My 1994 Escort LX overheated but didnt seize. It turns over and im getting air, fuel, and spark. First thing I checked was the timing belt but it is right on so it can be that, but I am all out of ideas. I have oil and colant I dont think my head gasket blew because I dont have and oil in my coolant and my oil isnt geting foamy or frothy. So does anyone have any sugestions?

I would check the quality of your fuel. I had similar problem one time on a 64 Econoline 6cyl. I was working as a Plumber one time and drove to work and it would not start at the end of the day.....I had half a tank of gas, but when I drained some of it into a clear jar, it was muddy looking. New gas was golden clear......so I drained it all out and put in a fresh gallon and Varoom.........it fired right up. Maybe just try spraying some Starter Fluid into the Air Intake first..........

First things first!

It overheated...why?

If it is indeed getting spark, fuel and air...it ain't doing one of them properly.
How did you confirm that these items are working properly?

Sounds like you confirmed the timing belt is lined up AND turning...with your normal compression tests..and the plugs are sparking as you turn it over.

When you crank it, does it spin fast...or kinda choppy like it has good compression just ain't firing ...or does it seem to have moments where it tries to start but just won't catch?

Do you hear your fuel pump run when you turn the key to on?
Fuel pressure at the valve on the fuel rail?
Wet plugs after cranking?

My spider senses are tingling toward fuel delivery, but not enough info for an intelligent response.

I would want to double check for the right fuel pressure, not just some fuel pressure. Could have overheated due to going lean.

Well i think im gonna check the fuel pressure because I assumed it overheated cause it was low on oil, because it was, but it could be a combo of the two.

How's the coolant condition and level? Low coolant would lead to the easiest overheat situation. Yes, a lean running engine can run hot and start to melt-down combustion chamber parts as well. Was fan operating normally prior to issues?

not sure bout obd1 but my 96 blew the head gasket from overheating, wouldnt start after it cooled i had to take the battery loose to clear the computer, i know some ecu's wont run the engine after overheating to keep from any furthur damage, just a thought

Brilliant deduction my friend.......I don't know if that is this OP's problem or not but that idea sure goes on my check-list for future diagnosis. Thanks for sharing that.
