well my 92 x in the morn i'll go out and crank it up, sometimes it starts sometimes its doesn't. When it doesn't i would say half the time i get a pop like "poof" from what seems to be the passenger side of the engine. on my second attempt the engine will start right up. i have read that i should hear a noise when the key turns to RUN, like a whine from the fuel pump, That sound is present, and annyoning i might as too . i have a fuel filter that is only about a year old newer spark plugs and wires Optima battery 130 amp alternator all these parts are new, i fear the problem lies , in the expensive fuel system parts....are my fears true? thanks much!
