Hello,

I have been having a intermittent issue that my 1992 Honda Civic DX will not start.

It currently has no spark and the fuel pump does not ignite and I do not hear more than 1 click from the main relay. I purchased a new main relay from a local autozone which did not solve the issue. Previously, my old relay did work for several days after another no start, no spark issue. The last time that it work, I had to let the car rest for several hours and flick the relay to active the fuel pump and then after the fuel pump prims it was able to start and drive it home.

Several days ago, I had the same issue.
I have checked and performed an oil change.
I have changed the cap and rotor.
I have changed ignition coil.
I have changed the ignition control module in the distributor.
These caused it to work for several days after it had broken down after months of working correctly.

If there any suggestions that you may provide, before I take it to a mechanic?

I am thinking of possibilities with ECU, map sensor or wires, but if you have another other tips or possible solutions please let me know.

I have also check all the fuses and they are all fine.
I reset the ECU by removing the back up fuse for several minutes.
I removed the main relay and jumped the cables for the fuel pump and it primes after doing so.
I have tried adding starter fluid to cause it to start which it did not.
I have disconnected the negative and positive battery cables and allowed them to sit for several times.

Thank you and please.

Did your CEL turn on when u try to star the car? if not
Try to check with tester if there are 12volts in the two Yellow/black wires in your ECU
Check the ground wires that are located behind the thermostat in your engine.

Double check hood fuse 31 and dash fuse 24.
