I have a electric Fuel Pressure gauge that doesn't move when driveing.
My car was sitting for 3 months with the battery hooked up the whole time, so I had to jump it when I started it again. Since then the gauge has not worked right.

When I prime the pump it shows 75psi then drops to 40psi. Good.
I start the car and it pegs to 60-65 and does not move.

It worked before my car was in the shop. Any ideas? Thanks.

 

Can you smell fuel or see balck smoke, or does still smell like before you got worked on...?

Check to see if the fuel return line, did not get pinched, ect... in some way.

 

It runs just like it did before. Not great but good enough to drive. I have experienced no changes with the pressure.
I know how the motor runs at over 60psi of fuel and low RPMs, really shitty. So I know its not that....Thanks though.

Anyone eversent a gauge back for repair? Got a price you remember?
Thanks.
