Fpr Up And Died
#1
I need help, my car is stranded at work. I'm pretty sure my fuel pressure regulator has died. When you turn the key to 'on' you can hear the fuel pump prime, but the FPR won't hold the pressure. It goes up to 40lbs but drops to 0 with in 5 seconds. If you crank the car the pressure will stay steady but when you stop cranking it, it drops to 0 again.
Its an Aeromotive A1000 and it's got to be less then a year old. Has anyone heard of these things dying all of the sudden? Could it be something else like the fuel pump letting the fuel flow back thought it?

not sure, it was about 10pm and pitch black outside so I wouldn't been able to tell anyway. When I go to meet the tow truck guy tomorrow I'll check.
Could it still fail and not have fuel in the vacuum line?

i pulled the manifold off and the checked the impeadance on the injectors and they checked out fine. I then proceeded to hook up a 9volt to each one to make sure that they fired, all did. The results of these tests seem to say that the injectors are working properly.
Is there a good way to test the check valve in the fuel pump to make sure that is working properly?
