my 300e has big trouble starting it has not been driven in 2 years and it took a boost yesterday but today it keeps trying and trying and finally after 20 minutes of almost flooding the ingine it turned over and stayed idle...but very low...also the rear driver side window will not go up or down anymore my son lowered the window and that was the end of that. how do know if its the motor or the switch because the window wont let up with the front switch or the switch that is acutally on the window...is it coslty to find out? do you think a tune up or fuel pump with the turn over issue?
