    Maybe a fuel pump?

    The first thing I would do is double check the firing order.Firing order is 1-6-5-4-3-2.Cylinders 1-3-5 are on the DRIVERS side front to back and 2-4-6 are on the PASSENGER side front to back. After you have corrected the order I would disconnect the battery to reset the computer and try to start it again. How strong is your battery?

    If I remember right, when I checked my fuel pump in my S10 blazer, I pulled out the fuel line and had someone turn it over and, while you hear it prime, if you don't see the fuel squirt out of the fuel line you pulled it may be your fuel pump.

    When checking for a spark in different cylinder heads, put a piece of metal inside the plug, put it close to the head, or around the motor, try to turn it over, and if you see an arc it's not that cylinder.
