You should really have a full time fuel pressure guage in the cab.

Have you had a chance to check for codes?

 

i may have missed this, but are you running on the stock lift pump??? if so, your situation is identical to when my 98.5's lift pump went out, i had no throttle and hard starting, it just ran like crap. before replacing that expensive VP44, get you a fass lift pump at the very least a 95 gph one. they run around 400 bucks but are well worth it. I thought on my 98.5 it was the VP44 and once i put that fass pump on it, the problem was cured.

nice looking rig btw

 

his sig once said he had a Holly pump?????????

 

im not a fan of holley pumps, i burnt through them almost as fast as i did with stock lift pumps, dont try BD's lift pump either, there junk, mine went out in 4 weeks, 800 miles. thats why i went with the fass, yeah its louder, but man i can mash it with my sticks and the PSI not drop below 14

 

RJ818, what did you find?
