I have a 1989 Subaru Gl 1.8L 4W/Drive with around 80,000 miles on its second motor. I was driving down the interstate doing 75 mph when my rear-end locked up. I towed the car back home and replaced the rear axle. I proceeded to try to start the vehicle and it wouldn't start. I removed the distributor cap and turned the engine over and it didn't move. I have tore down the front end and replaced the timing belts. I first aligned the #2 belt with the locator on the plastic housing and the crank with the three lines aligned at the locator on the casting. I rotated the engine 360 deg. Until the crank was inline again and put on the #1 belt I checked to see if the distributor was facing the #1 postilion and then tried to crank it up and if fails to start. It cranks smoothly at first but becomes sluggish like it is 180 off. Can you please help me? Lesslie.

Align the crankshaft so the middle of the three marks on the fly wheel or flex-plate are lined up with the pointer at the top back of the bell housing. Point the dot on the drivers side camshaft down to the mark on the inner timing cover. Put the passenger side Camshaft with the dot pointing up at the mark in the inner timing cover and away you should go.
