Ok, is the check engine light on?

Gave you tested the fuel pressure yet, and if so, what is it?

When it does run and you rev the engine, does it blow whitish or blackish/blue smoke out the exhaust?

Does the oil smell like fuel or is overfull and thin?

Finally, I need the last 8 of the vin in order to pull the schematics
