Replaced lines from canister to tank. Did not fix problem still shows evaporative emissions small leak

According to the flow meter on my smoke machine there is zero flow in the line going to the filler neck. There is nothing in the evap pump to restrict flow once it leaves the canister. Is there supposed to be some sort of check valve built into the evap canister?

I found a TSB referring to the sheilding wire interfering with the splice for the 5V ref to the crank sensor. I opened up the harness found the splice and the repair had already been made. I taped it all back up per the TSB's instruction. I still have to shy away from any wiring problems with crank ...

The injectors are loosing the ground signal from the ecm. The power wire from the main relay is always hot.

There are no check engine lights. The 5v reference to the crankshaft sensor is good. I havn't checked it to anything else.
