It could be many things, but after you have tried the other suggestions, please check that the EGR valve is not sticking open or getting vacuum when you try to start it. If so, you should temporarily disconnect it and look for an improper vacuum hose routing or bad thermo temp valve. First things to check though is improper fuel pressure or intermittent spark problems. Since starting fluid causes it to start, that would indicate a fuel problem. Factory fuel pressure should be at 33.6 psi. If you have the fuel injected model Festiva, you could have a bad injector. If you have a carburetor, check the fuel level in the bowl through the sight glass on the right side of the engine with a flashlight to see if the fuel pressure is keeping the bowl to the proper level (middle of sight glass).

Check for a bad temperature sensor. If there is any code, read it with a scanner, and it will usually tell you what is going on.

Turns over and wont start at times when it dont start watee 10 min then it will start


Does it do it hot or cold , after driving the truck for awhile or sitting overnight ? Heat can cause resistance problems , electrically speaking . Have you checked to see if there is spark or fuel pressure when it won't start ? If you narrow it down to one or the other it makes it easier for diagnosing .

try checking the coil igniter, if this is faulty and it gets hot it will really make your car die but when its cold it will make your car run again.
