Thanks, I will now be able to confidently tear my bro's truck apart!

Hi, I have searched but can't seem to find anything definitive that relates. My brother has a 94 and he dropped battery cable and shorted it out under hood. (not sure why truck was running) Anyway of course it is now not charging. He has had alt tested and appears to be OK. He has bypassed the ECU with a regulator no difference. He has supposedly checked the Fusible link and its OK, I have been doing some reading and every once in awhile someone refers to crank sensor, what does this have to do with a non charge situation? He is going to bring truck to me so I thought I would pose for suggestions. I cant validate the alt test at all so I will check diodes to see where the fall into the picture. I of course will look for proper wiring from the regulator and for smoked wires and all the obvious stuff. Not sure about this crank sensor tho, anyone explain that one?

I have 20 lbs at idle but about 10 at throttle. I talked to cummins guy and he said f pressure is not the big deal but volume. I have 2 pumps that will throw a lot of fuel.. I plan to measure volume and compare against spec. ......anyone know the spec?

That is why I am here, trying to determine if there is anything I am missing. I am in Canada so pump is more like $2000.00 so even more important to try and figure out. My next plan is to hook up an aux fuel supply/tank and run nice clean diesel and see if that makes a difference. That will eliminate chance of gas still in tank contaminating fuel, lines and all that.

Well, I can say that the pump (lift) is supplying 20lbs, lots of fuel as far as volume goes. I have removed the turbo again and all is free so I put it back on, I have checked for leaks again and none, Truck (02) has no codes now, just poor acceleration and no power to speak of. I can only assume now must be VP44. The truck worked fine before gas event and only thing that worries is the fact that it has had gas in it for quite a few months or the fact of trying to start while diagnosing. I am thinking without lubrication the gas has damaged something. I don't think injectors as Cummins mechanic said they normally will cause skip, stumble or hard start of which I have none.

OK, I put another lift pump on her, I have 20 lbs at idle, I had the MAP out and that did throw a code, I got P1693, P0237 and P0217 I cleared those codes after re installing the MAP sensor, so with lots of fuel pressure from the lift and no codes, no leaks in the turbo anywhere I thought I may have it.....nope, same, a bit better but that may be from the higher fuel pressure to the Inj. pump. I am really thinking my VP44 is toast. It can't be anything else.

OK, Did find a big leak on one of the pipes on the cold air intake. I thought that was it. Fixed it and put it back together and still the same no power issue. Seems like it will only wants to rev to 2000 rpm. Very frustrated. Back to square one. I can pressurize now and no leaks it seems. Not sure where to go now.

OK, I am in the process to check turbo, I have ordered a fp gauge. I have the air boot off the air cleaner side and made a block off with a Schrader and gauge for it. I am pressurizing at the turbo side but have massive air leak at that point it seems, I cant build any pressure at all, I have removed the small line from wastegate to eliminate the gate. same thing. I am not sure if this is the correct way to do it tho. It seems to me the air would just flow out the exhaust side but I don't really know. Is this correct? I can post a pic I think if needed but it is pretty clear what I am attempting. It sounds like air just rushing out of the turbo somewhere. I had turbo off to free wastegate, is it possible that is still stuck open a bit? Not sure how to tell if closed or open. no codes, no apparent boot leaks anywhere but can't build enough air to find out really. Should the turbo hold pressure? Nothing has changed since parking except wastegate stuck, I freed it or so I thought. Maybe it is not returning to closed because of rust or whatever. Seems odd to seize open tho, as in the engine not running it would be closed. Maybe actuator is keeping it open, I suspect I will have to remove that and unhook the arm to determine. My big question at the moment is am I doing the pressure test right? no rags, although good thinking.

Good day, everyone, I am looking for direction on an issue with my 02 24 v. I lent it (mistake) guy put 80 litres of gas in it. It was only run a couple hundred yards to park and pay and then no start. I had it flat decked home and with no idea of gas did a few checks and figured a vp44 failure. I did not repair but decided to wait till this summer when camping season started back up. Fast forward (a few months), I bought reman vp44 and proceeded to remove old pump. In the process I discovered two things, the gas and the fact that the pump had been changed at some point. I believe by a local dealer that is notorious for changing warranty items without customer knowledge. Anyway while putting the reman on at the dealer the mechanic (so called) crushed the key in the pump shaft. It was off by what I consider a lot but the truck worked perfect before the gas incident. I figured at this point the old pump was probably fine cause it was before the gas so why not now? Gas would not hurt it, it was not run at all. I ordered new key to match offset required by pump and re-installed. Truck fired and idles and revs perfect. No codes no other issues except no power and black smoke. I did discover waste gate stuck from sitting so I freed it up and no change. I do not think the pump is the culprit. Any ideas? Boost leak? Something like that? Any guidance on where to look and check appreciated. I have changed fuel and air filters, I have lots of fuel from lift pump (in tank) Black smoke tells me its getting fuel just not burning it. Thanks in advance. Chris

Anyone ever taken the seat heaters from one seat and put in another? I have access to factory heated seats but they are the wrong color so I thought if the elements are removable just put them in my seats.

No, no switch. I assume the plug is in behind the dash, It would be a matter of adding a switch somewhere to turn it on/off, that is my theory anyway.

Great, I have a set of power/heated ,mirrors and will have them put on. I just didnt want to tear it apart to find out.

Anyone know the answer to my question by chance?

Cool, thanks guys

dash have to come out?
