Thread: Ugh! Think my Walbro bit the dust, Under 5k miles.

Well drove to work today in the Sentra ( its nice out ).. Stalled on the way in one time but then started back up.

Drives in fine, Get ready to goto lunch and I goto start the car, ( I always let it prime and when I hear it turn off then I start it ).

It primes, it starts then it stalls.. Try again it starts and stalls and at this point it just cranks...

Pop hood check Fuel Pressure gauge, 0psi... Check fuel pump fuse and its fine..

Do these pumps really die this fast? I have less than 5k miles on this pump.. T25 running 10lbs of boost on stock 370's @ 3bar nothing crazy.

check the pump voltage. the fuel pump relay will also cause this.

Will do, Is that under the hood in the main relay boxes or by the pump? Sorry at work so cant do much research until later when im home.

Thanks

check the voltage at the pump cover under the back seat.

If its priming, it seems like you should be getting some pressure at least.

I've used walbros in a few cars with no issues. I haven't heard of any issues either. I've got about 15k on the one in my white car.

check ur fuze box inside ur car,i had the same problem,the 10mm bolt in the middle of the box was loose

Not priming anymore, Did 1 time.. Car stalled once on the way to work and was then fine. When I went to goto lunch nada.

Fuse is good, but will check fuse box bolt + voltages.. Hope its just a relay or something dumb as the pump is new and car has been driving perfect.

fuel filter?

This!

I ran a straight power wire to the fuel pump with a relay & fixed my problems on the dyno after finding out that my pump wasn't getting the necessary voltage.

Everything is brand new, Car was recently built nothing is older than 5k miles or so.





I will check pump voltage when I get a chance, Where is the pump relay?
