Default Starting problems

I just recently have had trouble getting my car to start. When I crank it, I can hear it almost fire, but then it won't start up. It will always eventually start, and it will usually pop once or twice, then it runs pretty rough at idle.

All of the ignition system is new beside the coil and ICM. I'm guessing I'm not getting a hot enough spark to fire it up from the coil. The coil, to my knowledge, is original(104k). Would it be possible that I have a grounding problem? I just put the engine back in, and I may have missed a ground.

Thanks for the help.

Check fuel pressure via the schrader valve and check to ensure that you have spark at the cylinder. That should at least point you in the right direction. It could very well be the coil or ICM, but I would check to make sure it is an ignition problem before throwing parts at it. Check and double check all the grounds and hopefully you'll get put on the right path.
