This car has 2 fuel pump relays, one with a resistor, and one without. The without is for starting and hard accel, which is working:), the one with resistor is for everything else, which isn't working:frown:.
The relay with resistor isn't being energized after the car starts, so it dies after just a few seconds. Seeing both relays have the same part number, I switched them thinking it might be bad, no change. I'm also getting DTC P201, mass air flow sensor low input. Evidently both problems are related seeing they happened at the same time, highway speed and then suddenly coasting dead:mad:. The service manual says 5.5v shoud be reading from the DCM, it is:). It also says it should light a test light on the terminal coming from the ignition to ground, dead on that one:frown:. What could cause this?

Thanks,
Steve

Welcome to AF.

Actually both fuel pump relays are used for starting and normal operation. One is the fuel pump relay and the other fuel pump speed control relay. Try bypassing the fuel pump resistor via the speed control relay. Let me know if you need the procedure.

On the DTC a typo? P0201 is a fuel injector issue.

Thanks Bob.
Yeah, I guess the code is 102. Whatever the MAF low input code is. I wrote it all down at home, but didn't bring it to work with me. So I should be able to bypass the the resistor by jumpering the correct terminals on the underside of the terminal block?

You're welcome.

Yes, you can remove the speed control relay and bend the tab on the relay which matches up to pin 85 on the relay socket. This will force high speed mode only for testing purposes. See link below which is for for a L67 equipped Pontiac Grand Prix but the Regal GS/GSE is similar with the exception of the relay numbers.

On the MAF DTC of P0102 (low frequency below the threshold of 1500 Hz) you can try cleaning the wire element with MAF spray cleaner but in most cases probably a bad MAF sensor. Good luck!

Thanks a lot Bob. The problem was the resistor. The MAF problem was a blown ignition system fuse. Apparently the second time the motor shut down so abruptly at 80mph, it overloaded one of the ignition circuits.
