I have a huge problem, i just put a new engine in my 93' ranger and it will not start. I have checked all the wiring and everything tons of times. I am getting spark but no fuel. The injector rail has fuel in it and enough pressure but the injectors are not firing. I checked the voltage on the wiring that attaches to it and both Red and Tan wires are getting a charge. I have spent the last week or so trying to find what could be causing this. I have checked the Ignition Control Module, Crankshaft Postion Sensor, and most other modules or sensors. I would be grateful if somebody would help me out here, because I am getting no where.:icon_confused:

OK, the red wires should have voltage on them. Now for the tan and white wires (two injector will have red and tan, the other two should be red and white), those wires go to the computer, I think its pins 58 and 59. The computer takes those wires low (grounds them), then the injectors open and injects fuel.

Its nearly impossible to check the tan and white wire with a digital volt meter. They dont respond fast enough to change. But it can be clearly seen with an analog volt meter.

If you can locate an analog meter, hook it up to the tan or white wire, set it to read voltage and crank the motor. The needle should move back and forth from 0 to 12 volts.

I figured it out. The mustang fuel injectors either required more pressure then the fuel pump could put out or they were plugged. I put the old fuel injectors of my other motor and it fired right up. :yahoo:

now i get to weld on the new core support and ill be done :icon_welder:
