Who knows....?!?!
Hey! I posted a topic here a couple of weeks ago telling of how my stang broke down and when it did you could hear the fuel pump running continuously, and I got replies to try the fuel pump relay or regulator. Well, I replaced both and it was running fine for the past three days and then tonight I was driving along(just cruisin' not messing around!!) and the engine cut out big time for about 2 secs and then went fine for about four miles, then did it again going around a corner for a couple secs. Just the engine, the lights stayed on, so it seems that it was just the engine that went dead! I can't figure this out... I have brand new injectors, fuel pump, regulator, relay, and the filter is probably 8 months old. And a full tank of gas! Could this problem be related to something other than fuel? Any guesses, or anything would be greatly appreciated, I'm at the end of my ropes!! Thanks, you people are a great source for answers and experiences!

It would be quite a bit of work, but hey! Drop the tank and check the connections at the pump. Chances are that is something that you did (or didn't) Sure hope you get it either way

Someone told me maybe it could be the ignition module, on the front of the distributor? Has that ever happened to anyone? Could a malfunctioning module make the car die every now and then? It runs great most of the time but every few days or so the engine will cut out and sometimes it will last a couple of secs and other times a few minutes?? Any thoughts??!! Now every day I drive it to work just waiting for it to cut out! Thanks!!

Thats interesting Mustanguy. Thanks.
Joe, Are you still having a problem with the pump staying on. We put a cam in a buddies car one night, when the distributor was dropped in and fired every thing seemed ok. We shut it down to adjust the timing, when the distributor was turned past a certain point counterclockwise, the fuel pump would turn on while the car was off. Never seen it before, but it seems it must have been something to do with the TFI when the harness was moved. |

Well, it hasn't died for over a couple of seconds since last time, but it has done that before. Although it would stop when the key was turned off! Very strange! B.t.w. I read through all of the t.s.b.'s on that site and I think I may have found answers for some other little problams I may have! Thanks for the help in my dilemma!!

Joe, I've had similar problems and mine turned out to be the module on the distributer, just like mentioned above. Mine would cut out occasionally, and then be OK. Finally, one day it backfired really loud and then died. That's the only time my 92 left me stranded on the side of the road. It was very hard to diagnose, but once the problem was found, it was back up and running great.
Good luck! Trace |

Has the ignition switch ever been replace on your vehicle? The symptoms you describe could be due to this. There was a recall (95S28) where it would be replaced free. If you are not sure if your vehicle's switch was replaced, any Ford or Lincoln-Mercury dealer can look up your VIN to find out.

Sounds like the TFI module to me also.. very common on the Fords.
You may want to check your computer sensor ground as well.. because if that ground goes bad, the computer will start using any ground it can to make the car run, and that includes the TFI... I've repaired a few where the computer ground went south and used the TFI as the next best ground, heating it up and making it fail... checking the ground is easy to do.. if you want to know, email me or respond to this post.. take it easy ------------------ '89 LX Convertible AOD Baumann Shift kit, A+ Servo, B&M SuperCooler, 4.10, Auburn, Moser 31sp, pullies, Poly bushings, KB Chassis kit, Dynomax, FMS aluminum driveshaft, T/A girdle.

Well! Thanks guys, for your responses! Guess what I'll be doing on my day off tomorrow!! Your help is always greatly appreciated! Should I just get a stock module, or one of those "dynamod's" I see in magazines?
Wrencher, how can you tell if the computers ground is bad? I chaged over to mass air but this has been happening before I changed! |

go to the EEC test connector and look at it as if it were a house, and the pins are windows.. the upper-most (second story) right terminal is the computer ground. Take a dvom and hook it to this terminal and to battery ground. you should see less than 200mv or .2 volt.. if its anything above that, then you have to start diggin.. if its lower than that, you're fine. Good luck

Hi Guys,
I just got back from APEX Motorsports in Santa Clara, Calif. where they diagnosed my 95 Cobra with a bad distributor ignition sensor module. I had the same cutting out symptoms as you guys. AT first they thought it was the TFI module. They replaced that and the car was still not starting, then they replaced the distributor and the car fired right up. I wish I had seen your emails earlier. They gave me a loaner distributor so now I need to decide which brand of distributor I should get to replace my old one. I am now wary of buying a stock ford distributor. Regards, Burgie 95-Cobra Quote:
