    I am posting for a friend, he has a '97 S-10 with a 4.3L. He was driving down the road and it acted like it ran out fo gas and died, it will not restart now. We shot some starting fluid in the TB and it will not start, it acts like it has jumped time. He has replaced the timing chain, crank sensor, coil and ignition module. We have fire and fuel, just cranks and back fires through the intake like the timing is off. The only sensor left is in the timing circuit is the cam sensor, but I wanted to know if anyone else had any suggestions before he tears the distributor out to replace it. Any suggestion will help. :confused:


    Thanks,

    i would recheck the chain. or take a look to see if the rocker arms are moving.

    Did your friend install the crank sensor correctly? Sometimes, they need to be "aligned". And also
    verify if the crank pulley looks straight and not damaged.

    Everything is good in that area, this is the same thing it was doing before the chain and sensors. I think for some reason it is getting a bad timing signal, for reasons unknown.
    Thanks for the reply :D

    "usually" the cam sensor is only used to time the injectors. Is this a DIS system or does it have a distributor?

    it is possible the crank sensor is bad or the ign module. Check the wiring to the ign module and crank sensor. If it does have a distributor, pull the cap off and look on the inside for any cracks or large amounts of carbon.

    Grab a timing light and while cranking, see how far off the timing is on the crankpulley.

    worst case is your camshaft busted in half or distributor shaft
