Fuel To injectors, still no start

PM me your address and I can send you spare PMD on heatsink and fuel shutoff solenoid if you want to try that.

Make sure your getting power across the fuel shutoff solenoid (cylinder on top of IP) harness with the IGN ON. And then plug it in and probe the lines to make sure its getting through the solenoid. The power comes from IGN and grounds in the PCM. If you unplug that and crank you should get code 13.

Unplug the crank sensor and crank the enginer and youll get a 19.
And if you remove the Glo Plug fuse you should get a 29. And when you clear everything you should be getting code 12 always. Before you didnt even know the SES light was there, so is it working with IGN ON?

you should be getting codes for OS unplugged as well.

And you made sure the clocking of the crank 12 cam 12 and IP at 6 was correct on the timing.
 
yep on the timing marks, fuel shut off works, i took it out today and turned the key on and watched the plunger go up, yeah its on w/ ign on, but i already did the crank sensor, shut off solenoid, glos, got those codes and then cleared them, tried w/ op unplugged and didn't get any codes for that, well int diesel set the lower timing and put the chain and harmonic balancer on, so i guess it might be off depending on the possibilities of what the crank can be at when cam is at 12, cause i cant see the marks for the crank, but ip to crank is right
 
i dunno im about to give up and take it to a mechanic, do you know if full coverage insurance covers mechanical faults

Nope, only if it happens in a collision. Unless you had some kind of aftermarket warranty.

And your unplugging the OS harness attached to the black circle thing on top of the IP? Should throw some codes when unplugged and if not going to have to figure that out. I think most people get 17, 18, 35, 36 when unplugging it. Let me go see what I get

yeah i unplugged it, cranked a few times, before i did that it sounded like it was trying to fire, then when it was unplugged it didn't sound like it was trying, tried cranking a few more times ran the codes and all i got was 12, let it flash 4 times just to make sure
 
I am in my truck now, using GMTDSCAN to read stuff in real time, and when I just crank (took out Fuel Solenoid fuse) with the OS unplugged I get a 17 and 18, I get the same if I just stat it up.

For the heck of it I unplugged my crank sensor and I cranked a long time and it actually fired up, I never cranked that long before, but at least now I know it will start with that disconnected and a good OS.

Let me look through the books and see if I can figure out why you wouldnt throw a code with the OS unplugged.

Mine also starts up fine with MAP boost sensor unplugged, and I get the 62.
 
Try starting without the engine coolant temp sensor plugged in. If it doesnt help just put it back.

Then.....Pull off the OS harness and try measuring voltage on pin A, the grey wire. Should be 5V with IGN ON.

Then make sure that pin D, white wire is grounding, so if you test it to the battery should be 12V or just test it over to pin A grey wire and there should be that 5V.

This is a little more involved. Plug OS back in. Need to pull out the PCM from behind the glove box and find 24pin Pink pin D9 purple wire. backprobe D9 or that purple wire somewhere (with other meter probe grounded) and with all the harnesses plugged into PCM, crank the engine. You should see 2-3V.
 
alight thanks, i'll do that, if i don't have correct voltage bad PCM? if i do have right voltage then what PMD?
 
except you get some fuel to the injectors. IPs are a little expensive, which is why I'd try all the tests you can do. It sounds more like you have a PCM issue if you dont get any codes with OS unplugged. So if the checks I said earlier check out then maybe I'd consider IP, but I wouldnt replace IP without trying another PMD first.
 
It sounds like you may have a bad crank sensor on top of another issue. It should start with crank sensor or OS plugged in, but you said it doesnt even try without the OS connected.

I have to believe you have a PCM issue. I cant see any way that with the OS unplugged the PCM wouldnt code a 17 and 18.
 
Buddy that is another expensive leap to go with a PCM, and not a common occurance, we are overlooking something basic here, Jason since this thread is 6 pages long now summarize start to finish everything done so far start to finish, begining with engine change to where we are now, list any sensors/major components swapped over, and describe how you set up your timing gear/chain
