starting troubles

hi my td5 is playing up, starts normal works fine and then suddenly it wont start it wont even turn over and has to be bump started then works fine for a couple days then it happens again, ive changed my injector harness because there was oil coming through to the ecu so i dont think its that, any ideas? and then also my window wipers keep jamming and i had to nudge them to get them working again now they dont work parallel with each other do you think the mechanism is knackered?

Have you checked the starter motor relay?

Starter motor solenoid contacts, dead common on td5 starters, repair kits available ebay etc.
