Problem with my 2002 Chevy S-10 2wd.
Engine size = 4.3L Vortec V6
Service engine soon

Battery replaced
GM tech = mw
question = It just quit on me. Its like its out of gas. It will crank
over and you can hear the fuel pump and its getting fuel but it just
will not start. I'm wondering if it could be the cam position sensor or
the ignition coil pack. Lost my job and have a child and mother on oxygen
living with me and I have been stranded now for a week. Any info would
be greatly appreciated. I cannot afford a donation at this time but
put you in my favorites and when I get my unemployment I will be happy to
donate.

Well, with any no start condition, you need to find out what is missing. Are you
missing spark, fuel pressure, injector pulse? With the check engine light on, you
would need to check for stored trouble codes.
If no / low fuel pressure, the fuel pump is a common cause. Just because you hear
the pump run, does not mean the pressure is high enough. This engine needs at
least 55 psi. , or it will not start. Even a few lbs. less, it wont start. Banging on the
center of the fuel tank will sometimes free-up a sticking / weak pump to allow it to
start for a while.
No spark can be a number of things. Coil, module, crank sensor, etc
