4.0 won't start

[Tburercomanche]

Alright it does it more before I go to work in the mornings. I'll get in it try to start it and it will act like it's going to start for a second then stalls. And if I screw around trying to start it for a minute it will start and I'm on my way. Is it the fuel pump? Injectors?

Could also be a low voltage on your cps! a loose or corroded cps connection. Also have you did the Cruiser Tips?

Make sure your fuel pressure is around 39 with vaccum off the fuel pressure regulator and with vaccum on 31 psi. If you have low pressure it could mean a failing pump or a bad regulator with a possbile loose or corroded wiring!

With Cruisers tips you refresh the ground connection behind the driver side rear break light. Many other things it could be too. Tune up could be needed as well?

Try bypassing the fuel pump ballast resistor, white ceramic desk shaped like the Alamo on the driver's inner fender. Jumper between the two wires.
