PUMA 90 WON'T START
New to the Forum.Thanks Martin.
My def 90 2.4 won't start after replacing AC pressure switch due to AC problem.Plugging in Lynx diagnostic under EMS, it says "control module not available".under Security/10AS/TRANSMITTERS-tried to follow procedures still won't start.Any possible leads/remedy highly appreciated.

Sounds simplistic but disconnect the battery for 30mins.
Then re-connect and check terminals are tight and then see what happens.
The Puma can be funny with it's electronics.
Worth a try.

Did you replace the AC switch and have you disturbed something or did you disconnect the battery when you did it?

Check all your fuses and connections would perhaps be a good starting block? You can do that whilst you follow Steve's suggestion with the battery disconnected. Especially fuses 13, 30, 38, 39 and 41.

Thank you.While in a process of eliminating problems re AC I unplugged/plugged different relays to checked on connectivity or corrosion.The last thing we did was change the AC pressure switch.The engine was cranking but won't continue to run seems the fuel line was cut off.Anyway, will try the advice of Steve and check the fuses and connections.

Hey mate.

You've definitely popped a fuse. I would suggest taking them out individually and checking. I notice because your temp is in the red, typical of a blown fuse.

These pumas don't suffer very much from electrical issues, shouldn't have any at all really, even if abused. I have drowned my puma (not intentionally ) was crossing a river once and the road collapsed , became a crossing where water was just above the line of the windows, water had made its way into the section under the drivers seat where the fuse box is found, simply dried it out with a compressor have never had issues...... They quite robust. Touch wood

Good luck

Check fuses in under dash box and underseat.

Temp guge at the max limit indicates either the engine ecu is not powered or damaged or the CAN wires to the instruments are not connected or damaged.

You didnt probe anthing into the AC switch wires did you ?

Also check the relays under the drivers seat. One of these supplies power to the ECU and if it becomes loose causes symptoms similar to this (temp in red, glow plug etc. not illuminating).
