The firing orders correct
Maybe, maybe not, who knows, it aint running though so everything's a suspect.
Your car was running but had a fault, now your mechanic has fooked it up and it won't start at all.
Your mechanic sounds like he is way out of his debth and it's only a mk2 Ibiza. WFT would he do with a mk5 Ibiza 1.4 twin charger 180?
Don't pay him, take your car to a proper mechanic or sell it to me for 20 quid and I will fix it and sell it on.
My money is on the dizzy being 180 degrees out.
Maybe 180 degrees out? Need to see if the plugs are wet too, if they're dry then it could be a fuel pressure problem.
