89 260e cranks won't start

[BHOARD]

I drove the car home from Thanksgiving dinner, the car was running great as usual. Today it turns over but won't start. It seems to try a little when the key is released.

I've spend several hours reading other threads.

so far I have checked:
spark--good and strong
fuel--pump runs and even tried to jump it--still no start
fuel filter was changed about 15000 miles ago
Thinking it may be fuel I tried starting fluid -- still no start
cps--818 Ohms cold (cant get it hot)
ovp relay--New 90 days ago (put the old one back in-still no start)
Plugs, wires, cap & rotor only 3000 old

What am i missing? The car only has 122000 miles.

I'm suppost to take my son back to college tomorrow.

What should i look at next?

Thanks in advance Bob
