Does anyone know what could cause this problem???

Could it be the crack position sensor or crank angle sensor and is this part of the distributor?

Something is not telling the car to fire or send fuel. Fuel pump was jumped at the relay and is working.

something is not telling these items to start. I did not make any changes, car is 1993 all stock, and I just went to start it one day and it would not start after driving it just 2 hours before.

Does your fuel pump kick on?
Your getting no spark at all to any of the cylinders?

Check the fuses for the ECU. Do an ECU code readout to check for possible fault codes being set. It also could be a bad ECCS relay.

The fuel pump will only kick on if I jump the wires at the fuel pump relay, but not when I turn on the ignition. I have checked the odes and I only get code 55. The car cranks but will not start. The battery has now run down to the point that the amps are too low to give a good crank.

Hello,

Problem has been solved. Turned out to be the ECU. I purchased one from a salvage yard, installed it and the car started immediately. Hope this helps someone else.
