I am in the middle of replacing my head gasket panda 2009 petrol.
Question is, on the top of the inlet manifold, there are 4 wires that are connected to four square Yellow connectors, i have caught one and pulled it out, it has a vee shaped tiny metal prong, when i look where it came from, i can see a tiny copper winding, have i buggered it up, or should it go back!

Disconnect them all properly. Then if it leaks or plays up on restart, you'll know its the injector you messed up.

I am pretty certain i have buggered it up, and not sure how to disconnect them! i wonder if i can solder the broken wire back in place?

If the connector is damaged you would be better to cut one from a scrap car with a length of wire. Then you can cut yours and solder joint the wires. If the injector is possibly damaged get one of those at the same time.

Thanks for that Dave, when i get the cambelt back on I will start it up, if it missfires i will poke the broken wire down the hole, if it runs smooth, then i will do as you say and chop one off a scrapper, good idea!

No Worries

Edit - Reading your original question I think you should get a (used) spare injector and connector as it sounds like you might have damaged yours..

Yes i will get a spare injector, thanks.
My head is going round and round at the moment! i have been reading all the guides on replacing the cambelt and timing the engine, i have a mark on the crankshaft pulley, i have a mark on the camshaft pulley (but no corresponding mark at 9 oclock) i have tried starting the engine and its not firing (i have the dimple on the alternator pulley correct) so i presume my crankshaft is 180 out, i am struggling to see the flywheel notch through the little hole even with a mirror, so i will try to line up the notch, then use the cambelt marks to align with the crankshaft pulley mark and the camshaft pulley mark, and put it back together, if it wont start the problem is something else

Use the engine front pulley.

Set piston #1 to TDC. Ideally use a dial gauge on the piston top but you can use a wood dowel and turn the crank back and forth until you find the middle (highest) point. Use a bright paint mark on the front pulley to show if the crank has moved.


Set the cam shaft so that both cam lobes on #1 are pointing up. TDC is mid point between inlet closing and exhaust opening. Use a locking pin to stop the cam turning.
