5.0 woe's

[mudchucker]

Ok guys, i have been trouble shooting this engine for a few months on and off and still can't get any fire to it. It is a 90 5.0 and i just had it rebuilt at a race shop. I now have a larger cam, heads and a new intake. The problem is now when i have everything hooked back up there is absolutley no spark. It ran great before the tear down, but now nothing. In a previous post i thought we had it tracked down to the distributor's hall effect switch being shot. I have since put in an MSD distributor with the new module on it. I tried to fire it and still nothing. could it be my coil? is there any way to test the coil?

thanks

Aaron
