01 Disco won't start (but turns over)

[alzerom]

Here's a short list to get you started: http://www.obd-codes.com/trouble_codes/landrover/
Sometimes one failure can cause more than one error coded because the parts are inter related or powered off the same relay and the relay is out.
My novice diagnosis is crankshaft position sensor is causing the engine to misfire on multiple cylinders or simply not start.

There's a good blip of information over here on another forum about 1668 and it's involvement with the alarm system.

Re: your fault codes

They are all pointing toward your crank position sensor and, specifically, PO335 = "Crankshaft sensor circuit fault - no signal."

PO327 = "Knock background noise low, bank - A"

PO300 = "Misfire on multiple cylinders (NAS only)

PO308 = "Misfire on cylinder 8" (NAS only)

PO307 = "Misfire on cylinder 7" (NAS only)

PO303 = "Misfire on cylinder 3" (NAS only)

P1668 = ?????

So I just got the scan guage results:

all start with "p" and numbers are 0327, 0300, 0308, 0307, 0303, 0335, 1668
