ANSWER: Hi Steven,
There are many possible causes depending upon which engine you have and where the car was originally sold. So tell me about those two factors.
Temperature-dependent no starts can involve either the ignition system being flakey as a sensor is breaking down due to heat or it can be a mixture problem related to among other things the exhaust gas recirculation valve being gummed up. But I need to know the details about the specific engine that you have and its history of first-sale region.
Thanks for the rating and nomination.

QUESTION: it is 2.2 engine with a trottle body fuel system ( replaced with a used one) sold in columbus Ohio I am 2nd owner

Hi Steven,
I would first check for spark when you have the no start situation by pulling the spark coil wire from the cap of the distributor and holding it 1/4" from the cylinder head and then have a helper crank-over the engine while you observe for spark or not to jump the gap.
Then on the egr valve, which is mounted sideways along the pipe that connects the intake and exhaust manifolds and has a round vacuum operated top piece and a flange between that and the body of the valve, find the valve stem which is hidden by the flange and notice that it has a slot into which the tip of a screwdriver can be used to move the stem back and forth. Try moving the stem to see if it closes freely to a dead stop by the aid of internal spring-action. If it is gummed up spray some WD-40 on the stem where it enters the body of the valve and exercise it to free-up the action.
There are or course many other possibilities which might be revealed by a fault code readout, and to do that turn the ignition key "on-off-on-off-on and leave on" doing that in 5 seconds or less elapsed time. Then watch the "power loss" light, which remains "on", to see it begin to flash, pause, flash, etc. Count the number of flashes before each pause, then repeat the process to assure an accurate count of the flashes. Then let me know the flash counts in the order of appearance.
