Quick back story... a rodent has died somewhere in the engine compartment. Thinking it was under the electrical box on the passengers side, I pulled the box out, no rodent. Put it back, turned key on, no glow plug indicator, a little warm outside, so it did start, a little rough, but smoothed out. Then the indicator came on. So if I turn the key on, wait 30 sec., I can hear the relay kick on. I did test the wiring to the glow plugs and it looks like there is at least 1 plug that is open. Would that cause the P0383 code, and it was just a coinsedence? Btw, think the rodent is in the crossmember, a few maggots dropped down in that area.. pretty gross and SMELLY! I had to tape off the vent area under the hood to keep the smell from getting inside the car.
