volvo kad44 starter motor cutting out

[phale]

Morning All,,
A little problem has cropped up where as i turn the engines over,the starter motor jumps out just before the engine is about to start,and once its jumps out i get the buzzer noise till let the key spring back,,it does it 2 or 3 times and then it will start.This happens on both engines,,any sudgestions?? I was thinking maybe injectors as they havnt been touched for quite a while,the engines have around 590 hours on them. Thanks in advance

Knackered battery. Or duff terminations at battery.

Have you checked the fuses in the black box, also 2 fuses on side of box.
Motor should start as soon as it's cranked enough heat to burn the atomised fuel. Have you checked edc keypad for faults, d button etc should give. 1 1 code.
You could have a sensor down, strange how it starts after 3 goes maybe air in the fuel line. If the batteries were going down I'd have thought they would have given up after heavy cranking.

Thanks for both the relplys,,as for the batteries the one engine is started off two leisure batts linked up and are virtually new,although I'm aware leisure batts are pretty **** for starting,,then the port engine has it's own dedicated battery,,so this weekend I'm going to join all three of them together to see if it makes a difference,,,,you mention the fuses,I havnt checked those,I thought that seeing as it does start after a couple of attempts it wouldn't be one,unless you think differently,,I will check them,,,I will also check for fault codes,,but the big question is why would it be happening to both engines,,it's hard to imagine them both having the same individual components faulty,,I.e. Fuses or sensors ect,,
