Questions and Answers

Another Honda Accord Lost Its Spark

Q. My 1991 Honda Accord EX has 178,000 miles with little or no problem until now. Driving home the other night it just shut off as though I turned the car off. No sputter no nothing. It cranks and cranks but would not and will not start. Had the car towed home and the next day I replaced the fuel pump because I couldn't hear it making that whirling buzzing noise, so I thought for sure that was the problem.

Well, it wasn't I guess. It still cranks like it wants to start, but will not. I can hear the new fuel pump operating now. Could it be the Main Relay? Please help.

Thanks,
Bill

A. It sure does sound like a bad Main Relay to me. You can read my article; Honda Main Relays for information on testing and replacing it. From what you describe it sounds like you lost spark. A bad fuel pump would cause a sputtering type of stall.

There are three, main, items that will keep the engine from getting a spark. A bad ignition coil, a bad igniter and a bad distributor.

To check the ignition coil, measure the resistance between the +, black/yellow wire, terminal and the -, white/blue wire, terminal of the coil. The resistance should be about 0.6 to 0.8 ohms at 70° F. Then check the resistance between the +, black/yellow wire, terminal and the coil wire terminal. It should be about 12,000 to 19,200 ohms at 70° F.

As for the igniter, if the tachometer is working, then the igniter is okay. Here is the procedure for checking the igniter.

  1. Remove the distributor cap, the rotor and the leak cover.
  2. Disconnect the black/yellow, white/blue, yellow/green and blue wires from the igniter unit.
  3. Turn the ignition switch ON and check for battery voltage between the black/yellow wire and body ground. If there is no battery voltage, check the black/yellow wire between the ignition switch and the igniter unit. If there is battery voltage proceed to step 4.
  4. Turn the ignition switch ON and check for battery voltage between the white/blue wire and body ground. If there is no battery voltage check the ignition coil for proper operation or for an open circuit on the white/blue wire between the ignition coil and the igniter unit. If there is battery voltage proceed to step 5.
  5. Check the yellow/green wire between the PGM-FI ECU and the igniter unit.
  6. Check the blue wire between the tachometer and the igniter unit.
  7. If all tests are normal, replace the igniter unit.

If the coil and igniter check out as good, then replace the distributor. Check for codes in the PCM. That will help pinpoint the problem for you.

There was a recall on the distributor also. Read Honda Accord Lost All It's Spark for more information.
