hi people i need some help with my2000 wrx turbo.
i recently fitted a new engine but now i have no spark i have only checked
number 1 plug but there seems to be no spark so car wont fire up.
its not the engine that runs on coil packs per plug but with the ht leads leading from the top of the inlet manifold any help would be much appriciated.the car had a spark before i fitted the new engine but now dont.

Is the new engine from the same year etc?
If not it could be the crankshaft sprocket as the crankshaft sensor pick up points might be spaced differently.

no its from a subaru which runs on coil packs so i removed the heads from my old block fitted them to the new block and fitted the engine straight in

thus me be the case but different years used different crankshaft pulleys meaning the pick up point for the sensor is in the wrong place = no spark

Crankshaft sensor and pick up also need to be swapped over as above

Rang around for new sensor for crank shaft and was told the sensors from 93-2000 are the same as are the pulleys is this correct

Affraid not v1 and v2 cars had a wire tail on the sensor v3on plug strait in to the sensor. I'm unsure on the pulley, I know new age are different from classic. Someone on here will know for definate.

It's the main crankshaft sprocket that the belt runs on that's the problem, exactly what I said in my first post. Swap it over with your original one & hey presto!!
You will have to take the timing belt off to get to it.
