nick9one1 2 Posted October 28, 2008 Ive been trying to start my 1.9 rebuild with no lock so far. It turns over much more easily than the last block (if you've seen my other threads). But I'm not sure I have the plugs in the right order. From reading other threads I understand that you get piston one to TDC and then connect the HT lead to the terminal that the arm is pointing, then work your way round in the firing order i.e. 1342. but my question is pistons 1 & 4 are at TDC at the same time, and so are 2 & 3. With it being a 4 stroke engine doesn't only one piston fire at a time? So how do I tell if the car is supposed to be firing piston 1 or piston 4? Cheers!

Cheers! 1 and 4 will be at TDC at the same time but only one will be firing, the other will be on the exhaust stroke, there is a diagram on here i'll try and find it for you EDIT: Clicky Edited October 28, 2008 by Simsy Share this post Link to post Share on other sites
