Thanks guys: Tune up done 3 months ago(3000mi). plugs, wires, cap/rotor
Filled up yesterday and only drove about 80mi: Tank is at 3/4 full+
Gas filter and fuel pressure regulator also replaced 3 months ago.
I just checked the OVP fuse: OK.
Although I can hear the fuel pump running, it does not mean it actually pump gas. No smell of gas after tring to start for 1/2 hour. (Battery is getting weak).
My guess: ....fuel related.
Any more guess?
