Well I am back...I thot it was fixed but after i drove a friends truck like mine I was very upset!!! I HAVE NO POWER!!!!! His truck was all stock and would just fly compared to mine. I did have a problem with the injectors at the time of this first posting but now I have a problem with fuel pressure again. With the TECH II connected driving down the road it runs good up to about 1/2 throttle and then everything after that is down hill. It calls for 23000,psi and the actual drops from 13,000 to 3,000psi. Some say the pump and some say the regulator. So anyone got any ideas?

 

how many miles are on the truck and when were the injectors replaced?

 

160000 and about 6 months ago the injectors were replaced. It drops pressure after 13,000 psi or so. And it drops all the way to 3000psi.
