3.4 starts then dies immediately

My 3.4 engine starts the dies immediately I change my fuel pump and fuel filter it still does the same. Any help

 

Look for loose grounds. Check if it runs with the maf unplugged

 

Check the fuel pump circuit opening relay.

 

When I hold starter fluid in the intake it stays running as I stop spraying it it dies

 

Okay, so, what other fuel system tests/checks have you done?

 

I checked if my fuel pump was turning on and it was and I check if I was getting power to my fuel pump and it is any other tests and checks that I need to do

 

I checked fuel pressure and it good so what else I have to do

 

That would mean it's not getting fuel.

If you've checked your fuel pump, filter, and verified fuel pressure at the fuel rail, and that the regulator isn't doing all pressure off the rail, then it's going to be an ecu or fuse issue because then ALL your injectors aren't firing. Either they're unplugged, or the ECU isn't powering up.

 

Just had this happen on another taco. It was a bad MAF
