I have figured out the wiring harness and wired in new plugs for the fuel injectors. I am using the cheap Chinese new-type fuel injectors instead of OEM. I have a '91 Nissan NA 2+2 300zx. The car will crank but will not fire/combust. I also replaced the ignition coils. When I first got the car it ran on starter fluid and stalled after 5 miles at a stop. I am about to hook up a OSBD1 cable to check the error codes with ECULink. One big thing I noticed is fuel is not entering the fuel rail, it stops right past the fuel filter and will not go up into the fuel rail and to the injectors. I pulled the pipes later on down the fuel rail from the filter and they are bone dry, no liquid. The fuel pump was replaced and that is how I got the vehicle to run on starter. Any suggestions on what to do next? Anything I should check for with ECULink? I am considering rewiring the harness and putting OEM fuel injectors in, which will be $600 or check the physical ECU for damage, leaking capacitators.

Thanks all. ]]> 300ZX (Z31) Forums magikal55 https://www.zdriver.com/forums/300zx-z31-forums-8/help-car-cranks-but-wont-fire-44002/
