Re: 94 Ranger No Fuel cont.

Terry, unfortunately it got dark to quick tonight, but here's what I was able to accomplish tonight. I plugged and unplugged the PCM plug a few times with no luck. However, I went back to the injectors to see if I was mistaken about the pulsing. When I turn it over the light gets dim and I thought that I saw pulsing, but now that I look at again I don't think that there is a pulse. Should the pulse be obvious? Since there appeared to be no pulse I went to the crankshaft sensor with my test light. I hooked up the test light to ground and checked both wires at the crankshaft sensor, no power on either wire. Should there be power to one side? Or does it work on a ground basis to where I should have my test light hooked up to the positive side of the battery when I check the wires. I also checked the red wire at the PCM relay that feeds the ignition control module and there is power. I looked for the ignition control module to check to see if one of the two wires that go from the ignition control module to the crankshaft sensor have power but I can't find the module. The manual says that it is supposed to be on the fender well. Do you know where it might be or am I on a wild goose chase? Also, would a lack of signal from the crankshaft sensor keep the pump from coming on when I initially turn the key on or could I be looking at two problems? Thanks for all the help. I am determined to try to figure this thing out.
