Hey all,

So a couple weeks ago, I drove my Disco to my family's house. No issues, no codes. Last week, I attempted to turn it on again, and... nothing. Dash lights comes on, radio, AC fans, but not a peep from the engine. I charged the battery out of the vehicle, cleaned the terminals... still nothing. No clicking, no cranking. I'm hoping the heat wave didn't kill the starter, but I'm not sure what else could have happened. Any thoughts?

EDIT: The Ultragauge is showing an intake temperature reading of 242 degrees, which I'm assuming is an error, and there's no code in the ECU when I hooked up the Nanocom. Immobilizer doesn't appear to have been triggered.

 

Try the relay for the starter. Found in the engine bay fuse box.

See attached picture. #2 is for the starter. You can unplug #3 and put it into #2 spot.

 

You can jumper the starter relay to see if it will crank. You can also get under the truck, place a screwdriver between the battery cable on the starter and the blade terminal on the starter solenoid - it should turn over. If not, the starter is bad.

 

Thanks! Sadly, that didn't do it. It's a bit dark out at the moment, but I'll grab a friend tomorrow and see if I'm getting 12v at the relay. I know my Ultraguage is getting 12.45V and the headlights don't dim when you try and start the car, so I think the battery can be ruled out.

 

Thanks, that's a good suggestion. Out of curiosity, which pins on the relay should I be jumping? 87 and 30?

 

Update: I went into the BCU with the Nanocom and turned on Crank Enable and the engine starts, but immediately dies once you stop turning the key.

 

sounds like an anti theft security issue..... try syncing the odometer to BCU? or v.v.?

 

Sigh...

Nope. Once again, my incompetence is on full display. 3 days of frustration and swearing and it didn't start because I left it in D when I turned the car off.

Sorry for wasting your time, folks. I'll go slink back off into the darkness.

 

30 and 87 are the ones to jump. You can do this with a wire with two male ends that fit down into the fuse box's relay connections (see picture). If you have swapped relays this may not be worth doing since the probability of 2 relays going out is slim.

Also, check your battery connections. If one is not tight you can still get power to the interior but the starter will not turn.

There are 2 ways to bypass the fuze box.




1. Screw driver method (Extinct described before)

2. Create a wire with a female connector and unplug the "S" connection wire from the starter and connect your wire with the female connector to the starter. Then hold the wire to the positive connection to the battery. (see picture)

Important thing for both methods is having the key in the II position. This is the same position as when you are driving. You don't need the key turned all the way so this is a one man operation.

 

interesting...in D....usually you cant remove the key when that happens.....
