1996 Chevy Truck 6 cyl Two Wheel Drive Automatic 170000 miles
I have a '96 Chevy C1500 6cyl 4.3l pickup. On my way home from work last night, the truck stalled after about 3 blocks. Haven't had any issues with it since my last no-start problem. Made it to work without a single hick up. I tried repeatedly to start, and it would crank but no start. Pushed it into a parking lot and called AAA. An hour into my wait for a tow I tried starting it again, and it starts no problem at all! After about 20 seconds, it sputters then dies.
My first thought is a fuel pressure problem, so I turn the key to see if I can hear the fuel pump, and its humming away for a second or so then turns off, just like it should. I then try to start it again, really hard to start and runs really rough for a few seconds, then putters to its death. Seems to only start when I either let it sit a while or let the fuel pump run its course and shut off before cranking. Haven't had a chance to try and pull codes or really look under the hood, just wanted some suggestions where to start.
A little background on the vehicle, in the last 3 years the alternator, water pump, cap and rotor, plugs and wires, and fuel filter have all been changed at least once. Last year I had a no-start problem in which every part in the ignition system and fuel delivery system was tested and was in working order. Compression test done then also, don't remember exact numbers but they were within range of a new engine. Cap, rotor, plugs, wires, and fuel filter were all replaced less than a year ago.
Not sure if this helps, but this happened when it was snowing fairly hard with gusty winds, and the temp was around 10F.
have the same problem?
