I am testing these voltages at butt connectors I used when I replaced the connection to the fuel pump. Wal-mart,Any local audio store, etc. If so, remove those as well. I haven't really looked to see how comprehensive they are, but I believe they are complete. Haven't done this for a couple months but there may be four additional nuts behind the ones you just removed holding the digital display in place. B - 30 Amp Main-2? And some say this is progress? If you are looking for the formal Wiring Diagram.
Not only that, … but usually you have to get them through the manufacturer's publishing contractor. Repair open or high resistance in Black wire between starter relay coil ground circuit cavity No. An inoperative fuel pump relay can result in long cranking times, particularly if the engine is cold.

Unplug all connectors from the electrical units containing your headlamps, etc. This also passes through the neutral safety switch.

There is a car stereo adaptor that you can buy at any place that sells electronics, i. What can I try now? You said you replaced the park neutral switch? I charged the battery replaced the connector at the pump.
When trying to crank the engine is there battery voltage there? A - 60 Amp Main-1? Depress clutch pedal and move shift lever to Neutral. If engine cranks, go to step 20. Otherwise I will build hi head psi on compressor. Hopefully the one you need will be in there. There is a 175amp fuse that supply's battery voltage to the power distribution center - fuse box under the hood.
My hoist hit me in the head! Locate and disconnect starter relay. You can get free automotive wiring diagrams at Freeautomechanic. I discovered that the system is actually designed to do that! Earlier you said you got power for 2 secs at the pump-that's all you got before the relay de-energize-it should turn the fuel pump On for that 2secs. It then transfers control of the fuel pump to another relay. Im working on unhooking my battery cables.

Mar 29, 2016 First you need to raise the truck off the ground and put it on jack stands. Thanks fixed As a followup I have found the problem. Long cranking time will not lite at pump, so Im thinking problem is after relay and oil switch connection or one of them would cause lite to lite. With vehicle running, voltmeter should indicate less than one volt. Since a long cranking time doesnt power it either, the problem is somewhere after the two are connected.
The relay works as I probed behind it on the terminal for the gray wire which is the hot one for the pump. Is there another relay that I need to check? I did go from a 5 speed to a 700r4. Ac will run thru circuits only when fans run. I am about to lose my mind and job. Make sure you get the information you are looking for.
