1995 5.0 just cranks

[9GT5]

I bought a 95 Gt Automatic a few weeks ago and it was running at first but had an idle surge. While trying to get the figured out I started for the first time one day and it died within 10 seconds and hasn’t fired back up since.
I hear the fuel pump prime and am getting fuel pressure
I used noid light injectors are firing
I have spark at coil and spark plugs although it does seem a little weak (small orange not blue)
I used continuity light at coil to test Tfi it seemed good
I’ve tried adjusting the timing and did a compression test
My cel lights up when I turn key on and goes away while cranking
The only code I get consistently is 327 (egr valve) which previous owner removed
I’m lost at this point what is the next thing I should be looking at?

Cranks OK, but No Start Checklist for Fuel Injected 5.0 Mustangs model years 1986-1995

Start at the top of the list and work your way down. Jumping around will possibly cause you to miss just what you need to see to find and fix the problem. Don’t skip any steps because the next step depends on the last step working correctly.

Revised 26-Jul-2017 to add fuse link diagram.
