i have a 1997 buick lesabre replaced the head gaskets and up it started just fine. Just needed to jump battery. Ran and got code random misfire and random misfire cylinder #6. Replaced ign. coils and replaced battery now wont start. It cranks just fine getting fuel and getting spark. It wants to start but wont, any ideas out there.

thank you.

Well, if it's getting spark, I'd say you probably don't have a bad crank sensor or ignition module. You mention it is getting fuel, but did you actually do a fuel pressure check? You could be getting fuel, but not have enough pressure or volume to start the car. You should have about 45psi at the test port with the key on.

If fuel pressure checks ok, you may want to go over some of your previous work. Maybe a sensor came unplugged, or a wire broke, or there could be an internal problem with the engine (maybe try a compression test). Also, check to make sure you didn't pop any fuses or fusible links when you replaced the battery.
