I have a 1988 jeep comanche w/ inline 6. It starts but dies immediately. I changed the rotor cap, plugs and wires about 3 months ago. They seem to be in good shape and it has been running fine until now. Plenty of fuel to the injector rail, none coming out of the return end after the pressure regulator. It will kind of run for a little while if I pump the gas. Any ideas?

So it has spark the entire time? Need to verify fuel pressure, If it is MPFI it should have 31 psi of fuel pressure, anything less an it wont run properly or possibly at all
