Hi Mazda forum!I have as the title states a 626 V6. It overheated on the way home from the guy I bought it of. I drove it until it stopped, I shouldn't have. after this it was impossible to start it if somebody didn't open the throttle valve fully. I changed the radiator and then the head gasket (tough job) I have only done it once before on a simple engine, but I was optimistic. Now when all put back together it wont fire it seems like. The spark plugs looked horrid so i changed them and the rotor lid as well. PLEASE I am desperate for help, I need to get this car working!

Thank you for your time

 

Could be all sorts of reasons.
Did you get the head planed?
Timing belt linned up correctly?
Fuel pressure?
Spark plugs firing?

 

listen to grim reaper. do a compression test. check all connections to the cam and crank sensors, etc.
