I'm looking for a '87-88 T-bird/Cougar sending unit for digital cluster. For unknown reason circuit board broke in half inside the float cover in my '87 Continental.
It got a little warmer here (around 40F outside and 55F in the garage vs. 15-20F and 30F for last month) so I got back to work on the Continental.
I've replaced the air-suspension controller today and it fixed all the suspension problems (eg. one ground output gone), so I guess that good EEC will fix missing ground to the inertia switch.
Yup, the wire grouded in the trunk is tan/light green. I'll try to pull the EEC tomorrow and will post a pic here. I think you're right that T-bird or Cougar EEC may work.
All the Fox-Continentals were V8.
BTW. Is it possible that all these trouble are resut of welding something in the car with battery connected?
test the relay it should have 4 wires the relay has two hot's "+" and one ground and one that is ran to the pump and the wire is hot only when the relay is powered if you find the hot's and you get power with the ignition on one wire is the ground and the other is dead till the relay is powered most likely the ground on the relay will be a small gauge wire i don't have the colors of the wires on hand.
find the ground and ground it to the body quick with the ignition on and if it clicks and powers the pump the relay is good the the Inertia switch is most likely bad .. the reason why it won't work right when everything is hooked up factory is because the Inertia switch won't complete the circuit check it and let me know

Hi Nick!
I've done some reaserch today, I found one (+) wire always hot, one (+) hot with ignition ON and (-) which turns out to go thru inertia switch. I measured the voltage and found the problem. Both (+) have correct voltage while the ground is unstable. With ignition OFF I get 12.5V on that ground wire while with ingintion ON I get only 9.5V. That's why "external" ground is helping to get over 12V and power the relay.
What may be causing the ground voltage drop on the wire going to inertia switch? Where is the wire going to inertia switch connected? I found the end goes to the fuel pump realy.
Why the pump is working all the time with ignition ON, not only priming the system?
But if I'd jump two wires going to inertia switch than the pump doesn't work either. It works only with one inertia switch wire grounded. I'll take a pic of this wierd setup tomorrow.
I just got another Fox body car - 1987 Continental Givenchy. It has some issues, like rotted rear brake line, air suspension problems etc. I always wanted to have one like this and it looks like nice project.
I was wondering if I can ask one non T-bird/Cougar but still Fox-body question here?
I can't figure out what's wrong with the inertia switch and fuel pump relay in this car. Somebody grounded one of the wires going to inertia switch and the pump works all the time with key in ON position. If i remove the wire grounding the inertia switch wire and connect everything as it should be the pump doesn't work. When I ground that wire the relay clicks and pump works, what may be wrong here?
What does the grounding the inertia switch wire do? Is is a shot relay?
She's my girlfriend for sure :D I get a feeling I'm posting pics with every new girlfriend here - I hope it's serious this time cos I'm getting old! LOL!
Thanks, it's nice to look like someone famous I heard of this guy, think he was #1 of the year 2007 in local radio station chart, but I don't remember the song title.
Hi Vinnie! I'm doing just fine, but I split up with my girlfriend last week. So I have more time for my cars now ;) My V6 T-bird is doing great and it won't see winter again. I got a Mark VIII in January, so T-bird is a weekend driver now - it's in perfect condition, rust free, all original and complete (with your help :)). I'm planning getting historic plates for it soon (it's so rare here that I can get historic plates before it will reach 25 years). I sold the Turbo Coupe in March, because it needed a lot of work (badly worn out cam, lots of rust, bent pass side sub-frame) and rodents invasion was killing me (what a mess and awful smell inside): http://www.youtube.com/watch?v=A2W48pLQ2X4
