Hey Jeff K or any other wiring guy...

Thanks for the advice on the fuel pump on my car. I followed your instructions for testing the pump directly and the pump came right on--squirted fuel everywhere in front of where I have the hose disconnected from the filter. So the pump, its ground, and the connection on top of the tank are all good. Still no go on starting the car. Do I need the inertia switch? I realize it's a safety device and is supposed to be there, but can I get by without it. Would the system work if I just twisted the wires from the intertia switch together? I don't want to blow anything up, but I'm desperate to make this car run. I don't have a test light to check the function of the inertia switch but it shows nothing on my volt meter. So what's my next step? How about bypassing that intertia switch, possible? Thanks again

Okay, I've got some new info. Like in my previous post the pump, gound, and connector on top of pump are good. Just now I put the volt meter on the wires of the inertia switch (now that I know which one is the hot wire), turned the key to on, and jumpered the #4 pin under the hood with the ground on the negative battery terminal. The inertia switch wires read 12V! Now, I have the click in front of the shock tower by turning the key to on, and by having the key to on and jumpering the #4 pin to the ground. This means it is definitely the inertia switch, right? Or no? What do you think?
Thanks

Kev, I REALLY don't want to sound like a dumbass, and forgive me if I do please...
You DID reset the switch, right? I'm sure you did, considering all the crap you've been thru by now... but maybe?? [Image: redface.gif]

Voltage is fed from the fuel pump relay in the ICM out pin 5 and directly to the inertia switch, then to the fuel pump. Yes you can jump out the inertia sw, BUT I WOULD repl it ASAP if that is your problem.

I will replace it as soon as possible, but for now... I would bypass it by connecting the two wires together that go to it? And yes James, I checked to make sure the switch wasn't tripped. Man would I feel stupid if it was something as easy as that! Thanks for looking out though.

Yep, you can connect the two wires together to see if that is your problem.

Yep, I connected the two wires together at the inertia switch and it fired right up! Since all inertia switches on fords are the same, (right?), I'm sure it won't be hard to find a replacement. Thanks for everyone's help. I think this is the first time my bird broke and I fixed it (although temporarily), for free. Thanks again

Yes, all Ford inertia switches are the same. They are made in England (home of Lucas electrics [Image: frown.gif] ), and therefore are prone to failure. My inertia switch went intermittant several weeks ago, and I know 2 other people who have had inertia switch failures in the last year or 2. If you go to the JY looking for one, be aware that Ford hides them in way different places in different makes / models.
