Hey guys my 1999 td5 110 is not cranking due to a strong draw on the battery approx 13v before turning key to glow plugs etc then drops to 12v when key is turned. The fuel pump doesn't seem to stop making its noise just sounds like its maxing out and just keeps on going is a new pump with a new relay, i tried different relay but no luck. Tried a new charged battery and no crank still, a couple of times at the start it did turn over but not long enough to fire just a quick burst.
Any help is appreciated started fine on bump start, unsure where to look next.
Cheers 👍
