Does the auto shutdown relay and will that cause this issue

Hello,

What happened when your vehicle's oil sending unit failed? I hate to be the bearer of bad news, but the ASD relay will cause this no start, but only because it is not getting a signal from the Crankshaft Position Sensor (CKP). The CKP sends a signal when it detects crankshaft rotation. The Power-train Control Module uses this information, through the ASD relay, to determine engine rpm's and uses the signal for misfire monitor as well. The CKP is not sending a signal probably because your engine is seized up from lack of lubrication. I have included for you in the diagrams below a description of the ASD relay and how it works. Sorry to be the bearer of bad news.

Thanks,
Alex
