First thing to do is check all the lines leading to and from the evap system components (and everywhere in between). That means check lines going to charcoal canister, purge valve and leak detection pump. Pull them off and squeeze the ends to see if there are any splits. If you find any, cut off an inch or so and reconnect.

Already have done that .
I'm gonna put one from junkyard on an see if it changes anything..gonna try LDT part 1st..
Then solonoid.
-----Would really love to do a test on them if I can though..----
It is getting correct voltage also.
When I replaced old charcoal canister there were loose pellets in it but I used compressed air to clear lines..

The pump and solenoid are shared among many Chrysler vehicles. I just swapped my LDP with one from a 2009 PT Cruiser in the junkyard. You can use ebay to look up parts and view all vehicles that they fit. PT Cruiser and dodge ram from a wide range of years, if I recall correctly.
