so tonight we swaped out all the relays with the one's in my fathers truck. he has a 2000F350 powerstroke and all of them work no problem. the oil is toped off, put in a new fuel filter, checked all the fuses again and double checked the CKS we replaced the other day, and all is good. we went against our better jugment and shot some eathier into the air intake, and to my suprize, it wanted to run, but did not have the fuel to support it. so from the fuel tank to the fuel filter it is getting fuel no problem. my gues would be the HPOP or injectors are not working. but it is only a guess at this point. my queston is, which one of them would stop working first, if indeed it is one of those two things?
