    First off it is about 25 degrees outside, got in it tonight, and it would not start right up, it would just crank, after two tries it did turn over, ( i thought it was just cold) well drove about twenty minutes parked for a couple of hours when i left it turned over just fine on first try, stopped at video store and no start, just sits and cranks, it has battery power, and all plug wires are on tight, i will change them out tomorrow, but i dont think that is it. Can anyone give me a headstart on maybe what to be looking for, as i said it will sit and crank for all its worth but will not turn over. Thanks For any help

    I see that you have tbi. Can you hear the fuel pump working when you turn the key on? If you don't hear a high pitched whine, maybe your fuel pump is shot??

    I had the same problem happen to me. Check the electronic control module in the distributor.

    Take a lug wire out and put it up against a bolt or something it will arc to...check and make sure there is a spark...if not, check the ignition module and pick up coil in the distributor, and the coil...the modules like to go out, pick ups go out every now and then. As for the fuel pump, try and hear for it when you turn the ignition on, or look in the TBI for gas spraying in...if its not starting and it smells like gas really bad, it wont be your fuel pump anyway.

    If you suspect the fuel pump get someont to shoot some starting fluid or drip some gas down into the tbi. If it starts up for a few seconds then it's the pump.

    I had a similar situation on a friend of mines truck this weekend. her fuel pump was pumping fuel but just not enought pressure for the tbi. So i would do like everyone else has said check for fuel and spark but dont be fooled by a pump that you can hear. be sure to check the pressure.

    Finally Something I might be able to HELP WITH!!!! Sorry
    Just went through this with my 89 burb after trouble shooting the tbi and all related items, connections and issues. I then checked for spark. No spark Changed coil and only got a few starts. So I started over with the help of this board and the sugestion from "Muddytazz", started looking at ground issues started at the starter went to the coil and then to the Distributer. What I found was that the control modual had come loose or the P.O. had never really tightened it down. I tightened the two screws for it and have had no problems since.
    Hope this helps.

    I would check the distributor module..Most auto parts stores like Napa, Checker, autozone will check the module for free if you pull it out and bring it in.
    On some fuel injection systems if the computer doesn't see a signal from the dist module it shuts off the fuel pump to keep the engine from flooding when there is no spark. If yours is like this you may not see any gas coming out the injectors.
