    For a quick check you'll need a T- fitting in the fuel line to the rear of the cylinder head to hook your gauge into for testing purposes. The OEM would put a fitting into the secondary fuel filter base on the supply to the cylinder head for a gauge in the dash.

    How's the truck been doing? I talked with someone from the Greely area awhile back and was asking me questions about it.

    I remember the trouble to flash, I'm positive that the problem was the Data Link between the dashboard diagnostic plug and the ECM after thought about it later. I'd be willing to bet it is an injector

    I have an ECM, give me a call
