So you have fuel pressure.
And it runs with starting fluid - which is basically fuel delivered with the air intake rather than through an injector.

And you say it progressively got worse.

Could you have water in your gas?

If not that, I'd pull an injector or 2 to look for blockage of some sort.

we pulled driver side bank off yesterday they looked good but cleaned them anyway no change

It starts up on its own then dies we tried starter fliud and it kept it running

Explain the conditions under which you checked the fuel pressure. And where and how.

Basically, I'm curious to see if you're getting good pressure at startup but the pressure isn't maintained.

Did you physically remove the fpdm and look at the back for cracks?

radding42

Checked pressure up at fuel rail and also back pressure underneath' took fpdm off truck it looked like new on cracks ect

Wow. I got nothin. If it were me, id check for vacuum leaks not expecting to find any. Then I'd clean the throttle body knowing that probably wasn't it either. Then I'd tow it in to a shop.

The low oil pressure thing is bugging me.

Good luck dude. I'll be watching to see how it works out.

Might be worth putting a light on the injector pigtail. The injectors should have power to them all the time and the PCM switches the ground on/off. If the injector is firing the light should flash on and off rapidly. Try searching around for making a light tester.


Change the fuel filter?

Injectors were checked yesterday and fuel filter was changed monday. still at a loss

Any luck? Have you checked fuses?
