2017 1500 5.7 cranks but doesn't start seems to a fuel issue.

This is not a coincidence. Communication errors? That's kinda a big deal. What is losing communication?

Unless I'm confusing you with someone else, Pages back, it was suggested that you pull the PCM and TIPM connectors and do a thorough inspection of the connectors. Did you do that?

Yes I did I took them off looked at them clean them reinstall them. That was the first time I got a plethora of different codes. It took a couple of times but they will cleared out except the P025A and the u0109

Ok. So the other codes only occurred after disconnecting the PCM and TIPM? Did you disconnect them with the battery still connected? Or, with the ignition switched on?

After clearing them, these other codes never came back?

I don't remember I did have the battery disconnected at one point. When I disconnected the PCM The key definitely was not on / or in the run position. I looked at the connections everything looked good I sprayed contact cleaner in there let it dry and connected them. Then I got a whole boatload of codes basically not communicating the majority of them. I cleared them then I got less the next time then I cleared them and I think I only got the two fuel pump codes. Then after it started and I shut it down I got more codes which clear out. Except for the two permanent codes from the fuel pump / module.

So here are the codes when I disconnected the PCM.

Then after clearing the codes I got this

Then the next day when it started and I took more readings from the scanner I got this

So I scheduled a diagnostic mechanic to come to the house tomorrow we'll see how that goes. But in the meantime if anything comes to mind let me know thank you!

I would be curious to know if fuel pump will run on command .
If so I would be shaking wires to see if I could make it stop running.

That's a good call. Sometimes the tools and equipment you'd need to buy and training that's required far exceed what you'll pay a good diagnostician.

Well thank you everybody for all your input! Have good news and I have bad news! The good news is the truck is up and running again! The bad news is I am a effing idiot! Once again thank you all for your input!

Whatever mistake you made, others have made worse.

Keeping it secret doesn't help anyone. Lay it out.... What was it?

You'll save someone else the same headache someday, and at the low, low price of some random Internet guy that none of us know, being embarrassed in front of a bunch of other random Internet guys that he'll never meet.

C'mon, spill it!

This is coming from someone who plugged an alternator field connector into an injector, and vice-versa.

The same someone also recently ruined a perfectly good brake caliper and spent hours with that all because of a fallen heatshield....lol

If we own our mistakes and share them, it helps others.

If he doesn't come back and fess up, then from now on any time anyone posts up a problem asking for help, I'm just gonna reply with my Nelson gif.

ASD relay was unplugged?

 

[Ken226]

ASD relay was unplugged?

If we're guessing, my guess is:

sling blade

it ain't got no gas in it! - A funny part from Sling Blade.

Okay, when I first tried to start the truck and it didn't start. When I first started working on vehicles my mentor told me always start with the easiest first so I used the code readers to see what there was and it was the two permanent codes that came up the P025A and they U0109. Which those codes do not go away until the problem is resolved. So that is where I started trying to figure out why it wasn't starting.
So the diagnostic guy came and I explain to him everything I did what was happening etc. He put his tool on it was a Ancel. So there was a plethora of codes that we were looking through everything, not connecting to the radio not connecting to the window motor not connecting to the transmission not connecting to the steering etc. A lot of numbers outside the parameters in which they should be in. Throwing up all little red flags. So then he said we're going to start it and go live to see what's going on. He goes to start it and notices my floor mat is hitting the gas pedal. He tells me these trucks will not start if you depress the gas pedal and try to start it it doesn't want to flood the engine with fuel.
The night before I took my molded winter floor mats out and wash them and put them back in. I have long legs and I don't know if All other trucks have this but under the steering column there's a button to move the break and gas pedal forward or towards the firewall I have it all the way towards the firewall. So when I installed the molded floor mats I put it under the gas pedal but they have the holes in them to Go on to the hooks that are embedded in the carpet in the truck so when I pulled the mat towards the hook it came out from under the gas pedal which I didn't notice. So now the mat is resting on the edge of the gas pedal depressing it. That's why the truck wouldn't start.
If the truck started that first time and was revving high I would have immediately looked down there but being it didn't start and through codes for the fuel pump and the fuel pump control module I didn't think to look down there.
So that's my story and I'm sticking to it.
Once again thanks to everyone for their input and trying to help I really appreciate the time that you spent trying to get me back on the road.

Happy to hear you got it figured out, hope you stick around.

Sounds like the "toyota" excuse.....

All good, glad in the end U were able to get it figured out.

CAVEAT: Many many moons ago bunch of us "military" types under the hood of a Ford Wagon trying to repair the Power Steering Pump. NE way, people got frustrated, and one of the "guys", and no it was not me, threw a hammer in disgust. Unfortunately the hammer went through the windshield, so now we needed to replace a windshield and STILL fix the power steering. Moral of the story: (CHIT HAPPENS)!!!

 

[EdGs]

Yep, all good, most important thing.

Glad you are up and running.

Sometimes, mistakes are like rights of passage.

Stick around, this site is really good.

Did he say why the permanent codes were there ?
