Truck won't start

[Nic]

Hey all. I have a 91 ranger, 4.0 and it was giving me fits last night...seemed like a nasty throttle issue. So I go to work on if this morning and now it hardely starts and when it does it dies about instantly. So now I'm here beating my head against the engine trying to figure out what's wrong with the damn thing. The linkage isn't blocked or anything, I was thinking maybe TPS?

more info would help. can you keep it running with your foot on the gas. does it try to start is it just not firing.

Even with foot on gas, it still dies. Checked the injectors, they aren't getting power. So now the question is, why? Starter fluid helps and makes it run for a few seconds, but then it dies.
Thanks.

check your connections/plugs for corrosion. injectors ground through the ECM i believe..

I did that, no luck. The only thing left I haven't checked or replaced is the main brain. I'm calling it a night, I'll do it tomorrow
Thanks guys
