Ford Aerostar won't start!

FORD AEROSTAR

:( Hi,
I have a 1993 ford aerostar with a 3.0 L engine, it has 210,000 miles on the engine.
It has had an internal oil leak for roughly 1 year, the oil come out of the tailpipe at start up but does'nt seem to come out once you drive it. Anyway recently the car became harder and harder to start in the morning and the engine started to lose power, the gas mileage went down dramatically and eventually it would not start. So far these are things that have been changed or tested.
Spark Plugs, Wires, Distributor, Rotor, Catalytic Converter, Fuel Filter, Oxygen Sensor. We are getting a spark from the #1 plug and we did a crude fuel pump test. (We disconnect the fuel line from the front end of the fuel filter and cranked the engine. The fuel shot out forcefully in the container under the car. Could this be engine compression or fuel injectors? Please help, I am a weekend warrior mechanic at best so please explain everything as SIMPLY as possible.

Thanks!

Hello,

I was wondering how do perform a compression test if the engine won't start? From my understanding of the repair manual, you need to warm the car up to normal operating temperature before performing the compression test. Will you get an accurate reading just cranking a cold engine with the tester in the spark plug hole? Let me know, also we tried the starting fluid and nothing happened. We also hooked a scanner up to the computer and it came back with a "no problems found" code.
