I have a 1998 Honda civic ex. Once car gets warmed up and I go to shut it off it will not fire back up I have to wait 5 to 10 minutes and it will fire up. If I have been driving and take a exit ramp one of the ramps where you have to drop down to 25 mph because of the turn the car will just die tach drops down to zero even with the car moving. I have to wait 5 to 20 minutes before the car will let me fire it up. Oil battery and check engine lights comes on. No spark at the wires no spark at the coil or ignite. I have replaced the whole distributor with oem. I have replaced the coolant temp sensor and fan coolant sensor. I am stumped don't know where to check next.

 

main relay?

why would you replace the ECTS and fan switch? Neither has anything to do with getting spark to the engine.

 

I replaced them because at the time I didn't know it was giving spark so thought maybe it was over heating.
