03 plate 147 intermittent starting (SOLVED)
About a month ago my wife's 147 threw up tons of error messages when she tried to start it.
ABS, EBD and VDC errors flashed on the dashboard. Turns out the battery was low and a overnight charge sorted the issue.
Fast forward two and a bit weeks and when she went to start it cut out when put into reverse. On restart there was a MCS failure warning, so I took her to work. On my return I tried to start the 147 but with no joy. On key insertion to MAR position, sometimes the dash would come on, other times not. Sometimes it the starter motor would turn over (but not start the car), other times not.
Left the car for a few days while I waited for my old man to bring round his charger. Car managed to turn over and start after some fiddling around (mostly with turning it to MAR and seeing if the dash came on, and only then trying to turn over the starter). Managed to start the car, still had MCS failure, took it for a drive around the block. Aside from MCS warning, everything was fine.
Came back, tried to start, started only on the 4/5th attempt.
Thought it must be the battery. Checked voltage (12.4), checked while running (14.5) - decided to charge overnight and get battery checked out anyway.
Charged overnight - first turn over, just starter motor turning, engine not firing. Second attempt, all good. Take to local guy, he checks battery, seems fine, but I decide to replace no name brand battery with one with more oomph (after reading here that Alfas are susceptible to weak batteries). Still not happy either turning on (i.e getting anything on the dash when key in MAR position) and still only starting maybe twice out of five attempts. Sometimes the car turns over, but the dash is dead.
Mechanic has suggested it may be the crank sensor. Car runs fine when driving, hasn't cut out or died on me.
I've also noticed from time to time the ignition switch barrel seems a bit 'fiddly'
