Hello and sorry for the delay! I do apologies as I cound not find the link to this question. Anyway, we are addressing the no start condition? Have you checked the inputs to the fuel pump relay while cranking? There should be two powers and one ground. One power comes from the ECM B fuse and the other comes from the vehicle control module or computer. Can you tell me which one your missing?
