bad fuel pump??

[skipztt]

well i think i have one of those shitty walboro 255 pumps in my truck. :tdown:

its been giving me a little bit of issues lately, but now it really is bad.
it will be fine for about the first 15 min i drive the truck, then it acts up. i can just be cruising and it will act like it wants to stall and i lose power. especially if i come to a stop, just like normal. it will stall. so i have to put it in neutral and rev it some so, it dont stall.

i know the fuel filter is good, its pretty new.

no codes come up and there is nothing weird on datamaster


any input?? before i put the stock pump back in it, which i know is good lol

we have been down this road with a ty,just change it out,dont bother with walboro they will just give you the steak!!Its amazing how these larger companies get away with this crap.

Re: bad fuel pump??

why do all that work and put a used stock one back in?

Re: bad fuel pump??

cause right now its sitting in my garage and doesnt cost any money i dont have many major mods to the truck, so i dont think a stock pump would hurt anything.

Justin maybe you already know this; but if your truck has been lowered to sit level and you switch to a stock pump you take the chance of starving the engine at 1/2 tank or less.

I had the same problem with a Walbro in the green Ty. Pulled it and replaced it, problem solved.

The easy way to troubleshoot the problem is to have a fuel pressure gauge on the truck while you are driving. If the pressure drops off, you will know for sure.

yes i know.. i have been wanting to mount a guage outside for a while now. just too busy to do it.

yes its lowered, but i think it was 1" thats it, not slammed.

im guessing its that.. just cause this will be the 2nd walboro in the truck lol

Re: bad fuel pump??

Are you sure you're purchasing genuine Walbros??? I have a Walbro in the 93 that is 12 years old now. That's way beyond the life of the stocker that came out.

There has been a lot of discussion about this in the past. If you paid less than 100.00 for it, it probably isn't genuine. It's more than likely a Chinee Counterfit. They are all over egay.

I agree. I have a 9 year old Walbro. I bought a Racetronix fuel pump harness and was going to buy a walbro from them ( iwas going to do preventative maintenance and just replace it). They talked me out of it, they recommended for me to continue using the old walbro if it still working fine....

Not sure about the one I took out of my Ty, but it said Walbro on it. The replacement I bought came in an Edelbrock box but this pump said Walbro just like the one I took out. I think they had some quality control issues a few years back with a batch of pumps.

I am actually getting ready to buy the wiring harness and pump from Racetronix. Anyone had any problems from the pumps bought from them?
