XJ 2025H keeps blowing Instrument/ Relay fuse

Have seen an intermittent short in the fuel solenoid on the injection pump cause this. Blows the same fuse and may start but dies when you release the key.

Thanks for this. Will look into that as well. Went to the dealer and discussed a few scenarios. Bought an ignition relay since he said that once the relay is energized it should stay energized. Replaced it anyway - wasn't too expensive. No change.

Forgot to mention check the wire harness on the engine that goes to the fuel solenoid also. The way the engine vibrates like a paint shaker on this model causes the wires to rub through on anything they touch.

Yeah, I never let the rpm below 1200 when I park it

Back in business! I called the dealer and updated him that the replacement relays didn’t solve the problem. He emailed me the full shop manual with schematics. The wire with the dead short fed 6 different switches/ modules. The first one that I tried went to the brake switch. Unplugged the switch and had continuity to the switch and the short cleared. Figured great! Bad switch. Reconnected the harness and still no short! Switch was clean and no sign of damage. Fired her up and went on my merry way! Go figure. Could never have done it without the schematic.
