I have a 93 honda accord and if i start it up after it sits for a long time its runs fine for a while and then it shut off i have to wait a few mins and it starts back up I've replaced the spark plugs fuel filter and fuel pump thinking that it would solve the problem what could be causing this problem?

there is problem with relay PGMFI is under left leg.

I had the same problem with my accord years ago and it turned out to be that the ignition module would die whenever it got hot and then start working again when it cooled off. It is located inside the distributor and costs a bit less than a whole new distributor. I changed the entire distributor, to be sure all the ignition components were new and would not fail again for a while.

Sounds like the typical main relay problem on your Accord. It runs fine, but when warm, will not restart for a few minutes after you shut it off. Have the main power relay replaced.

Might be two problems, but one is your igniter in the distributor. The second, the idling problem is either your throttle position sensor, or a vacuum leak. With the engine running , check all hoses for leaks by wiggling them around, while listening for a hissing. Check intake bolts for tightness.

It will do this if the car is to hot when turned off.It will run for a few mins then stop.Just stand by the car when the fan is running after you have switched it off wait for about 2 mins then it should go off.good luck.

Have you checked your alternator?

the fuel is bad, check your fuel lines and put new fuel in. fuel does go bad if you leave it sitting too long, next time run your car for 15-30 min once a week to prevent this

Its probably your fuel pump I recently had the same problem.

this could be a few things when the car WONT start open the air filter chamber and get a helping hand , remove the air filter and spray some startingfluid into the tube going to the engine, have the helping hand turn the key over if the car will run then its a fuel problem, it could be a bad pump clogged system, bad spark plugs, or a slipping timing belt.... Try this first everytime you get in the car before starting it, turn everything off (fans,ac,lights,radio,radar detector,) sit down and turn the key to the run position (NOT THE START) wait 10 seconds and then turn the key if it starts then it could be a bad fuel pump..... YOu should be able to hear a slight Humming noise coming from the gas tank ... do this and let me know the results my e-mail address is [email protected]

Ussually with the Preludes the main relay for the fuel pump needs to be replaced. One that i havent seen posted yet is the 'Coolant tempature switch' near the distributor some times becomes faulty. Cheap at local auto parts dealer.
