Hi Guys,
I've been having trouble with my engine and need to check the fuel pressure. It sounds like the pump is cavitating or going bad.
Its a 1996 MEFI-1 ECM with the Cool Fuel System.
What should the fuel pressure be?
Thanks.

This 1996 I have seems to be an odd duck...

Thanks Dave...
36psi sounds right.
Speeking with Mark at Precision he knew it was more than the low 30s for the VST tank engines but less than the 40+ for the MEFI-3 engines.

Hmmm, I'm only getting 27-30 psi. Think that would cause the engine to run a little hotter?
I'm getting 180-185 with a 160 thermostat and this trouble began when I had a fuel pump fail.
