I don’t believe it would start if the tfi were bad.
Plugs n wires new I assume?

5.0 monster computer problems
So I'm have some real hesitation and power loss from my 95 5.0 oh. I can't tell it's definitely a computer issue. Everything turns up good with all the new senors. But I suspect the tfi on the passenger fender is going out. When I finally got the specialty tool to unbolt it. I had it tested, and it checked out good. But while trying to find the tfi, I ended up redoing my timing. And it worked as good as new. For all of about 3 days. Now it's doing it worse. And it's not out of time. I assumed it was just out of time but I'm suspecting the tfi. I need some serious help I've been trying to fix this problem for months now.

MAF new? Engine coolant temp sensor new? Iat new? Maybe it’s seeing something new it doesn’t like and is pulling timing.
Or is it fuel pressure related?
It’s mega hard to diagnose via the web. Too many things cause the same symptoms.

IAT- intake air temperature sensor. It’s located in the pipe/tube between the filter and throttle body. I’m 98%.6 it’s not the tfi. With a bad tf you’d be driving and the car would die. Also, it tested good three times.. You have something intermittent and the tfi is coincidence.Yes. Has new map, new o2 sensor, tps, distributor, wires, plugs. What's lat? And I think something is pulling timing. Fuel pressure seems good.MAF new? Engine coolant temp sensor new? Iat new? Maybe it’s seeing something new it doesn’t like and is pulling timing.

The only reason I think it's the tfi is because when I took it off and had it tested. We tested it 3 times and each time it tested good. I bolt it back on and it runs good as new. 3 days later. It starts spitting and sputtering under any sort of load.
You tried to pull codes and got nothing?
The engine coolant temperature sensor is pretty important also.
