I finished my EFI swap a month ago and have been finishing the brakes, hydroboost and suspension since then. It fired right up and ran perfect even though I had not installed my o2 sensors a month ago. I have a 96 Explorer motor with RJM harness and mustang distributor/coil/computer. I got codes 81, 82, 85, 84 before initial start up last month and it ran great.
I still have not completed my exhaust and yesterday I went to start it and it will fire up for about 1/2 a sec and dies, it does not change if I give it the gas.
I checked fuel pressure and got 40 psi and checked codes and got 81, 82, 85, and 84. What next?
