Things i have checked. fuel pump is working (hear it running)
plugs are decent
when i tested the spark there was no spark across the plug i had out of the cylinder.
what could it be

Check for spark at more than one plug. Make sure the plug is grounded. Spark should be blue, not orange. When were the distributor cap, rotor and spark plug wires replaced last? Always check fuel pressure with a gauge. Just because the pump is running, doesn't necessarilly mean it is building proper pressure, and able to hold it.

I am having similar issue with mine starting. got my truck scanned and shows the coolant temp sensor is bad. but about your fuel pressure you need 60psi to get it started.
