how to diagnose a fuel pump going bad?

[devonkyle77]

i THINK my fuel pump may be going bad, any clue on what symptoms i would be facing?

[wiggerman]

could be running lean ect what makes you think its going out? one way to check is to see how much pressure you have at the rail

[devonkyle77]

sputtering, and more often with less gas than a full tank

ever figure this out? Pulled my sparks yesterday for a compression test and they had white tips. Running Lean I guess. I doubt the fuel filter's ever been changed (I havent since ive owned the car). Just wanted to know if you came to any soloution because i'm having the same issue.

Check fuel pressure.

like g6 said check the fuel pressure, then make sure that your fpr is also working

When my pump was going bad it felt like someone attached an anchor to my bumper, slow throughout the rpm range. Id change the fuel filter regardless, if thats clogged you wont get proper fuel.

replaced fuel filter and fuel pump 2 months ago.still feels sluggish

I Kinda Had The Same Problem, When I Went To Put My Walbro Pump In I Pulled Out The Old Pump And The Strainer Attached To The Pump Was Clogged And Had A Bunch Of Crap In It, So Once It Got Above Like 3,000 Rpm Under Full Throttle It Would Buck Like It Was Pissed. Put The Walbro In With Brand New Strainer And The Problem Was Gone.
