just did a fass 220 titanium install on my truck last night batterys were dead so the truck has been sitting on the charger all night. went out to start the truck cranked for awhile and finally turned over and ran. noticed a fuel leak on the injector return line so i shut it down and now it won't start at all, i thought my pump might have lost prime so i reprimed the pump and still nothing ran the batterys down to nothing crankin so long. any ideas?

 

Check for fuel at injectors and work your way back. Make sure the fuel solenoid is working. Un hook your line to the fass and turn to ignition and make sure it's pumping. Etc. Only so many things can not be working.
