fuel injecters in a F150 with 302

Asked by Feb 07, 2011 at 05:11 PM about the 1987 Ford F-150

Question type: Maintenance & Repair

The engine turns over, its getting pressure at the fuel rail, its got spark, the timing seems to be right. I put new plugs,wires, cap, roter ignition mod, ECU and it still wont start. If the fuel injecters are working would the plugs show signs of gas and if not how can you tell if their woking. From what im reading there is a crank shaft possion sensor that sinks the signal to the ECU. Can that sensor be my problem and were is it located. PLEASE HELP ME

you could try spraying fuel in it while someone turns it over (hold the throttle plate open a bit, and use a spray bottle) and see if it'll even start. If it doesn't start its not an issue with fuel. If it does start then you know its the injectors, or injector harness that is the problem.

another way to check if the injectors are doing their job or not is to remove one from the intake manifold and re-attach the plug to it and have a buddy try to start the truck, if you have fuel spraying out of it then they are not the problem.
