I replaced the ecm and the sencoir that contrals the spark. I also replaced the coils, the spark plugs, and wires. the car starts however it is only running on the first and second cylinders is this a timing chain issue or is thier another spark controling device?

Okay, forgive me if this is overly obvious, but did you make sure you have the plug wires going to the right plugs? This car is a waste-spark system where the coils spark at TDC on the compression and exhaust strokes-- so if you just hook the plug wires up randomly there’s a pretty good chance it’ll start and run.
