Crank no start. The check engine light went off after a 2k mile trip. I had it checked and it read the CPS or the # 2 glowplug. I parked it and two days later went to start to move it into my shop and it wont start just a click. Luckily I had a starter handy and fixed that. Then I changed the Crank Position Sensor and no joy. I also found out the glow plug relay wasnt working with no power going through the ignition side but 12v at the other 3 so I changed it out and still no power with the ignition switch on the second post with power to the others. I tried to jump the terminals on the GPR but no start. I am running out of ideas. What else should I be looking for. What is the likelyhood of the new GPR being bad?
