idk what all of them together point to but

1093 is low rail pressure
I think 0102 is a maf code being as 0101 is insufficent flow from maf.

Sumtimes it starts then dies an then it'll start back an run fine.

the only time mine ever start and dies is when I have an old fuel filter. Do these codes all pop up at the same time?

 

[wikdlmm]

Yes

If the truck was setting 2 years could the fpr be messed up

Around here it could have a critter in the fuel lines
Have you logged it to check the actual pressure?

 

[wikdlmm]

Not yet

Im no expert but like you said I think your FRP is either opening too much and blowing the FPRV, or not open enough.... If it idles fine I would say it's not opening like it should.


Try cleaning the MAF, and use dielectric grease on the connecter

You should prolly do away with the air heater anyhow. I think Dino said its the same thread pitch and diameter as an ISB Cummins oil drain plug
