What are the symptoms of a bad FPR?

 

Depends on how it failed. Sometimes the diaphragm tears, then you get fuel in the vacuum line. Otherwise, you get incorrect fuel pressure in the rail.

 

As said, your going to be getting either to much, or too little fuel pressure, resulting in the car running rich or lean. You need to watch a fuel pressure gauge whilst driving really to be able to diagnose it.

 

not to jack this but.. i might have this problem also. Adjusting the B&M regulator, i see no movement on the gauge, stays at 50psi, can this be a bad relulator or gauge?

 

Use your gauge on someone else's car to check whether the gauge is busted...

Probably a bad installation job, the B&M requires the use of the modified stock regulator, u probably did it wrong and fucked up.

 

I bought it alredy done up, it was a working unit. The gauge is kinda wiggling, the casing around it so im thinking maybe its the gauge.
