1g N/T help

[clipto]

I have 1g non turbo and it was running fine, but after a basic tune up of sparkplugs and wires and coil pack it will just sit there and crack, but I wont get any spark. I checked the mpi fuse and the only thing I can is the power transistor. Anyone have any ideas what it could be?

Did it start after tune up? How long did it run.

You changed the coil pack? Are you sure it was a good coil that you used? Have you tried your old one again? If it was working fine and you changed something and it stopped working, I would first suspect the thing that you changed, not something else.

did you follow wire layout from coil pak to each sparkplug .. you might have the order crossed.

If it did not run at all after look and see if u knocked a wire off. Or like they say bad coil pack, wrong order of plug wires

Double checked the sparkplug order, checked the old coil pack but also the 2nd coild pack I got was a brand new coil pack. It stopped running after the tune up, it would only crank, but no spark.

Sounds like u knocked a wire loose somewhere. Can u test power to coilpack

My bad it did start after I did the tune up. Edit from last post.

Both coil packs test good btw.
