    Ok I’ll re test pin 86… I didn’t have a second hand to turn the key on before. My 7 year old has volunteered for the task. I will also trace pin 4,5,20 to their grounds

    I’m unclear about pin 86…. I’m running an aligator clip from the negative batt terminal to the neg of my volt meter. The fp relay is slightly pulled out so I can test the pins Can u explain how or why pin 86 shows 12v?

    Yes I told Bob that my fuel pump relay ground was the issue… he said everything bench tested fine. He said i had an oil pressure code stored that he cleared. I’m Not sure if the oil pressure code would stop the fuel pump as a safety feature

    Pin 30 85 and 86 have 12v with the key on for the fp relay….. shouldn’t pin 86 be the negative from the ecm?

    The wire from fp relay pin 86 has good resistance to j1-23

    So my problem is the ecm is not supplying the ground to the fp relay…. Correct?

    So if pin 86 on the fuel pump relay does not lose voltage for a few seconds when the key is turned on. My problem is the ground on relay #14?

    Ok my numbering in the above pic is incorrect. 30 on the left or 9 o’clock position 85 on the bottom or 6 o’clock. And 86 on top. Based on that, the relay on top is #14 And the relay on the bottom is #1 which is the fuel pump
