I was supposed to go tomorrow and get the supercharger tune done, but I did something 2 weeks ago and suddenly it won't run, I put on the oil pump that this motor came to me with(Melling 68A).
Since that was one change I made between the last time it ran, yesterday I put back the standard Ford oil pump back in.
I have a real bad misfire that is creating a backfire in the exhaust and it's very difficult to get running at all.
It's down on power since half the cylinders aren't firing...I have swapped TFI modules with tested good ones, swapped the cap and rotor, swapped the computer(along with the chip) and it doesn't help at all.
What are the other things I can check?
I have spark(checked with a tester), I certainly have fuel(constant 40psi at rail and STRONG fuel smell after trying to start)
