So I went out to start my truck the other day, and it cranked over and started but immediatly died. Tried a few other times and nothing, so I had it towed home.... yeah im a do it yourself-er. Then I noticed my gauges also werent working, and only the battery light came on, no service engine soon etc. So I replaced the alternator, thinking maybe the stereo drained it, didnt do the trick. Well I gave up for the night, and got back on it the next day, literally did nothing and for some reason it fired right up and i drove it around to make sure it was ok. Brought it back home turned it off, started it again, with no problems. Well today when I went out to start it, back at square one..... only this time, when the fuel pump whined it made a hideous noise like sucking air from either under the hood or the pump itself.... maybe both.... but if it was just the fuel pump.... the gauges would still be working and I am at my whits end..... anyone have any advice? tips? thanks in advance
