89 260e cranks won't start
 

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

I have been having the same problems with my car which i believe is the same motor as yours-2.6 liter 6 cylinders. What I have been advised to do is to disconnect the fuel relay and spray ether into the meter plate-this will eliminate fuel delivery and put it into a purely mechanical mode to keep the matter as simple as possible. One can also disconnect the EHA valve to eliminate all electronics from what I have read. You may want to try to crank the motor and check the voltage of the CPS and the ground which I myself have not done yet. I cannot help you much as I am not an expert. My approach is to think from point of view of spark, fuel, air obviously with timing correct. I have have read about vaccum leaks as well which ties into air.

If It seems everything is correct. Do give the air plate and the bore bottom a good blast of carb cleaner to clean the throttle plate at the bottom .there should not a any oil at the bottom visible at wide open throttle position. pull plugs and re-clean. clean pins and re insert fuel and OVP relay.
once i had a similar situation ,the last one did the trick but that was due to non use for a extended period.
