saxo vtr mk1 fault

[sam_16v]

a mate of mine was changing his temperature sensor and he did it with the ignition on (by mistake) so he disconected sensor changed sensor plugged it back in. he went to start his car but the starter wont crank over
is it possible that he has blown his ignition?

Not sure sam, but check fuses first i would say mate.

That`s a new one on me,more likely that he`s knocked an earth wire.

right double checked all his fuses today all fine not blown the fuel pump is priming and everything works except the starter motor so i changed it for him today with a brand new one and it still wont turn over its baffling me now and im getting fed up of working on it cos i wanna fix mine but he pays well lol so if anyone knows if there's a relay etc for starter?

As Stevo67 says it is probably a earth problem.

That's easy to test thou, with a multimeter measure between earth and the wire to the starter motor solenoid (the thin one) and try to crank engine, you should get around battery voltage when in crank position, but if earth problem you will get in voltmeter like 3 to 7 volts, if not power going to starter motor (broken wire, ignition) then you wont get nothing (0volts)
