7.3 No start

[F250truck]

I have a 2000 7.3L F250. Bullydog tuner and an AFE intake. Tried to start it today and it wont crank over. I'm new to diesels so what should I look at?

Thanks

Do the dash lights come on when you turn the key on?

if batteries are not dead then start at the starter relay on the passenger side inner fender, get a volt/ohm meter, test small red wire for battery voltage when the key is in the start position, if you do not have vbat then it's upstream from relay( clutch position switch, TR sensor, ignition switch, fuse, wire)
if you do have voltage it's downstream (relay, wires, starter, grounds)

if you do not have a ohm meter go BUY one! anyone that wants to try to work on their own stuff needs to own one, most valuable tool in the tool box

Will it "turn over" as in does the starter spin the motor, and just not light?

Do you get a WTS(Wait to Start) light?

Had it been giving you problems previously, and it has worsened, or was it out of the blue?
