    I had to replace my battery. After doing so, It wouldn't start. Starter turned over great, then cut out. After the 7th time, it finally started. Can anyone tell why? Thanks.

    You have a flex fuel? Slow starts seems to be going around in flex fuels. ECU is reading to much alcohol.

    Not sure why it took 7 times to get it to start. Any time I disconnect the battery to do any electrical work, etc., mine always dies on the first start after hooking the battery back up. I think it has something to do with resetting/booting the ECM.

    No Flex Fuel. A buddy that works at a Chevy dealership told me to hold the positive and negative cables together then put them on the battery. That would reset everything. But it started before I talked to him, so I never did that. Thanks.
