S.O.G. Posted May 20 Share Posted May 20 YouTube Link Video shows symptoms. Drove the Z to a friend's house, camped out in it overnight, used the battery to run a fan. Battery wept and humidity made a lot of corrosion underneath, but the wires are good. Tried jumping it with another V8 before swapping battery, to no avail. Bought a new battery and swapped it out, same symptoms. Tried starting in P and N. Need to get multimeter out of storage to do more testing. As you can see from the video, it builds rail pressure in between 20 and 40 PSI, but then just keeps looping that. It never stops priming and never reaches the desired number. The engine never turned over and the starter always clunks. It feels like it's being stopped by something that isn't the starter or motor though. Fuel pump is in-line/out of tank. Absolutely no symptoms from starter or fuel pump prior to this, car was running well. FiTech is showing no codes but I have a battery disconnect switch that I use every time I park so it probably won't be showing codes. Has anyone come across anything like what the video shows? 02 Camaro LS1, 4L80e, Ford 8.8, FiTech EFI Quote Link to comment Share on other sites More sharing options...
