Engine Cranked then died and now won't start

[bhackney]

I have a 91 mustang gt that i daily drive. I went to go crank it up and it started just fine like always and after 30secs of letting it warm up, it just died and wont start again. It cranks and has fuel pressure. Any ideas of what could cause this? Im thinking the coil went bad?

Here is a check list that will keep you from spending money needlessly

Cranks OK, but No Start Checklist for Fuel Injected Mustangs

Cranks OK, but No Start Checklist for Fuel Injected 5.0 Mustangs model years 1986-1995 A word about this checklist before you start: it is arranged in a specific order to put the most likely failure items first. That will save you time, energy and money. Start at the top of the list and work...

i replaced the coil and tfi mod. they were both about $40 bucks , could have saved money if i used the checklist.
but i daily mine and they were old as .

How do i test if the coil is bad?

Easy, pull coil wire from the cap, hang on to the end and crank the engine.
You'll know if it's working,
Unless you die, then it don't matter.
Pretty funny to watch but seriously don't do it, you really could die.
just lay the end near metal and look for a spark, factory coils rarely go bad but
the checklist covers this I believe.
First thing on the list iirc is check for codes.
You have to be methodical when you have issues with efi systems, rarely just swapping parts fixes things,

I have a mega squirt so i don’t have codes and the coil i have is a msd one
