^^The inertia switch is wired in series. In other words the current flows in one leg and out the other. ( -----> Switch ----->). The answer is Yes you will only have voltage at one wire on the plug when the switch in unplugged. When the switch is plugged in you should get voltage at both...

Success!!! I just wanted to send everyone a thank you for helping me diagnose the problem. My last test at the inertia switch and at the fuel pump harness plug confirmed that the fuel pump was dead. Special thanks to DeRocha for clarifying the voltage issues when I was doing my testing. The...

If I test both sides this will also confirm that my switch is good. I could also use the ohm meter across the switch if I disconnect it. I was not aware that after 2 seconds of > 0 rpm the volts drop down to ~7v. I also was not aware that I had to test the wiring for 12 volts when the key...

I got underneath the car this morning and found a plug above the passenger rear axle. I am guessing this is the fuel pump connector. I took a reading at the pins and one pin had 8.5 volts and the other had 7.5 volts. My diehard battery is low down to 11.0v. Why am I not getting at least...

Ok I got the car towed home tonight. I checked the emergency cutoff switch and it was not deployed. I pushed just in case. I would like to test it. Can I unplug it and use a ohm meter and check for continuity? I do not hear the pump wind up when I turn the key to on. The check engine light...

I will be checking it today. I couldn't find it in the car and I knew it had one. The sticker under the hood told me so. No passengers in the car though. What are the chances of the emergency switch going bad.? Thanks for the location hint.

The road noise is so loud I couldn't hear a thing. When I get back to the car I will try and listen to it again. I will check to see if the check engine light (CEL) comes on with the key on engine off (KOEO) Thanks for the definitions as I am new to the abbreviations. I will check for...

Well it was bound to happen. After fourteen years of use and over 250,000 miles my 94 expl. left me stranded. Out of nowhere with no warning I couldn't get her to start after work. Things I have checked before it got dark. There is fuel in the tank Engine turns over but it won't fire...
