Pulling my hair out! This van had a bunch of codes, I have got rid of of them except p0300 keeps coming back every couple days 50- 150 miles. I have replaced egr valve, plugs wires both 02 sensors, coil pack, intake pelum, and 1 injector #6 because p0306 kept coming back. I also have notice that alot of times the van is also hard starting.(Cranks a long time before it fires up could this be the crank sensor?) As you can see I have throw a lot of cabbage into this van. I.M starting to wonder if the PCM is going south. This van dose have a lot of miles on it for being just 2 yrs old. Hope you People can me out. I'll make it worth your while if you can.I, m a transmmision tech by trade going on 35yrs should stay out engine performance. Thanks David. I, m A man of my word.

I think you need to test your fuel pressure, if it's low, all these symtoms are possible. Hook up a test gauge and see if the pressure is 58 psi + or- 5 psi.
In your case it called the fuel pump module. Even poor fuel can do this!

I havent worked on an 05 yet, but there must be a schreader valve somewhere between the fuel rail, and the tank, if not on the rail, pressure should be 58 psi = or - 5.
