After the above repairs were compleeted the car would run fine for a few days and then the problem comes back . this is maddening as well as expensive .only sensor not replaced is air intake sensor .engine in the AM spins over but won't start at first ,by fluttering air butterfly it will fire once then twice then start to begin totry to start,thenwill start . motor has good spark at all times .
I know you said you changed all the sensors. Have you looked into the crankshaft position sensor. It can be intermediate when it is starting to fail.

Testimonial: "That is the only sensor that I have not replaced as the comp never showed codes for it . Will look into it , thanks . I am begining to think the ECM is screwy"
Try cleaning the Mass airflow sensor in your intake hose with some rubbing alcohol, that might help with the hesitation as the air mixture sounds like the issue, also try spraying water on your ignition wires with a spray bottle, if you see any arching the ignition wires need to be replaced. How long ago since your spark plugs have been replaced ?
Testimonial: "Thanks for your help I had already done these things you sugested , I replaced the mass air flow sensor The computer codes said it and the air temp sensor was bad SOOO I replaced them . Did not help at all ."

change the transmission fluid, replace the oil and oil filter check spark plug cables, check starter coilpak, and make sure there is coolant

it sounds like 1 of two things either your starter relay is gone and you need a new one ,they arnt that expensive or its your hold in winding in the starter motor this is a bit more expensive but can be changed quite easily.

It could be a faulty Engine Coolant Temperature sensor. It sounds like when it is cold, your computer is interpreting your signal from the ECT (or lack therof) as being at a certain temperature and not providing the right amount of fuel in order to start the engine when it is cold. Does the check engine light blink or flash at all?

When you replaced it with a used one , it was a gamble and one you lost ,time to buy a new one ENJOY
SOURCE: mazda protege 96 very hard to start when cold,
check the mas air flow sensor(is this the 6 cyl) the sensor has a problem with the nose piece inside not moving enough to tell the ecm the propper air flow for the cold start,also check throttle valve for dirt build up around it-if its a four cyl repost
