I swapped the wires one at a time so am 99.9% sure the order is correct. I will start with the fuel pressure and spark tests. The fuel tank was completely emptied and cleaned then 5 gallons of fresh premium put in. I did not specifically blow out the lines but hopefully that wouldn?t be enough to kill the New injectors.

I did notice the tach was quite off which I initially contributed to the gauge cluster common problem. However when I displayed the rpm on the HVAC screen it was matching what the tach displayed (which was going up to 9k rpm though you could clearly tell the engine wasn?t that high). I read another post on here about a non start due to failed crank sensor.. so now I?m thinking i should test/replace it.
