Alright so had fass sitting around for like a month now the 150/150 and the vulcan draw straw. Well the truck hadn't been dropping fuel pressure it did it again so i decide screw it im puttin it on. Started tues at 5 pm,was hoping to get done that night. Only thing i got done was the draw straw in. Finished putting the fass and tank back in and all that tonite. Go to prime the system and pump doesn't run,check the inline fuse and its fine. So i plug the factory lift pump in to see if it would do anything,and it wouldn't run either seems im not getting power someone please help this is my only mode of transport right now and need to get it running.







BTW its a 99 dodge 2500 ext cab short bed automatic

Did you check fuses? Possible bad fuel pump relay? I'd check fuses... . then switch the fuel pump relay out. You can take a "not so important" relay like fog lights & switch it for a test. Are you powering your Fass off of the stock lp red wire?

Powering the fass off the harness i got with it one end plugs into the factory harness you disconnect from the factory lift pump. And the other two wires one red one green run to the battery

Time to do some testing with a test light if you have one.



Remember, you need to bump the engine to get about a 20 second run time on the pump. If you start the engine, this may over-ride this function and you will need to let the truck sit for a while for it to turn back on. I don’t know why the ECM does this but my guess its something to do with engine stall/accident fuel cut off for safety... .



You can also jump power the Red wire on our harness where it hooks up to the stock engine harness to turn on the relay and run the FASS to check that operation.
