I've replaced the fuel pump two times the first time I had a mec. Do it the sec. Time I did it my self I didn't. Have 600 buck to spend so I don't know? I replaced a fuel pump regulator on an older for when gas was coming out of it not sure if that's the problem this time

 

looks like your down to that.. You've replaced every thing else..

 

Yea. I know

 

Regulator is a lot cheaper and easier to replace than the pump.

 

Replace fuel pressure regulator and pressure stayed the same what do do now ?

 

Could it be the EGR Valve. Sticking?

 

You would get an EGR code.

 

What do I do next intake gasket or anything I missed?

 

if i were you i find a diagnostic expert and let him do his thing..

 

Well I replaced the two lower oxygen sensors and reset the computer again. The light has stayed off for almost a week. Read the truck again and no codes! Truck is fixed finally! Thanks everyone for ur input!
