As some of you might know Ive had a p1093 and P1094 code for about a year and a half now ( low fuel rail pressure at idle and accel.). Recently I purchased a PPE standard Xcel. and Im loving it. We recently did injectors on my brothers 02 dmax and it runs great. So last night, I had my truck set on level 5 just screwing around and I told him to get in his truck, and see if he could keep up. He was behind me and from a dead stop we took off. He was on my @$$ the whole time!. I turned to home and he headed his own way. When I called him he said he had to let off because he was getting too close to my bumper. I dont know if he was kidding or not but he was right on me. Does this sound like and injector pump or FPR or both? yes, ive changed the fuel filter, and yes ive had the injectors checked. Dealer said injector pump, but we all know how they are.
