Not Starting

[grog]

Fuel pump, done this before Andre. Original pump is Mitsubishi UC-T30SU5

No different with spare key. Bought a tester that connects to pos and neg on battery, took pump and fuel gauge sender out and connected them on bike, so when I put the probe on the pos terminal on the pump and turn ignition on im getting 12.8v for about 3 seconds but the pump isn't priming, so looks like the pump is toast ? Any suggestions for a replacement please.

Edit; I sprayed a load of cleaner through the pump and got it going, put it back together in tank, fitted tank and it primed 4 or 5 times then stopped priming. I've ordered a cheap one from ebay to see if that works. I take it there is a filter inside the the plastic pump housing, and am wondering if this could cause any issues for the pump if its dirty.

The filter will just clog up I don't believe it would usually let anything through (except water) that would harm the pump.The filter media ,as long as its intact is pretty Good.

Given what you've just tried - I'm wondering if its the fuel regulator clip on the pump that's broken? That stop's 14's starting

The clip is in place and seems ok

If you have power to pump and its not working, youve found the problem. New pump

Yep, new pump arrived, fitted this morning and problem solved. I bought a £20 pump off ebay, hopefully it lasts.
Thank you to everyone who commented and offered help, much appreciated.
