Need some help with my 2.3..

Picked up a 90 2.3 LX I wanna do a swap someday but for now I just wanna drive the hell outa it..

Here's my symptoms..

She's really hard to start.. Seams like it starts and dies starts and dies instantly..

Once it starts. It will idle kinda high 1100 range
It will slow down a little bit 950-1k

The biggest problem is if you hit/step on the gas.. Poof it dies.. It will do this over and over and over again..

But what gets me is it idles wonderful.. Purrs like a kitten.. When it's running.. So, I'm thinking a fuel pressure regulator? Maybe idk, I have no idea......

Any help would be wonderful...

I'd definitely start checking fuel. Fuel filter for sure, fuel pump relay, and fuel pressure at the rails for sure! Start of easy and work your way up. Could be something simple, and it could be a failing fuel pump or an electrical issue but rule out the easy stuff first.
