truck wont start
 

hi ive been havin some problems with my 01 24v cummins. first off when i got the truck i had swap motors becausenit was blown cause of overheating. i got a replacement motor. ever since ive had it runnin its always threw a code of havin a bad cam sensor. it would choke when it would start and then run alright, felt like it had a dead pedal, but i put an edge comp on it then it ran perfectly fine. after i got the truck back from paint it ran fine gettin it off the trailer and then i parked it in the barn. i went back a couple days later after i had assembled most of it and went to move it out. it started fine but only ran for around 5 seconds then died, it did that a few times and now it wont do nothin. i checked the fuel relay it works fine, lift pump is workin good. gettin plenty of fuel to the pump but when i crank it and have #1 injector line craked no fuel squirts out. i figured it might be the pump so i have a good one loaned to me right now and it still doesnt start. the pump has the right degreed key in it and it has more than quarter tank of fuel. im stumped on what is wrong with it. if anyone could elp me out id really appreciate it. thanks :argh:

You bought a motor because it was overheating? Was it even diagnosed or did you just decide to throw a new one in? If so let's just go ahead and suggest taking it to a knowledgeable tech lol.

Will the pump run in standalone? What's lift pump pressure and volume?
Any codes present now? Was the cam sensor code diagnosed appropriately and a cause found for the out of range?
Any fuel leaks? Fuel quality checked?

i bought the truck with the blown motor, it was caused by overheating. not sure what the pressure from the lift pump is and there is no fuel leaks. fuel is a little more clear than normal, but that wouldnt create the pump to still not push fuel. i drained the fuel filter and filled it with diesel that i know is good and it still wouldnt start.

Pressure, volume and standalone are the next items to check.

how would u check both of those, and what do u mean by standalone ?

Put a gauge on it and make sure you have 5psi(minimum starting pressure) 10 psi minimum running pressure, make sure you have 400mL in ten seconds open flow. View my other post for the instructions on running the pump in standalone. If it runs in standalone you know its truck electronics or ecm. If it dosent start you know its fuel or pump related

Does it just sit and crank? In my opinion best bet is to get a OBD scanner and check your codes. This happened to me and it ended up being the VP44. Also, a quick check would be crack three fuel lines right off the injection pump and see how much fuel is coming out. Another thing is if your going to replace the pump might as well replace the CAM sensor to considering you are having problems and it is right behind the pump.

Here is a list of codes that usually mean trouble and a bad pump:
P0216 (often referred to as the code of death and most common code for VP44 pump failure)
P1688
P1689
P0215
P0251 - P0260

your truck will also not start untill it recongnizes the proper oil pressure so if it never recongnizes proper oil pressure it will not allow it to "fire" also from a personal experience of a cummins motor swap i accidentally smashed the wire for the crank position sensor between the motor and firewall during install so the truck ran for two days and problems were occuring becuase of the bad connection so you may want to follow the wires and make sure the connections are ok, check that oil pressure, if you bump your key every 15 seconds that transfer pump should stay allive if not somethings telling it to shut off...

I have a very hard time believing this. My truck does crank for 5-10 seconds to build oil pressure, then start. It starts with .5 - 1 second of cranking, not near enough time to build oil pressure.

not full oil pressure but proper pressure TO start as in if it doesnt recongnize Any pressure it will not start, Yes this does take place ive been told this by countless cummins techs, my truck only cranks like twice and fires up right away

Lol your right. There is no oil pressure provision in the ecm.

Just to prove my point two weeks ago a truck came in with no oil reference on the gauge. G80 was broken clean in half...the oil pressure sensor wasn't even connected to the ecm and the truck drove in the shop?

thanks for all the help. ive been talking to alot of people and have been sayin it sounds like the lift pump isnt givin the truck enough fuel for the injection pump to properly work. i was wanting to know what kindve aftermarket fuel pump besides an airdog or fass. im on a limited budget cause im gettin this truck ready to sell. i was lookin into the holly black fuel pump. i was wantin to know your guys suggestions, thanks

Just my two cents but if you are about to sell the truck, i wouldnt cut corners to get it running so the next owner has to deal with it. I don't know about the holley black pimp but my buddy just out a raptor on and it was cheaper than fass or airdog.

Before my airdog install my lift pump was shot no fuel at all and my truck would run and start not quite sure if lift pump wouldn't let it run unless you have a bad vp44

No crank, no start 02 24V
 

Can anyone help me? '02 5.9 24V. Brand new starter, 1 month old batteries, load test fine, no corrosion. All fuses under hood and in cab check out, no pinched crankshaft wires. Dash lights come on in "on" position, key is turning as normal with some resistance from "on" to "start" (as it should) and still nothing...
What could the problem be? I'm thinking maybe ignition switch or coil? For the likes of me I can't seem to know why it won't turn over....

With a multimeter check if you're getting power to the starter. If not it could be the starter relay
