hey there, thanks for the question.

what codes do you have? you may have multiple issues going on here from the sound of the MAF issue.

but first lets address the spark issue before you can even get it running long enough to check fuel trims for a MAF issue.

check the connector at the power transistor. If you replaced all those items, I would bet there is a corroded or loose wire at the power transistor causing the problem.
