Hi, I have a problem I hope someone can help with.
Firstly I am no mechanic I am more bodywork but…..I am just finishing my current project which is a MK1 Cortina with a YB. I purchased the engine, loom & ECU in bits and have put it together following reading sites like this.

So I have come to point where I try and get her started and after a couple of issues I have fuel, a spark and an engine that fires but will not start (sounds like the timing is 180 out), After checking the timing belt and refitting the distributer she fired up and ran (but not very smooth).

On inspection I had not connected the phase sensor. When I plugged it in it would not start. So my problem is I have a car that won’t start with the phase sensor connected bit will without. Can anybody offer any advice?
