Did the wait to start light come on? Mine did the same thing, had a bad relay for the for the wait to start system. Switched it with another relay and it started. If you have the owners manual look where the relays are and mark them before switching them, if it starts then you can replace the bad one.

the fuse for the wait to start lamp is #19 in the interior fuse block. it also controls the overdrive cancel switch. but it also has most of the other dash lights on it. i agree with 460+ to check and make sure that your glow plugs are functioning properly. cause i believe it should still start if you wait approx the usual amount of time.

no wait to start light means no power to pcm, like said before there is a blown fuse , the fuel heater is probably causing your problem, unplug the heater and replace fuse , should start

Yep, fuel heater, had the same problem. Unless you live in extreme cold climates, you dont need the heater anyhow.
