2003 duramax has a intermittent no start
hey everyone new on here deperately trying to find some answers. my problem began a month ago when my gf filled the truck up with gas. the fpr cut the fuel off so i dropped the tank an wiped it dry an have put twi fuel filters on it. about every 3 or 4 days i can drive it with no driveability problems. you can get in it the next day an will spin but no start. the fpr solenoid is constantly humming if i unplug it it will run but bad of course.it has done this several times. finally i loaded it up an took to a dealer . i left the fpr unplug so we could move it around. so the dealer plugs it up an it ran like a new one.i have a bullydog programmer on it but it has been on there for a few years. so i brought it home an gonna wait for it to do it again. it was setting a code 87 88 89 90 everytime this thing wont crank, the fpr is humming bad. i have no surge at idle with it either . anybody have any suggestions or no what may be wrong ??????????????

well my girlfriend was coming to the hunting land an stop to get diesel but she put gas in it.i have changed the fuel filter twice an no fuel leaks. i pulled the bullydog off of in it .it kinda a wait til it dont crank again.the guy at the gm place thinks it may be the fuel pressure regulator acting up. when it will not start the fpr is humming .
