I recently purchased a T-500 HPOP
to replace a tired stocker with 212,000 Miles. The truck started and ran fine (minus a little low on power) prior to the HPOP
swap. Now I cannot get this truck to start and am about to rip my hair out. About 6 months ago I took the stock pump our and resealed it and had zero issues getting my truck back on the road. That being said this is what is going on.
Truck cranks over with no sign of even wanting to start. It just cranks and Cranks. No white smoke out the tail pipe only after I crank on it for a very long time will I get a very very light smoke.
I have checked, double checked, and triple checked my work and everything has been installed correctly.
I have even completely started over and removed and re-installed the HPOP
just to be sure everything was done according to procedure. The Drive Gear bolt is torqued down to 95-100 FT LBs.
I have no way to check duty cycle but did have a spare known working IPR
that I swapped just to be sure- Same results
is installed, torqed to spec, Tin nut nice and snug, and harness is plugged in, No I did switch up the IPR
connector with the Turbo pedestal one.
I tried starting with ICP
unplugged with no change in results.
I hooked a manual gauge to my ICP
plug port- ICP
pressures showed 0 until about 4-6 seconds after cranking, then pressure would slowly climb up to 350-400 PSI
. Which I know Is lower than needed to fire.
I also installed Riffraffs HPX
at the same time- I have literally cranked this engine over for problem 2 hours total cranking time- recharging my batts multiple times and blowing up one starter (it was well over due and giving me intermittent issues prior to this whole mess.
was replaced about 2 months ago
sensor and pigtail replaced about 3 months ago
is only about 3 months old
Injectors have had all orings replaced about 1 month ago
Brand new fuel pump
Brand new fuel spring
Just had a CCT and buzz test performed by two highly regarded shops in my area, both passed with flying colors on the injectors.
I really hate to say it but this has consumed the better half of the last 4 days and I am really frustrated. I know these pumps have a good reputation with minimal failure rate but I am beginning to think I may have gotten a DOA pump.
Do you guys recommend trying anything else before trying to get ahold of Joey to look this pump over? I have reached out to him several time for advise with no response. I need this truck back up and running asap.
