scan tool

[craig long]

i was running down the highway and just came off of passing gear and started loosing power and pulled over. it idled very rough and after i pulled off the highway onto the outer road it died. when i try to restart it it fires very roughly but will not run. fuel bowl is filling, turbo wheel is turning. i have taken out the bb mod and taken off the 10k mod. i returned the pcm back to stock and pulled the chip. any ideas?
the cam sensor recall has also been done.
does anyone in the kc area have a scan turn, not just a code reader i could use.....or allow me to test my engine with their icp sensor to narrow down the possibilities?

thank you!

could be your hpop.

another member told me with what i was running that i could not hurt it??

[craig long]

how do you test the hpop?

[dieseldan2005]

oh ok, i guess i was just thinking maybe it was starting to just go out. Cause it looks like you have a few miles on her. It just sounds like an oil delivery problem. That just makes the most sense to me why your truck is running rough. You said the fuel bowl was filling, so your fuel pump should be ok then. Unless its not filling fast enough?

craig i'm not 100% sure how to test it, hopefully a tech will chime in to answer that one bud!

sounds to me like a fuel pressure issue. Just cause the bowl will fill doesnt mean there is enough pressure to run the motor....i would really want to know what your actual fuel pressure is...

there is also the chance of an under valve cover harness disconnecting itself...

happened immediately after getting on it on the highway.

anytime a truck stalls or runs rough....you....

pull codes...
run a buzz test and cyl. contribution if you are able...
test fuel pressure....

fuel pressure is CRITICAL.....buzz test will give you an idea of the injectors and harnesses....as will a contribution...

not to hijack, but marc have you ever used auto enginuity software for these trucks? I was looking at it and it said you can run your own cylinder cont tests and buzz tests. It would be nice to have for situations such as craig's.
