still no start( need help with sct livewire)

[arcticycle]

well i still have not found the problem this is where i am at, trucked died on freeway just shut off first thing checked cps then checked fuel pressure(55psi) pulled codes injector pressure code came up but i cant remember the number seems like 13-somthing then i erased it by accident checked all fuses and swapped around all relays nothing took it to dealer thy scaned and said it was uvc harness so i changed both sides and changed my ipr valve thats wher i am at now i just got my sct hooked up to my computer i ran a few pids but i dont understand them is there somthing i can look for im thinking injectors now but im not sure how to test them/ohms/pressure/power/im ready to give up

Can you do an injector buzz test? If not, take an ohm meter and place one lead on the very center pin of the flat 9 pin connector that goes into the valve cover harness. (unplug this harness near the inboard center of each head). Place the other lead on the two prongs just right and two prongs just left of center, and look for an ohm reading of less than 5. They're usually in the 3.2 - 3.5 range. If you see one or more injectors ohm out at a higher or lower number than the rest of them, you might want to pull that valve cover again.

With that said, it's very unusual for a loose UVCH to cause the truck to die. If you had a P13xx code, it was likely an P1316 IDM code, not a 12xx ICP code. A bad IDM could cause your truck to die.

Can you monitor ICP pressure (looking for 500 psi) and IPR or ICP % or duty cycle while cranking? Try looking at those numbers and let us know what you see. Is there any smoke coming out of the tail pipe while cranking?

thank you for the reply i just got done with this livewire this is what i found / fuel psi is 69.8/ipc duty cycle .40625/icp control psi 573/icp filtered14.9/injector pulse width 3360 this is cranking the motor for 17.12294 sec which was about 5 seconds my time, no sct wont buzz,and as far as smoke i cant really see any but it smells like raw fuel because i have to keep opening the garage door for fresh air but i will check the ohms in the morning

well i ohmed all the injectors and they were 2.8 to 3.0 is that in range ,is it even possible that just one injector wouuld just shut the motor off like a cam sensor failure i guess the only thing else i can think of is the idm, might just head back to the dealer

well it was the idm on the the road again thank you all for the help
