Default 94 Mustang GT won't start???

So I am leaving wal-mart and my car stalls, after that it won't turn over, after I got situated I checked for spark, and definately don't have spark, not even getting it from my ignition coil, swapped a diff coil I had lying around hoping for a quick fix, but no luck.

From what I read I think, key word think it's either my tfi (ignition module) or my dizzy pick up.

Any further help into the right direction would be great, I planned on testing my tfi, but it's a hour and a half journey to get it done.

Thank ahead of time for anyone that can help, man first time my car left me stranded since my alternator went out.

Just an update, I located the tfi and took it out the heat sink. I am hopefully gonna get it tested at O O O O'Reillys tomorrow... Kinda hope thats the problem it'll be 80 bucks and plug and go... Dizzy pick up would be a little more work and I would prolly need some help.

Does it sound more like one or the other?? Or even something completely different?

Well here is an update guys, I tested the tfi and it tested bad, so I was kind of relieved to find the problem on the first time, went and bought one from ford and plugged it in the car hoping to hear her fire up and it didn't so now I'm kind of frustrated cause now I'm throwing away money on parts I don't need.

Anyways anyone have any advice? If you need more info please ask??

hey man, i went thru the same thing, except i did dizzy first, tfi module, then ignition coil.

Turns out the pickup in the dizzy (hall effect sensor thing a ma jig) was part of the issue. as the dizzy rotates, the pickup outputs a signal to keep the fuel pump running. if the sensor is bad, it wont run.

if you have the key on, rotate the dizzy by hand while its still plugged in, you will hear the fuel pump run if the sensor is good. you may have to pull the dizzy out to do this so you can hear the pump prime, but better than spending money on a dizzy you didnt need...

Good luck!

PIP Profile ignition pickup. Take the time to properly test the ignition system and money will only be spent on the item that will effect a repair. Bubba
