Ditto with HT. If you are observing spark by taking it out, grounding metal and looking at the spark that isn't good enough. Under compression a soaked plug might not jump spark to ground electrode but seek ground thru soaked porcelain. Could get no spark, weak spark or erratic. It was wet so it isn't working properly,

The first thing you should be doing is determining if the issue is spark or fuel before you start going after individual components.
It's becoming quite obvious that you are way over your head with this problem and it should be time to pay the professional that knows how to find this stuff.

True but when you have too take a vehicle back 2 or3 times I do not know if you would call them professionals.Every thing is new on igniton side .I think possible short in wires to injector.Last time put in new injector only problem I had was on 1.When I put back together then problem also developed on 3.
