    need help in fixing 1998 chevy tahoe with a 5.7 I tuned it up with new plugs and air filter 3 weeks ago and it was running great and while driving today it died while driving 45mph and won't start it turns over good but won't start....I poured gas in the throttle body and it isn;t getting spark. I replaced the cam sensor and crank sensor and ignition control module but still no spark......any ideas?......thanks...Tom

    Could be the distributor pickup coil, if so it will have no spark and the fuel injectors will not fire.

    is it the coil that has the ignition control module mounted on it?

    yep pulled them all checked in the bright sunlight....strange thing is that when it died it had a 1/4 tank of gas and when I tried to restart it everything was normal on the gauges but the fuel gauge was pegged past full...

    Did you measure the voltage at the distro and coil ?
    My redneck is coming out here, pull a plug cap and listen for spark ?
    Do the 1-2-3 thing. Follow the electricity from the source to the plug.

    Re: 1998 5.7l chevy tahoe died while driving?

    i had the same thing happen on a 98 ecsb with 305 pulled out on highway and it just died with no spark replaced coil and module first still nothing then pulled the cap and one of the screws backed out of rotor and destroyed everything under the cap put new rotor button in still nothing well come to find out after tearing the front of the motor down just to find a in time timing chain that when the rotor button came lose it actually spun on the shaft so i had to get a new distributor and re time it that rotor button sets on a plate that is just a press fit nothing else hope this helps

    update.....117.00 dollars later and the dealers said it was a blown ECM relay so it was a cheap compared to ignition fuel pump replacement....Thanks for all the it was a learning experience now I need to know how to quiet the wife who keeps saying you should have taken it to the dealer in the first place.......
