My 93 accord only runs for ten to twenty minutes before stalling. Why?

I have changed the main relay, ignition coil, coolant temperature sensor, and the thermostat. I recently noticed that my bottom radiator hose isnt getting as much pressure as the top hose or nearly as hot.
My 93 accord only runs for ten to twenty minutes before stalling. Why?
there are two possibilities given what you've already done by way of parts replacement.



the first and most likely suspect is the ignition module. the ignition module switches the primary circuit of the ignition coil. It is a transistor and when they fail they usualy fail because of heat that causes the transistor to go open circuited.



the first thing you need to do is to find out if you're losing spark or fuel when the car stalls. How long does it take to restart the car when it stalls? if the engine has to cool down, chances are its the ignition module. If you can test for spark when it stalls and you don't have any then it is most likely the ignition module.



if you have spark then its fuel. there is the possibility that your fuel cap is clogged and not venting so you're pulling a vacuum in the tank as it drains and this can cause a fuel starvation problem. the easy test for this is to run the car with the fuel cap loose and if it still stalls its not the cap or the tank venting.



the fuel filter on that car is the size of a soda can and it takes a lot to clog it. it is a possibility albeit a slight one.



my guess is you're losing spark and the igntiion module is the cause



hope that helps

the car will shut it self off if the temp gets too high

it protects the motor



befre you throw any more money into it thorw a tester on it you can rent them at most autoparts stores



this probally(it may but i doubt it in this year)wont tell you if you have a bad water pump

you did the easy check with squeezing the hoses

another easy check is to drain the fliud a little bit and (WITH THE CAR COOL)remove the radiatior cap turn the car on and see if you have fluid flowing through the rad if it is standing still you probally have a bad water pump



goodluck
Could be a clogged fuel filter.



Is there a %26quot;rotten egg%26quot; smell? You might have a plugged catalytic converter?



Is the %26quot;Check Engine%26quot; light on ( or a little yellow engine symbol) lit up on your dashboard? It could be something in the engine computer or the emissions system.
