I'll try that tomorrow morning the coil pack is new I'll see what's up with it and go from there it's just eating me up because the other 3 are hitting fine. I do know there's a ground issue also sometimes the starter will just click then in the same turn it will take off like nothing is wrong I put a jumper cables on the ground and hooked other end up to block ground and it's fine so I hooked a ground wire up that's now ok

It has it's third coil on it it's one big coil that sits in middle of motor on valve cover . I'm going out in a bit to check voltage at coil and ground too. It has new wires on it . And it has a good blue spark I've changed the number 1 plug several times and every time I do it fouls out.i can put a plug on the wire and put plug against the valve cover and it shows spark that's why I'm going nuts I've got gas coming in the cyl I've got spark and it fouls out I'm also going to check fuel pressure . Number 1 cyl is the last injector on the rail that's something else I've thought about
