I just replaced my VP44 and i tapped the wire for the tst before i put the pump in. but now its not working. the Boost light and the On light lights up, but the fuel light is not lighting up. I also have this stacked with an EZ. does it matter if you have the EZ pluged into the map first or can it be either way and not matter. I used scotch locks to tap the wires and maybe it didn't cut threw the insulation and isn't making contact. Also i thought i heard that when you dissconnect the tst you have to unplug everything and then plug it back in to maybe reset the box. not sure if thats right but i really don't know. any help would be greatfull. Thanks
Nate

 

Have had same thing before, when I unplug my TST.
Replace the 5v inline fuse...just downline from the 3 light box. They look good sometimes but still needs replacing if no green fueling light with everything else as it should be!

Plug TST into engine MAP recepticle... EZ into TST... Engine wire harness (MAP Plug) into EZ. AND EZ into Data Port!

Good Luck - RJ

 

Nate,

With the yellow boost light and the red power light both illuminating you have a good connection to the solenoid wire on the VP. Try the fuse like RJ has suggested. If that doesn't work get on the phone with Mark or Scott at TST and they will walk you through everything it could possibly be. They are both very helpful!

 

Ok i see what you guys are both talking about looks like its easy to get to as well. jeezs when i got done putting my pump on yestarday and then that didn't work i about went crazy thanks for the information. oh can you get that fuse at about any parts store?

 

Yup!

RJ

 

Yep, should be able to find one almost anywhere.

 

Nate I had the exact same problem and it turned out to be the ground.
