truck wont start. 2nd motor. getting tired of 6.0

Ok here's what happened. This motor has less than 100,000 miles on it. Drove it to the store today. Ran fine the way there. Came out and started it up and it had like a lope idle so I took of easy through the parking lot. Lope got worse and worse and finally shut down. Didn't make it home. Will crank but won't fire. Says cyl2 contr code on it. Any ideas?

Used a diablo pred to read code. Had the economy tune on it. Went back to original backup with no change

possible combustion gasses in the fuel rail from a failed injector. definitely a common cause for runs rough and dies

So we went to haul it home and I tried to start it to show my cousin what it was doin and it fired up perfect. It had been sitting for over an hour and was cold. I threw it in gear to try to make it home and it made it about half a mile and it started to lope again. Once it started to heat up it died again. Any ideas now. I'm leaning to hpo leak somewhere. Thanks.

that's possible too. the contribution code is what leans me towards my original thought. usually a hpop leak will result in a low ICP cranking code, P2291

usually a misfire develops in one bad injector and as it progresses the rest on that bank are starved of fuel

you can try one thing. let it heat up to the point where it dies, pull your fuel pump fuse, pull off the secondary fuel filter cap and filter. have someone crank the engine while you watch the fuel bowl for compression bubbles emerging from the lines

edit -

okay the book says pull the FICM relay. that's probably a better idea

I will try that this afternoon. If I get bubbles what does that mean? And if I don't get bubbles? Thanks

bubbles would indicate compression leaking through an injector(internally) and into the fuel lines

Did the bubble test and didn't have bubbles. Wife cranked for 3 or 4 seconds and didn't have a single bubble. What's my next step? And thanks for the help

I also noticed that with the filter out all the fuel in the cup drained out. I put the relay back in and cycled the key a few times to see if the cup would fill up. It didn't. Its bone dry. Think maybe a fuel pump?
