Does fuel pressure regulator have a check valve?
I have a 2000 Intrigue 3.5 with the FPR starting and stalling issues ! Takes 2 or 3 starts then runs down road perfectly. Ive read online that the test for a faulty FPR is to pull the vacumn line and see if it is wet with gas. I suppose a faulty diaphram would show this. Mine is dry the several times Ive checked it. I'm thinking if the regulator has a integral check valve to keep fulel from flowing back to fuel tank. This could be the problem. What do you think. The FPR tests good but sure seems to be faulty. thanks for ideas ! Dan
