car has fire but no fuel at injectors fuel pump working. won,t start

Will it start/try to stat with the starting fluid? How much fuel pressure? Got injector pulse when checked with noid light?

many things such as timing, ECM, fuel pump, EFI main relay, fuses such as AM2, faulty new parts (distributor), wiring, CKP sensor can all cause a no start condition as well as bad intake valve(s) leaking by. Recommend take to a certified professional based on all you have already done with no success. Call Jim or Michael at CarMasters 757-237-7080 to arrange having vehicle brought in for diagnostic.

Did you check the pressure between the pump and the filter? 70 psi is higher than specs, if you checked it before the filter it may be clogged. The normal pressure with pump running - engine off: 38-44 psi. Based on the high pressure and no fuel at return line I bet there is a blockage somewhere in the lines or clogged filter.

is it a v6 ?fuel damper clogged?
