Non starting Fuel Selenoid

[Kevritchie]

Hi guys,

Looking for some pointers to the issue I am having with starting in a defender 300TDI.

Getting 12v supply at the fuel Selenoid .Engine turns over but doesn’t start .

if I remove the plunger and spring form the Selenoid it fires up . Need to stall it to shut it off .

If I run a 12v supply direct from the battery nothing happens when I turn the key .

Any suggestion welcome

Your solenoid is life expired. Replace with a new one. One last check you can do just to prove it is dead.... Remove the solenoid with the spring and plunger in place, conect the wire to it with the ignition on. hold it in your hand and touch the body of the solenoid against something metalic on the engine to earth it. you should see and hear the plunger move. If not, throw it way and replace with a new one.

Have you seen my loom thread? I had this experience recently and it was the wiring at the ignition switch. Have a look at what I found. Have you don't anything at the ignition switch wiring?

Just seen your reply . Your bang on I’ve narrowed it down to the ignition switch as well . By passed the ignition switch and she fired up first time .

New ignition switch ordered.

thanks for your response 👍
