PLEASE DONT ANSWER MY QUESTION WITH JUST A RECOMMENDATION,PLEASE LEAVE IT OPEN FOR SOMEONE WHO MIGHT BE ABLE TO.

I have codes p0453,p0340,and p1870,the fuel pump pressure is 60 psi with the motor running or just the key turned on and it doesnt bleed off.It is also hard to refuel,the gas pump at the service station keeps shutting off.
Ive been working on this van for two years solving all the problems with it,this seems to be the last thing,and it is cutting into my paycheck. PLEASE HELP
