MYSTERY???? Help........................
My fuel pressure died off to where it would not pull into boost and was hard starting, after sitting overnight and was running fine the night before! With key on & gauge on the pressure was slow to climb to 45 range then fell to zero. Turn key off wait a min. then re-do and same up to 40s then fall to 0. Since I have a trap door in the trunk I was able to clamp the return line at the tank then repeated key on & off. ( Pump & relay all working thru-out this )
With return clamped pressure shot up to 65 then leveled to 45 and held. Ran this test twice more with clamp on and all good. Removed clamp on return line and re-ran the key on & off twice more and all seems as it should and pressure is holding at 45. MYSTERY ????
Plenty of fuel, E-85 if that matters, billet reg. app 2 yrs old, Red A. pump & tank app 4 yrs old , sending unit & rear hoses 1 yr. old New 80 lb injectors & Wix filter 1 month ago................ Any thoughts or suggestions as this is the second time this has occurred and it has me baffled...................
