Well my truck wont start now. I installed a walbro pump(in tank) the other day. Last 4 days its run fine, but today I go outside to go to school and it wont start. Battery, alternator, and starter are fine. When putting key in on position I can hear the pump prime. I Am at a loss here. I may end up pulling the bed off and taking a look at the pump again, but I hope it dosent have to go that far.

Any suggestions or ideas?

Any codes?

 

No codes. Does however say that the monitors for evap, o2 sensors and o2 heaters are inactive, but im guessing thats mostly from the fuel not being burned or something.

I disconnected the line from the fuel rails to my fuel solenoid for the nitrous and there wasent any spraying from pressure, and then I decided to go out on a limb and try starting with the fuel rain open.. Nothing, not even a squirt of fuel came out.

Only idea I have left is maybe the pump isnt getting any fuel somehow? I have about 1/2 a tank though, so this seems very unlikely.

It sounds to me like you've got a pluged or kinked line somewhere. If nothing's visible from the outside see if you have pressure at the fuel filter. If you don't, try beating on the bottom of the fuel tank while the pump is buzzing to. I have seen them lock up and still buzz. Those monitors should become active after startup.

 

I have the returnless system with the intank fuel filter, so I cant check there.

I'll have to look some more tommorow.. Its my mothers birthday and I cant be working on the truck all day.

Found the problem. Fuel line blew in tank.



Im surprised I made it home the other day with it like that lol. I guess I should be happy it dident happen when I was spraying!
