this is the story. 1987 ford mustang 5.0 5 speed
my car started acting up last week. it would drive fine then it would cut off while i was driving, so i took it to my homie to take a look at it (he owns a shop) he said it could be my map sensor, Ignition mudule, burnt spark plug wire, etc. basically something electrical.
a few days ago it shut off on me but didnt start back up. i tried to compression start it (it is a 5-speed) and that wouldnt work, so i walked to kragen to get some spark plug wires, distributer cap, and rotor. after i changed the burnt wire and it wouldnt start. so i changed the spark plug wire connecting to the ignition coil and it started right up.
After all that i got home and now it doesnt start AT ALL. i think the problem is the ignition module, or the ignition coil,
IS THERE ANY MORE ADVICE? i already ordered an ignition module from summit racing today, please help me out it is my only car right now and i have to go to work, thanks ![[Confused]](confused.gif)

Turn the ignition to the ON position and listen to see if the fuel pump is running. If you don't hear it then that's probably what it is.
My dad had a similar issue with his '89 GT. Turned out to be the TFI module.
EDIT: If it's not the fuel pump then I would test to make sure you are getting spark. You can buy an in-line spark tester for a few bucks. This will help you isolate it down to fuel or spark.

yea check the TFI, also the starter relay it can give you intermitant problems when it goes out.

had a similar problem with my 91 GT. you're just going to have to check all common problems. 92stanglx was right, probably replace the TFI module, same with checking the fuel pump. Replacing the starter relay is worth a shot too.

TFI control module and starter relay would most likely be the bad ones. I have had this happen a few times with ford cars and trucks. Change those two and you should be back in business.

Ok, have you actually checked for spark? It might be a good idea rather than throwing parts at it.
When you installed the TFI module, you did use the correct insulating sealant, right?

Well, you COULD pull a plug wire and stick it on your tongue, you know, like checking 9 volt batteries. Just have a buddy crank it over...
Sorry, couldn't resist. But hey, if you DON'T have spark, all is cool. (Really, please don't do it this way...)
Seriously, a quick test is to pull a plug wire, slide the boot up a bit if you can, and hold the exposed terminal close to a piece of metal on the engine. Have someone crank it over. You should see a fairly bright arc of electricity. If you can't slide the boot up, use the end of a screwdriver to touch the terminal up in the boot, and hold the exposed shaft closed to metal on the engine.
You don't have a pacemaker, do you?
TRY NOT to touch the metal yourself. It'll hurt, but it shouldn't kill you....

Actually, no. If there is no fuel pressure the computer cuts spark. No sputtering. Mine would drive down the road fine, and just shutoff. After a few minutes it would fire back up just fine,
Anyway, when you turn on the key, the pump runs for a few seconds until the system is pressurized, and then shuts off unless you start the engine. One way to check for a bad pump it to turn the key on, but don't start the engine. If the pump just keeps running, it's bad. It should shut off after a few seconds....
