I seem to have a problem loosing fire while in start position with the key. If I bump it will hit and run once running it'll never loose it again.

What would cause this?

I seem to have two vehicles with this issue. The other on is a little different as in when I shut the key off it will hit once, but while the key is in the start position I don't have any fire.

Any ideas?

Both stock ignitions.

The coil is hot all the time on both. Both have tach's could this be a problem with the tach.......I wouldn't think so. I did have a tach go bad on my 68 gm car back in the day that wouldn't let the car run........unhooked it and the car ran...........I haven't tried that with either of the trucks that I have.

Thanks.
