I've got a 2000 XJ that's throwing p0320 and won't start. I've changed the CPS and cam position sensor. I've tapped into both sensor signal wires with a frequency meter and see that each sensor is at least generating pulses when cranking. I've got a little spurt of fuel when pressing the schraeder on the fuel rail. One interesting point is that the ground pin on each sensor connector is about 40 ohms to the neg terminal on the battery. Ground connections look good... is this resistance too high?

What else can I check?

Can I swap PCM's with my wifes 99 XJ?

Thanks
