Hi rafe lovato,

Does the Check Engine Lamp comes on brightly for 2 seconds when ignition is turned to ON?

Is power supply present at distributor Black/Yellow wire at ignition switch on and while cranking?

If yes to both questions above, then the distributor is faulty, either the ignition coil or ICM.

Hi sdragracer,

Symptoms indicates fuel supply is the fault. I would suggest checking the PGM-FI main relay, known to cause such symptoms. Remove the relay and resolder the joints and it should be good again.

engine will start if the check engine light goes off when starting the car. If the check engine light stay on the engine will turn over normal but won't start. Wait a few minute and try and it may start right up and run properly. May start up two or three time and them back to check engine staying on and not start. Wait awhile and start up.

Have you tried checking out the code is? With the key on RUNII the light on the ECU should flash a code at you. This will help reveal what the problem is.

If there is no code stored, try testing for fuel and spark when the vehicle doesn't start, then get back to me.

Hi there,

There is a set procedure for testing coils with a multi meter, but if you have a good spark at crank thats a good sign. I would do a scan as well to check for any set fault codes, start here.

Hi maroon7,

When it does not start, you need to test and find out what is missing, fuel or ignition sparks.

Click the " First Things To Check " link at bottom of post to get an idea what to look for.

If ti si fuel that is not present, the most likely cause would be an intermittently failing PGM-FI main relay. Resoldering the circuit board works.

We drove the car into a street that was flooded and the car got wet inside now the car won't start. What could be the problem? Besides it being wet. What could not be functioning right?

Does it crank or not crank?

If it cranks, check for moisture build-up inside the distributor cap.

If it doesn't crank, ensure that all the starter and ground wires are still intact.

My Alternator Caught Fire today while I was at a drive thru. I didn't notice it at first, then I saw smoke coming out from under the hood and the car quit. The alternator was really on fire, but I managed to extinguish it by unhooking both terminals on the battery and flapping at it with my hat. I unhooked the alternator and it wouldn't start, so I knew that replacing it probably wouldn't fix the problem since the battery was fully charged and the car should have started, but I put an new alternator on anyway. There is no visible damage to any components or wiring, not even at the alternator connectors or wires, all body grounds are good. My headlights and all electrical features work. Engine cranks but I am not getting spark. Checked timing belt rotation via the distributor rotor and that checks out fine. Everything visible looks fine. The red light on the ecu is not lit up or blinking with ignition in on position. All of the fuses in the box under the hood including ignition fuse is good. What is wrong here?

Look at the tachometer in the dash while you are cranking the engine. If the needle doesn't jump slightly and it just lays at the stop, replace the igniter(inside of the distributor).

I am interested to know if the reply about the tach also applies to other vehicles, or just that model accord. I actually found out I made a mistake by looking at a wiring diagram on Autozone that there is a second fuse panel that I didn't find before ( I just got the car). I found a blown fuse to the ecu replaced it, and it has run fine. Thanks for your answer and if you could answer my question about why that would make the tach move and whether that goes for other vehicles I would be interested to know for future reference.

Generally for most cars the above are true as the tachometer is activated by signals from the ICM and coil but sometimes if the cranking speed in not fast enough, it might not register.

You need to check for power supply to the distributor and test the coils condition before coming to the above mentioned test.

This car starts, but then immediately shuts down within a 2-3 seconds. As background info, the engine light is on and was reported as being due to the speed control sensor. The car ran ok for many weeks in that condition. Can you make any recommendations as what may be at fault?

Hi Errington,

I suspect the main relay is not working well. After starting and stalling, it is difficult to restart? Wait and you can start again later?
