hello all my first post after 2 years of reading

i have a 04.05 2500 with the 325 hp cummins.225000 km diablo tuner a power puck banks monster exhaust and a meth injecton. my story i drove home parked it for a week started it up all normal moved it to cut the grass went back the next day and poof cranking over no start. I noticed the fuel guage was on empty ran to the garage put 30.00 in and still no go. so after a bit of cranking it started fuel guage reads 1\4 in tank and engine light on. i noticed a loss of power taking off so i giver the pedal and it took off thought maybe i would help clear it out if it was really out of fuel. drove it about a mile stopped. tried to start same thing cranked over for a long time started again engine light on. i figure its in some type of limp mode got it home turned off and tried to start same thing. But once it starts and idle i can turn off and turn back on right away it will start fine but the engine light still on. i know it wont start right away because the fuel guage doesnt turn on. but if the guage turns on it will start. check all fuses and blew out the map sensor as the codes i get are p 0643,1751,0108,1750,0107 I also took off all the after market stuff back to orginal program and same thing i think i will start with the map sensor?? any thoughts. not enough info i disconnected the batteries for the night try again tommorrow

 

Before you start throwing parts at it check you fuel pressure.

 

I have been seeing some posts on here with similar issues if the fuel gauge stays on empty with fuel light on it will not start. Got to be a electrical issue..if i roll it over for a long period the fuel guage turns on and will start but engine light abs and ebrake lights stay on.....

 

As Tim stated, verify your LP is working. No fuel pressure = little or no go!!

 

It was the fan clutch causing the greef... thanks
