My 1996 eclipse wont start... why?

there is probably something wrong with the transmission, maybe a spark jump gap with the pistons could be. there was a small recall of this type of car in 1999, but only in Maryland. so take it to a car shop to have the transmission inspected.

have you tried the engine control module

What makes you think that the oil is not flowing? because it wont start ? oil does not prevent a car from starting, well least not til its froze up then it wont turn over at all. the transmission will not prevent a car from starting unless its an auto and in gear. if its a manual it should at least try to lunge when you try to start it in gear, since you say its cranking it shouldn't be stuck in gear it would either lunge or just not crank depending on it being auto or manual. verify if your getting spark to the plugs if not work back from there to the coil etc could also be a simple fuse so check those all out also verify that your getting fuel
