Grounding issue? Lights come on instead of fuel pump priming

Technical Area Electrics & ICE

Hello all,

My fuel pump has stopped priming.

This has happened since I removed the Zoom starter button.

Instead of the fuel pump priming, the front lights and dashboard lights come on until the relay under the dash clicks.

It sounds like a grounding issue but I can’t find any ground wires not connected under the dash.

Does anyone have access to the instructions for the Zoom starter button? That would help me work out if I modified any wiring during the installation.

Kind Regards,

Andrew

Thanks very much!

So currently the grounding point under my dash has not got anything fixed there, does anyone have anything grounded there? I can’t find any unconnected grounds so i’m stumped.
