Hey all my 04. First off I'm in Alberta my girlfriend and truck in Newfoundland. Truck started fine ran two mins then died now it cranks great but won't fire. She says she can't hear fuel pum running when key is first turned on and it's throwing a crank shaft pos. Sens code. So I'm wondering if the two are related. And hope some one here knows. Air heate light come on and goes off oil level fine conditioner in fuel. Buy absolutely no startup not even a stutter
Truck was working fine all along now dead.
Thanks in advance people. Dealer and all garages closed today

 

Ok lift pump
Not coming on. Now is it safe to assume
It's dead or can a sensor or something tell the computer to nit allow fuelto be moved? What fuses or relay should I be checking here. Thanks people

 

Sorry I did not see this sooner.
On an 04, the pump is most likely mounted on the back of the canister. If that is the case, they have a super high failure rate.

Below is a shot of the stock fuel filter canister, on the back where the silver piece is, that is the stock pump location. If it's there, you can bet it's bad.



When the pump dies, that's it. She can check for 12v at the pump, but it's probably toast. If you want a fairly easy fix, you can order an OEM replacement from Geno's, but I would spend a couple of extra bucks on a Raptor 100 for the ease of install, or an Air Dog 150 (or higher) if you're going to pay someone to do it.

What is the actual code it's throwing? What are the numbers?

HTH...

 

Ok my bad my truck is an 04.5 in tank pump. The code is p0336. Thanks for the reply.

 

You know for sure it's in tank? Mine is an 04.5, and it had a canister mounted pump. Just asking...

No ! Replace the ECM.

 

Yes I'm pretty certain it in tank. Not 100% but it sure sounds like it in the tank. When it worked. I'm basically wanting to know arethe two things related. No pump and the code ? What are the symptoms of a bad sensor? Has anyone heard of this. Also had a new ignition switch and PCM put in this rig in the past year. It's starting to annoy me with it's problems lol but I love the truck. Thanks

 

I would not think so, unless they are related because of a different problem, such as bad batteries, bad connections/grounds, bad ECM.


Sucks that you are not at your truck. It makes it a lot harder to trouble shoot.

 

Gone to the honest dealership see what and how much. I'm bent over and ready. Will post problem. Thanks all

 

could this be an issue with the security system???

 

I'm hoping not whiskey. But I know not the history as my missus was driving it not me. I hope it's just a dead pump and not an electrical night mare $$$$$

 

Broken wire popping fuse. Now there's a waste gate code P0243 Any ideas what this will cost

 

I'd just get that reset. An overboost code is nothing more than the ECM seeing more than 42 psi. (I think that's the number.)

 

Apparently wires and terminals cortoded and need a new switch or something. 680 dollars need this truck reliable as I will be driving across Canada. Next month. Never cheap fixes. Especially when I am across the country. And have to take their word
