Well last night i parked my truck and went to leave this morning and it wouldnt start.figured the batteries were low put a charger on em..didnt work so from there i took off the quadzilla and back to stock that didnt work..i also opened the valve on the pump..fuel came out..then i checked the injectors to make sure they were getting fuel and they were..still would just crank!!! I wasnt even driving it hard before i parked it got up to 55 mph and only about 4 mile drive...what could be the problem?rail pressure too low?

 

Try putting some SeaFoam in the fuel filter canister. Mine was doing the same thing and would only start with SeaFoam in the fuel filter canister. It ended up being the injectors. hope you're luckier than me!

 

miles? anything ever been replaced? No cel?

 

It has 81k on it..we r thinking maybe fuel filter gonna try this evening after work..I hope its not either of the pumps or injectors

welp..put a new fuel filter in but that wasnt the prob...hooked up obd2 to it and my quadzilla threw the mass air flow sensor code,fuel pressure and map sensor..cleared the codes checked rail pressure on high side and low side everything is fine now..we dont know why it went crazy like that!!

The fuel pressure was right at 6000psi so its about prefect!

 

Awesome man! glad you figured it out.
