Anybody who has experienced a bad fuel pump, what are the symptoms? Thanks!

 

stumbling and cutting out, crappy throttle tip in
low fuel pressure, hard starting

all issues that might not all show up at the same time, and some can be caused by other problems as well

 

hehe i got all those problems....but they dont occur until im at like 1/4 tanks of gas .....kinda sucks when u get ur fuel pressure tested and its fine..and they tellu ur car is fine.....i know my pump is going bad.....btu i cant get anybody to prove it....o well..have fun with ur problem

 

Here's the thing... If you own an F-body and ou take your car anywhere and someone tells you "It's Fine" ... don't believe them.

It's probably a problem thier unfamiliar with... time 2 trouble shoot...

 

My car has like a weird ignition problem, think it could be the fuel pump? It starts turning over then like sparks up with like a laggy sound. But if I turn it off then turn it back on with like 15 seconds of it. Turns on perfect... Fuel Pump?

 

I'm just trying to learn some symptoms. My car cuts out. I'm not sure if it's fuel or opti. Sometimes it won't do it as bad as others. However, It will not climb past around 4k rpm at all. The engine registers knock and retards itself as much as 10 degrees. I'm sure the motor is fine as I just built it. Had the oil pan off yesterday to fix my pickup tube and it all looked cherry under there... Checked my rocker arms too and those are cherry. anyways. thanks for the help!

 

If you are scaning the car to see knock what are your blms at?

 

check your fuel pressure under load.

What should I look for in the BLM's under load?
