New fuel pump died in 2 days.

bmwci323 · 01-17-2013, 01:51 PM

Could there be any reason for this happening?
Was it just by luck , the pump was defective? Or is there any possibility of a different issue. The fuse and relay was switched around just for the heck of it.

I could also tap the pump to get it to work again.. But now, finnaly, it will not turn on.

Ideas?

That's certainly odd. What happened to the old fuel pump? Try that one? or it failed too? What brand?

Hey, it's rare but I mean it can happen.

Send it back for a new one. Yuck, I bet that'll be a messy, sketchy smelling box

Clean it out with brake clean good!

Is it really a failure of the fuel pump or is the fuel pump relay bad?

flashmeow · 01-17-2013, 05:54 PM

yeah check the relay and the fuse first.

That sucks man, try to replace it and get a refund together.

bmwci323 · 01-18-2013, 11:36 PM

Yeah, I got a new one in aswell..
First start with the new pump was rough.. The car sounded off.
My car was sluggish when accelerating, basically a fuel starvation issue..

When i tested the volts to the pump I was reading 10.5 , wasn't sure if that was correct.

It feels like this pump will die out again aswell.

Any ideas?
Relay? I changed them around and it didn't seem to make a difference. Although, I never figured which one was which.

Fuse, I also changed over.

I just don't get it

Badly clogged fuel filter? Mileage?

Solidjake · 01-19-2013, 05:32 AM

What brand is the pump?

bmwci323 · 01-19-2013, 10:37 AM

Siemens VDO.

I replaced the fuel filter 8000miles ago.
Car has 98000 miles

Well..
Now that I had a clear mind, I ran my car this morning.
As soon as u started it, I knew It was misfiring, plugged in the scanner.. Misfire cylinder 1.

As it turns out, yes of course my pump needed replacement, and it just so happened a misfire occurred un related which led me back to a pump issue , yet again.

I will do some pulling and proding later this afternoon.
