'95 Cobra stalling

Have a '95 Cobra, 5.0, 70,000 miles on it which has developed nasty stalling habit. Drive for a while, then it stalls and I have to let it sit and cool down before it will restart. Stalled twice on way home from work tonight in

91 degree weather. I finally ended up driving it home with the hood partially latched to increase the air flow over the engine. Is this the TFI module overheating problem I've read about? Will replacing the TFI solve it? Any other thoughts on this? Thanks, Dave

hmm unlikely since the TFI on the 94 and 95 was placed away from the distributor (under the airfilter if I recall correctly) You can try replacing it, but my guess is that it is the HALL effect sensor inside the Distributor. I had the same thing on my 95GT. It started out with having the car stall after driving it for 5 miles or so. It would stall for 1 or 2 seconds and then drive fine again. While it would stall, ALL gauges on the dash would drop back to 0, even though I could still hear the engine make rpm's (manual) This went on for a week or so and then it got worse. I started the car and it would stall after 20 seconds or so. Had to cool it down, it would start, same thing, etc.. Dealer changed the sensor, cost about 300 bucks. The pinging under load also disappeared after they did the repair.

Thanks, Rein Yeah, sounds like my problem alright. Isn't the HALL effect sensor part of the stator in the distributor? Or do I have to replace all of the connectors, magnet, PIP sensor, etc. Dave

I'm not exactly sure, I thought that was the same thing (hall-effect/stator) ?? I could be wrong. Anyways, from what I heard, you need a press to fix it. It cost me around 300 bucks at the stealer. I think mine also went around 70K miles...yup, at 62300 miles (still have the records.)

Did it do the shoirt-stalling like I described before it did this ?

good luck.

Yeah, it would cut out for 1 - 2 secs, and then be OK. At the time I chalked it up to bad gas, bad karma, bad shift, bad luck, impending doom, whatever. So, I'm taking it to an auto-electric specialist shop on Monday. He agrees that it is either HALL effect or TFI but probably HALL. Had a face-to-face with him yesterday and he says he has had experience with this type of thing on stangs and he seemed to know what he was talking about. At least he knew where the sensor was located and asked me all the right questions, like what's the balance in my checking account. I guess I trust him as much as the dealer (stealer, LOL.) I called Better Business Bureau about him, said there were no complaints. I'll post a reply to this group on Monday, or Tuesday, or Wednesday or whenever he fixes it and hands me back my wallet. Thanks for replying, Dave

Dave,

Playing a hunch here, but I'd BET it's your electric fuel pump. My old 5.0 LX did the same exact thing. The pump would get hot, cut off, and the engine would stall out. I'd let the car sit for 30 minutes or so, the fuel pump would cool off, and the car would start right back up.

Is the stalling due to over heating? You don't say so in your message!

overheating

Again Dave there is not enough info to go on! When does stall out occur? During stop and go traffic? During sustained idle? It could be many things which guessing will not help you.

Patrick, Ford fuel pumps are designed not to overheat! Thats why their design calls for them to be installed inside the fuel tank! If anything it may be the fuel pump relay switch that senses heat overload from the engine and shuts off the fuel pump to prevent explosion.

Okay, I used the wrong choice of words. Let me say it this way... I'll bet his fuel pump is wearing out.

Well, the auto electric shop had the '95 for 2 days, drove it all over town, used a 1/4 tank of gas and couldn't get it to stall! This was after they went over the engine and made sure every connection was tight and that everything was where it was supposed to be. Ran the diagnostics twice on it after driving and no problems were showing. They're giving it a clean bill of health! I don't know if this is good news or bad news - Time will tell.

Housemanx,

I'm telling you... I'll bet money it's your fuel pump. My old '87

5-liter LX did the same exact thing. It stalled out then later restarted a few times (and months apart) before I finally figured out it was the pump. The second to last time was on a trip to Colorado. It cut out on me and then later restarted. So I drove it into a town in Colorado and they replaced the ignition module suspecting that was the problem. Afterwards I drove the car all the way back to New Mexico without a hiccup thinking my car was fixed, only to find out a few weeks later it wasn't fixed when it cut out again. I then changed out the fuel pump on a guess and BINGO the problem was solved. I never had it cut out on me again.

Betting 10 bucks it's fuel pump,
