remote starter and got the same results.

I also hooked up an actron scan tool and watched the ST TRIM and LT TRIM and they stayed within the parameters. Also with the car running, I removed the vacuum hose from the FPR and waited a few minutes and no fuel ever released from it, and also no smell.

How else can I test the FPR?

And how else can I see if the immobilizer for the remote starter is the problem? Or is the above post the only testing method? Am I correct in my understanding of what the immobilizer is?.... It's a bypass that's needed if you have a chip in your ignition key?

I meant turn the ignition on and Keep it on, then remote start. This way, both keys are being read at crank time. The immobilizer in GM vehicles is referred to as a "passlock" system. And if activated, it will disrupt the fuel pump from working.
