So my engine isnt getting fuel. Replaced all fuses, checked all lines, and realized that the fuel pump relay isnt getting power, so i decided to hook the fuel pump directly to the battery of the car. Fuel gets to the lines next to the engine, tested it by turning the fuel pump on into a cup and it filled up. Could there be a reason that the engine still isnt getting fuel? It starts on starter fluid, just wont start normally. Im thinking its the injectors either arent getting power or theyre all clogged.

 

Connect a scan tool, look at the data stream. Verify that the computer has an RPM signal. IF (big IF) you have an RPM signal, do you have both power and intermittent ground at the injector harness connector? (Does a "noid lite" flash?) The injectors should have power whenever the ignition is "on". They get pulsed ground via the computer.

No RPM signal, the computer won't turn on the fuel pump except for the 2-second "prime". No RPM signal, no injector spray. However, the pump should run if the engine is cranked long enough to build oil pressure. Still won't get injector spray if the computer doesn't see that RPM signal.

If there's no RPM signal to the computer, the problem can be with the pickup coil including the magnet on the distributor shaft (common problem), the ignition module, the wire harness that connects these parts to the computer, or (rarely) the computer itself. Given that the engine runs on starter fluid, the pickup coil is probably OK, and at least some of the circuitry in the module is working.

I've also seen injectors that are stuck with varnish. Sometimes they clear up on their own, sometimes they need replacement.
