It is quite common for the main relay to have intermittent failure. When the engine won't start, check the fuel pressure when turning the ignition on (pump will only operate for 2 seconds on) or try cranking the engine.

Transmission problem
1994 Honda Accord 4 cyl Two Wheel Drive Automatic 180m miles

Happens only on occasion, mainly after the car has been driven a short while. Starts up okay when engine cold but after 10 or 20 minutes of driving and you turn off the engine for a few minutes the d4 light blinks and the engine turns over but won't start up. If you wait 5 to 10 minutes, the d4 light stops blinking and it starts up normally. Is there a specific problem here? All the repair shops say to bring the car in and they will do a diagnostic on it. But if the problem is not occuring, can they tell what's wrong?

Hi rhstort,

Seems you are having a problem with the main relay. Repair or replace it and your problem should be over.

I was driving 65 on the freeway and suddenly the engine went dead so I have to maneuver it to the right side of the road. When I restart the engine in about 15 minutes, it was ok. I want want to know what causes the problem.

It will probably get more frequent. Of course it is not easy to diagnose these. What ofter is the best is to check the spark to the plug when it fails to start. That is assuming the vehicle does not start for about 15 minutes. Good chance it is the EFI module up under the dash on the driver side. But it could be another sensor. No check engine light?

Hi Brinden,

When it could not start, you need to check what is missing, fule, ignition etc.

Here is link for you to check out.

https://www.2carpros.com/kpages/first_things.htm

You need to check if the water is causing any damage or contaminations to wire connectors and relays etc.

Do you hear the fuel pump come On when you turn key on? If not check fuel pump fuse and fuel pump relay if so, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light.

Electrical problem
1994 Honda Accord 4 cyl Front Wheel Drive 180000 miles

Hi I have a 1994 honda accord. The car runs great except for the occasional refusal to start. The engine will turn over but no ignition. This is the exception to the rule. When this happens I wait a couple of minutes and it fires up no problem. Is this an easy fix?

Hi davidabb1,

Quite often the problem is caused by an intermittently failing PGM-FI main relay. Resoldering the relay joints would solve the problem.

Engine Mechanical problem
1994 Honda Accord 4 cyl Front Wheel Drive Automatic

I had the head for my 94 accord replaced and the guy who did it put everything back together and then the car would not start.
I had another person check it and he re did the timing and said he narrowed the problem down to the distributor. He's getting power from the distributor but it's still not firing, so he said he thinks it's the distributor cap and now i'm hearing something about an igniter. I've already spent alot of money over the last 3 months trying to get this thing fixed and I don't want to spend more if it's not needed (buying more part)
can you please help

Hi magoo,

If the distributor is getting power but the coil is not providing sparks, it is either a bad coil, ICM (ignitor) or a snapped timing belt.

Test the ignition coil resistance.

When I got in it it would not start. Note; I do not have a fob bought from friend who bought at action. Well once in a while I would try to start and it would not start then a day later it would start, then not again. So I sprayed starting fluid down throttle body and it would start for a second, so I checked fuel pump and installed a new one as well as the relay so it still would not start. However, a week later it would start. I would hear fuel pump. After dropping tank twice thinking I installed bad fuel pump that was not problem, I unlocked drivers door and it would start then lock door with key try again and no start. So my question is, is the alarm messed up keep in mind no fob is that the problem? I am trying to make it a reliable car since low miles, but I cannot trust it to start to get it inspected. What do you suggest can I disarm security? Please help!

I doubt it is the security system. A 1994 Accord likely did not have a fob. I have never seen one for one of those cars, and I have had more than a couple of them. I would think maybe there is no fuel injector pulses going on. First off check it for trouble codes by following the instructions in this guide: https://www.2carpros.com/articles/honda-car-1990-1995-obd1-code-retrieval-procedure-and-definition-table

If there are no codes, then I would suggest borrowing a "know it light" set from the local AutoZone. This is a set of small lights that you can plug into the fuel injectors to see if they are getting power pulses. No power pulses suggests maybe a failed camshaft position sensor or something along those lines.

Do that and let us know what you find.
