I am having problems with the glow plugs system. Have checked plugs and found #3&5 not working. New relay and still no power to plugs. Had it scanned showing PO 562 & 605. New batteries showing 14.4 vt. Running.
Key off - checked voltage on solenoid - 12 vt. To left big post, constant power. Two smaller posts no power. Large post, no power.
Key on, constant power to left large post. Power to both small posts. No power to plugs. Pulled PCM , checked pins, no problem noted. Replaced about 2 years ago. Truck runs great after start. Average cold morning temp has been in upper 30s. Very hard to start. Block heater is out, can not use.
If I have skipped any info please ask and I will try to answer. I also have had a very good diesel mechanic look at it and pulled the codes for me. He advised me to take it online for answers.
Thanks in advance.
