Ok hey everyone new here need help! Ok to start ive looked all over this forum for answers to my problem but so far nothing :frown2: Anyways I bought this truck for next to nothing $650 :smile2: but anyways the guy I bought it from said it would run but only like 5 or 10 mph and cutting in and out cant prove this he had the batteries out of the truck. Anyways I got it home put 2 batteries out of my idi in her motor spins wonderfully :smile2:! But still no running :frown2:! Ok I have replaced #22 fuse it was blowed so me being bright put a 50 amp fuse in without reading and put the key in the ignition without unplugging fuel bowl heater and fixed the wts issue, but heard some like frying sound under dash or under truck one... no clue what it was, but truck still spins over fine nothing crazy with gauges or nothing! So then began my journey reading on here I read cps could cause no start issue and make the tach not move while turning over, rough idle, and a bunch of other stuff so I replaced nothing! Ok I read about a possible chip issue pulled pcm looked for chip nothing. From there I pulled the fuel filter and looked at fuel in bowl at the normal level and fuel looked good! So I drained the fuel out to see if more would replace it and to unplug bowl heater. Well after putting the filter back in and the turning it over the bowl did not refill! Ok so I know there's a fuel issue as well im not concerned with that yet I really just wanna here it run. Thats when I found out about the cps so I pulled mine and it was rough looking and I replaced it. So I manually refilled the bowl with fuel and turned it over and still nothing. Im scratching my head at this point.... what else could it be?!? Plz help me!!!

Truck also while turning it over no smoke or nothing is coming out the tail pipe if that helps at all. Makes me think injectors aren't firing no clue why though and also after turning it over the fuel bowl didnt go down a drop

What does fuse #22 protect?

Possibly a fuel pump?

 

[Smokin_Strokin]

Yeah I figure the fuel pump is my probs to not get fuel. I'll fix that after I hear her run. My main concern right now is the fact it wont run with the fuel bowl slap full with new deisel fuel. Should run for a few seconds with bowl full I would think considering thats where the injectors get their fuel from. Im getting nothing not even a puff of smoke. And #22 fuse under the hood controls the pcm and the heater for fuel bowl. Wire on heater broke and was touching inside of bowl is my guess to why it popped the fuse.

The fuel pump is a two stage fuel pump on these trucks. It pulls fuel from the tank on the low pressure side and pushes it through the filter. It then takes the fuel from the filter and sends it to the injectors on the high pressure side of it.

It wouldn't be that rare for a truck that has been sitting to have both sides go bad close together.

 

[Smokin_Strokin]

Ok so the fuel pump actually pushes the fuel through the filter to the injectors?

 

[bugman]

It pushes fuel from the tank to the filter, then draws it from the filter and sends fuel to the injectors.

Ill try it its the only thing really I know left to try

Slow down a little...What are you going to try? There are many things that will need to be checked - let's start with the simple, inexpensive, easy things first.

What is the fuel level in the tanks? If the pickup tubes are broken or cracked (as is common), you'll run out of fuel at the quarter tank level.

You need to put your fuel bowl back together and check the fuel pressure as you are cranking the engine.

Use a tire pressure gauge on the Scraider valve located on the side of the fuel bowl.

No pressure does not automatically mean you have a bad fuel pump.

And listen to bugman, he knows his stuff.

Another thing to check is the high pressure oil pump. If you have been doing extended cranking on the engine it may of drained it. The low pressure pump should of refilled it but it is another thing to took at. There is a plug on the top of it that you can remove and check the oil level in it. It should be within 1/2" of the top. The hpop only would affect the injectors not firing and not the no fuel in the filter housing.

 

[Smokin_Strokin]

Ok I've done refilled the hpop with oil tried it still nothing and my fuel bowl isn't disassembled its sitting full of diesel fuel right now with the filter on it. Ive tried cps, starting it with ipr unplugged, fuse #22, pcm, and hpop oil level none of this has worked. What else other than fuel pump can cause injectors not to fire that I haven't tried thats cheap. And ill put a gauge on the fuel pump tomorrow thanks for the imput yall!

 

[ArcticDriver]

Isn't it the ICP you want to unplug? Thats probably what you were meaning but I just want to confirm.

 

[Smokin_Strokin]

Oh yeah tank is 3/4 full I filled it while I was putting fuel in the fuel bowl

 

[Smokin_Strokin]

Yeah I guess its the plug on back of hpop

 

[ArcticDriver]

sorry if I am missing the big picture but if the fuel pump is not working then what is going to push the fuel in the fuel bowl to the injectors? What pressurizes the fuel system?

I see you have said the fuel bowl is now full of fuel but was that because you filled it by hand?

I know you want to hear it run but I think its time to take a breather and do this the right way and not shortcut it. That already resulted in some wires sizzling with the wrong fuse.

 

[Smokin_Strokin]

Idk if the pump is working or not it aint like you can hear it running or anything lol it being manual and all. Yes im the one who refilled it because I know there should be fuel in it I didnt know that it worked off the pump not off of vacuum

 

[madpogue]

The connector on the back of the HPOP _RESERVOIR_ is the IPR. It's a REGULATOR. With the IPR disconnected, you'll never build injection pressure and the engine won't start. Perhaps you're thinking of the trick of disconnecting the ICP, which is a SENSOR on the driver's side cylinder head. If you disconnect it, the PCM falls back to a default pressure, and if that allows the engine to start, that usually implies a failed ICP.

Did you check fuel pressure while cranking?

 

[Smokin_Strokin]

No I the old truck has 350,000 miles on her and its probably a good idea to go ahead and swap it. Ive done got the turbo about off now... the pump I'd say is the stock one by the look of grease on this engine. Thanks for the info on the ipr and icp bud I unplugged the wrong one lol... knowledge is everything
