Just clairify things, I only replaced one item at a time. hankosolder2 thanks for the cam pulley info ! Would have never thought they would have been different. My old motor has 3 windows on the cam gear and the new motor has 5 windows on the cam gear. That explains it . Changed the gear and now it purrs like a kitten ! Thanks for all the help.

Also is there a way to " reset " the ECU ?

Timing is correct and compression is well with-in spec at 155-157psi . OEM NGK plugs , stock coil pack . The two cylinders that have the spark issue are numbers 3 & 4 or the two rear most next to fire wall . When cranking it over it sound normal other than random firing of the motor.

Live in VT , New plugs & wires, there are no missing hose's on the intake or air box. There are no codes showing up at all, I used a spark tester that goes in-line on the plug wires to find out the spark issue. Not sure about the coil pack other than they both will work my daughters 98 and it ran fine. Yes I did the timing belt and have double checked that four times now. It will some times fire enough to dis-engage the starter then die. Most of the time it will only fire one or two cylinders then nothing no matter how long you crank it over. Have checked the fuel system for pressure and it is good. Does this help you under stand my confusion ?

I got a 2001 outback with a 2.5 that I recently dropped a rod in. So got a used running 2002 2.5 to put in. Now the new motor will not start. I saw it run in the other car. After installing it in my car it will not run. Sputters at best. Swapped out all sensors, throttle body, all wires and electrical parts from my old motor.Still nothing more. Does have erratic spark to cylinders # 3 & 4. Any thoughts ?
