Super frustrated....AGAIN!!! Truck is hard to start.

Before you get into this too far, change the fuel filter on the passenger side frame rail. Cheap & easy. It may be what's lowering the fuel pressure.

Thanks bro, I had that planned, but I was trying to plan out plan B in case that didn't work lol

Anyone know where the test port for fuel pressure is?

Dr side rear of the intake.

Thanks, I'll have to look again, even though I can't do crap till tomorrow. I was convinced that it was the FPR, but after reading a lot of different things, I'm back on the fence on whether its that or the fuel pump again

Any ideas why it started running even worse when I changed the fuel filter??

The regulator? It kinda make sense that its getting too much fuel.

One question.. do you have a K&N filter on this truck?

Also the map senser can do what your saying also.. hard starts then running crappy..
