Will crank but won’t turn over. Batteries are good, has 4 new glow plugs, a glow plug relay and a new cps sensor. Just changed fuel filter too. Tried unplugging icp sensor and cps so that it would default but still no start. No blown fuses. Have a tuner on it which I also unplugged to make sure it wasn’t the issue. Fuel pump works because when I drain fuel bowl it pumps fuel back to it. Had it scanned and the codes I get are p0232 and p0603. Do you guys think the pcm is the problem?
