I replaced the coil, cap, rotor, plugs, wires. I checked and reset the fuel pressure. I put noid light on the injector harness at all the injectors. The injectors were flow and bench tested before I installed them. I verified the PIP is working and advancing the timing on the distributor. I took the TPI in and it bench tested good at AutoZone. I pulled the KOEO codes and its not throwing any codes. I pulled my EEC and checked the board for any burnt up spots, recleaned the pins for the connections on my moats chip. I checked the TPS voltage and insured its good. Only things I haven't tested are the O2 sensors, which are brand new motorcraft, and the MAF. I unplugged the MAF at idle and the car died. I am not sure if that's normal. I couldn't get the car to run the KOER test or cylinder balance test.I need to get my electrical issues taken care of, then I will take the car into the builder to do compression test and leak down test, and check the lash on the valve train. They are already going to be doing a rear main seal since it is leaking a lot.</blockquote>
