Click the search button then the blue link. Not elegant but it worked. I didn't undue the regulator harness at all either? Observe the Actual fuel Rail Pressure and Desired Fuel rail Pressure parameters with a scan tool. All these years I've tried to devise an elegant test. Well its a ecm or bad connection in the connector to the ecm if you plug the ecm in tight it throws all sorts of codes leave just a smidgen loose nothing can drive down dirt roads ect ect bumps don't affect It?

A copy of the part request, repair order with technician comments, snap shot of the preliminary actual fuel rail pressure vs desired as commanded by the Tech 2® and the completed diagnostic worksheet should be included with the injectors.

We also ran a pressure test at 40 and it says that only cilinder 4 is working at the proper pressure. This high fuel pressure is detected by the fuel pressure sensor located on the fuel rail. Is the Actual Fuel Rail Pressure Parameter within the specified range 1-1. Start and idle the engine.
With a scan tool, observe the Actual Fuel Rail Pressure parameter. Jan 06, 2018 could be a steering wheel sir coil,,,behin d the steering wheel there is a sir coil which electrically connects the air bag to the car thru this coil that allows the steering wheel to turn with out getting twisted wires,but sometimes that coil and have intermitent contact and give a air bag light at times,could be other things , but most likely that,no way to check it,,,get the trouble code and that will lead you more in a direction on it,,prob just gotta replace it, i would take to dealer if you misinstall the new one you can wreck it,, Oct 07, 2009.
