Re: Fuel pressure
I just bought a 2006 ranger with 150k, it idle rough and it randomly died on me I check the fuel pressure it was 32psi at key on and 62psi at idle.

Re: Fuel pressure
It'll drop after awhile. If I remember correctly it won't be showing ~60 psi at key on. Only when the engine is running
