I have a 97 voyager van 3.0 engine it has a very bad idle problem the van just shakes very bad when cranked at first it started running rough and then quit all together installed a new fuel pump it starts now but idle so rough the van just shakes all around can anyone help me please with this issue any response will be helpful thanks everyone one more thing what else will make the fuel pump not come on other than fuel pump relay and fuse

 

Are the spark plugs and wires working right? Are there any vacuum or other rubber hose leaks? Are the Fuel Injectors terribly dirty? Is the air cleaner obstructed? Are there any codes?

 

my fuel pump is new i put it in and the blue wire is getting current but the green and white wire nothing the sending unit works but the pump won't pump the green and white wire is for the pump i think help

 

Does it backfire at all? It may be that the timing belt is bad. Just a thought.
