Toys about to be thrown out of the pram... :mad:

Connected everything up, & starting it gets a clunk from the starter solenoid (I assume) & nowt else - no attempt to turn it over. Any ideas? I'm not sure where to start tbh!

Any input from people who've done the swap on pre-facelift cars is particularly appreciated! I've not done any C101 mods so far; as far as I'm aware it should run without? I've run the wires for the swingometer & rev counter, but not connected them up yet, as I didn't want that to be a cause of any problems!

Erm... haylp?! I'm gonna go connect my prop & exhaust...

I've not touched it, so I'm not sure! Will have to check...

Anything to do with auto gearbox inhibitor stuff? Engine was in an auto e32 before...

Well the pram's still here, but the toys are long gone!

Prop (perfect fit thankfully), exhaust, bonnet are back on so it's as good as finished... it just doesn't work :(

There's definitely some current going somewhere when the starter motor should be turning - the interior lights dim slightly. I've not had a chance to investigate much further, but I guess the starter motor could be stuck?



Somewhat predictable that it wouldn't just go at the first attempt but still... :x

If the starter soleniod is clicking then its not being inhibited by anything. Have you got the heavy duty wire running from the battery terminal straight to the large connection on the back of the soleniod?
Have you got an engine earth strap fitted?
Does the engine turn over by hand?
Is your battery in good nick?

If you say so! Wasn't sure how any such system might work...

Can't honestly remember... I'll check. Is that for the earth or the +'ve?
Have you got an engine earth strap fitted?
Yep
Does the engine turn over by hand?
Not tried since it's been in the bay, but it did before...
Is your battery in good nick?
Well it was, & the headlights were bright etc - I'd have expected some signs of it trying to turn over if the battery was just flat, but a charge won't harm it I guess!
john
Thanks! :)

The + battery clamp should have a couple of wires bolted on to it. One of them, quite a thick cable should run down to the back of the starter solenoid. Check its there.
Also put the car in gear and rock it backward and forward whilst watching your front pulley this will let you know if your engine is seized or not.

Also when you do get it to turn over it may take a while because the fuel lines will all be empty. I bridged the fuel pump relay and ran the pump for a minute before trying to start up. You actually hear the fuel gurgling around the system and the pitch of the pump changing. Just did it to save my battery.

Don't thank me, sponsor me on the link below, you know you want to :D

Will do... there's definitely 2 cables to the +'ve terminal - not checked where they go, but I've not touched any of the wiring to the starter - I assume whatever should be there still is!

Yeah easy enough to check, but I blimmin hope it'll still be ok!

Fully expect that one, but it'd be nice to get to that stage first!

Will do - all I've got at the mo is some cr@ppy ones of it in-situ taken with my phone, so that I could see what the clearance was like from another angle! I'll take some proper ones though... :thumb:

Fingers crossed your m3 prop will bolt straight on. Think I'd have had to shorten it though to go on mine!

Just found this picy on my H/D so thought i'd chip in.

You should have two small terminal's, one's for the 8mm nut and the other 10mm so you can't get them the wrong way around.

Your big main feed should go to the battery and the altinator.

The same thing occured to me, but apparently that's a body-side thing not engine-side?

Nice one - I'll have a look tomorrow... shame the starter motor's not easier to see! Should there be an earth to the body from there too, or just the one from the block?

Good point Jon, mine was an auto and I had to make a bridging wire to go behind the glove box to bypass the wiring to the autobox. But saying that why is his soleniod clicking ? Surely he would be getting no click at all.

Earth is via the body of the motor to the block, as Andy says the other fat wire is off to the alternator.

Ar yes, thats what I thought tbh. As an engine loom is an engine loom is an engine loom. Not really anything to do with a gearbox loom-->Body--->ECU loom

I don't honestly remember connecting anything from the starter motor to the battery - I think the battery connections just went to the fusebox...

Fingers crossed I'll find a nice chunky wire tucked up on top of the starter motor that I hadn't noticed! :lol:

According to someone (Gareth maybe?) the measured length of his M3 prop was very similar to the minimum length my E30/E28 hybrid went down to, and that was just too long... I'm using the furthest back position on .de mounts. It would have been fine with the engine further forward, but then I'd have had issues with the exhaust mani (well more issues!) & radiator...

You might well find it's ok, or you might need to remove the lock nut to let it go down a bit shorter. Good luck! :)

Fairly sure it'll be the main power lead to the starter motor... Once I'd done the prop & 'zorst I didn't feel like investigating last night, but I'll have a look this eve! :)

& yes, that does mean I've got the exhaust on before starting it for the first time... :cry:
...but I will be re-doing the exhaust before long, so that's not going to last! :twisted:

Oh, & I don't know if I mentioned it on this thread, but I'm well impressed with the work on my prop done by reco-prop! It came back all clean & nicely painted, as well as being a perfect fit 8)

the starter signal for the solenoid from the ignition is prob too thin and not givving the sloenoid enough beans to push open try running a thick wire and touch it on the small connection on the bottom which has a 10mm head nut on it, if it starts now ure problem is because the wiring to your starter motor from the key is not thick enough.

getting a mate to hit ure starter solenoid while ure starting it, and it starting will also diagnose poor thickness wiring.

i think its this because u are obviously drawing current due to the light dimming, this is because of the solenoid

No joy.... That wire that should have gone to the battery was indeed disconnected, but it's way too short to reach! Seriously p'd off that I sold my old engine before getting this one running, but I'm sure I'll manage to find one somewhere...

Tried bridging it with an old jump lead but no joy... not 100% on how good the lead is though, or my battery for that matter! It's on charge at the mo, but it doesn't seem all that keen.

If I can get a longer cable, I'll be trying the battery from my other car... :roll:
