Ph1 172 wont start - Intermittent Problem

[Daz_RT_04]

So the other day I popped to tesco to do some shopping, on return to the car it wouldn't start.

I put the key in and everything lights up as usual, the immob light goes out, turn key - nothing? No noises bar the fuel pump priming and no attempt from the starter (As if the electrics are dead).

5 Minutes later, turn the key and it started.


Weird but I left it at that.

A week later and it's done it again. This time it wouldnt start after 30mins.
Gave it a bump start and it was fine, turned it on and off a fair few times and it was fine? Its started ever since.

Its had a new battery recently so I've ruled that out.

Im thinking starter motor wiring? Has anybody had this?

Any advice would be much appreciated.

Cheers

Sticking starter solenoid or bad connections/earth to it?

Change all the relays under the bonnet. Immob, fuel pump and something else IIRC. Three of them.

Its not even attempting to start mate, Its as if there isnt a starter motor at all...dead as a dodo lol!

Im feeling ignition signal to the starter / starter wiring atm...

also feeling this..

Is on its way lol!

Definitely sounds like a bad earth or relay.

is it making a click when you turn the key? and nothing else?? if so its the starter sticking, thats kind of what it sounds like to me tbh!

i know you have said you ruled out the battery, but i had the same problem 2 weeks ago, it was intermittent for about a month as you have stated with regards sometimes starting and sometimes not; Then eventually the battery gave up all together last weekend....new battery and problem solved for me.

Same as my crappy 1.2 - starter is sticking... I just punched it last time. The starter motor that is (Not hard) and it started lol. Get a new one there not that much.. Not to sure on prices for a 172.

 

[Daz_RT_04]

I havent got any clicking from a turn of the key.

The only way I can get it started is to bump it.



Might try and use a set of jump leads on it next time, perhaps that will tell me about the state of the new-ish battery.

It will most likely be the connection on the starter or a sticky starter its self.

I had this problem and by-passed the relay in the engine bay. I was not getting 12v supply to the relay so traced the wire back to the bulkhead and thats as far as I got. Before anyone says battery ok, starter motor ok and feeds to it, and all earths ok. I assume it is the UCH or relay on this.
