I have a 2000 gu 4.2 that wouodnt start this mornng. Last night i was playing increasing the boost to 15 psi from 12 and was pushin it a bit to test her out. Hopped in this morning and waited for the glow plugs to warm, turned the key and only got a ticking noise everytime i turned the key. Tightened all the terminals on both batteries and still got nothing. Would it be the starter motor going or just batteries or something else?
Cheers
