Okay,

I have 98 Civic Dx Hatch. Equipped with a 95 Gsr. Car has been running perfectly fine. I drove it all day today.

-Motor is obd1.
-car is obd2.
-harness obd2.
-jumper harness - p28 ecu.

I started my car to go back out today. Turned around to grab my phone, when i looked back at my car it turned off like someone turned the key off. Like a fuse blew almost. The car now has no spark. I Called my friend, who came over.. We put his dizzy on my car. his ecu. his main relay. I've tried everything I can think of.. The car has no spark but does have fuel pump working and everything else is normal.

I did wash the car about an hour or two before this but it drove home fine. So i don't think there is water in anything or something like that. This is my way to get to work etc.. I need to figure this out. Please help.

 

bump. dying for some feedback

 

make absolute certain that there's no water on your sparks plugs... since you swapped dizzy's you ruled out a wet cap... even the slightest condensation can cause weak or no spark... if you washed the engine make sure there's no water in your distributor connector...

Does the fuel pump prime?

Did the timing belt snap?

Any CEL codes?

 

no cel, no timing problem, fuel pump is working and getting fuel to cylinders. I have no spark. I have now replaced the (motor harness, dizzy, ignition, main relay, checked all fuses, ecu..)

I am now completely lost on what to do. It makes no since. I did not wash the engine bay just the Car. Most i have ever used in the bay is a quick detail spray but not on plugs or wires, just on the bay bcuz' its open and tucked.

 

You may hear the pump working but it may be weak, I've had that happen before when I thought that the pump was working but in fact the pressure wasnt quite enough!
Just a thought
