double check your wiring.
I Assume you took off the timing cover and replaced the chain? This is the only way I know of to "get it back in time"
You might have a loose electrical plug somewhere.
Check the crank sensor--and the wiring to it.
When you turn the key on do you hear the fuel pump running near the rear axle?
Does the check engine light come on?
Oh, and this one is important.While cranking the engine, do you see the oil pressure gauge come up?
