Message My car will not crank. Obviously that is a huge expanse of possible things that may be wrong, so I am going to try and narrow it down as much as possible. Also, I will try and add pictures when I can figure out how. My car ran, but had problems with hesitation, so I changed the EFI harness from Wiring Specialties. Great harness that fits everything. I have plugged everything in and checked and rechecked every plug. There are four that are not plugged in. Two for the wastegates, one up by the MAF plug, and a third plug by the ECU point. Both of the ECU plugs are hooked up.

I have pulled the number one coil and spark plug, and grounded it on the plenum. I have Spark.

I unhooked the fuel filter, and turned the engine and fuel shot out. I have Fuel.

The air intakes are in place and hooked up right. I have Air.

I have eliminated the FPRV and carbon canister, and rerouted the vacuum lines per a write up. I also took out the AIVs and rerouted the vacuum lines there too.

I ran diagnostics on the ECU, got a 55 code, so now issues there.

Please help and throw some more ideas to check. Thank you all!
