New motor, no spark.

Hey guys,
I just fitted a 2nd hand SOHC EJ22 to my 92 liberty, 1st thing that threw me off, was the timing. There are arrows and about 15 degrees off are veritical marks on the valve pulleys. The manual indicates to use the vertical marks. so I did. THen I checked the old motor and it is timed to the arrows. this made me Confused. and angry.

ANyway, I blundered on. and put it all in the car. but now I get no spark. So i ripped off the manifold and evertything and just changed everything over to the one from the old motor as a whole. Still no spark. Could this be timing related? My patchy knowledge tells me that the coil would be told to make a spark by the crank angle sensor. If the timing was out by 15 degrees, we would still get a spark, altho the motor would run badly. Is this right?

I mostly just need to know what is the correct way to time these motors before I start throwing money at elecmagicians.

Cheers,
Steve

Make sure the timing belt is on correctly that might fix your15 degrees out to start with. And unfortunately I haven't had as much time as some of these blokes to understand Which sensors the ECU uses but I would assume that if it doesn't get certain signals in a certain sequence it won't fire.

it should still start or try to...did you use the arrow on the crank pully couse if you did your way out..the right timming mark in on the little teeth at the back of that pully.the no spart sounds more like an earth problem.check that you dont have an eaqrth wire off.
