Engine will not start and run?

The car will restart multiple times, but each time it restarts, it quits within 2-3 seconds.

Hi Errington,

Is the idleing speed aprocimately 700 rpm when it is running well?

Does pressing the accelerator cable helps?

I still suggest checking the main relay.

I have a 1990 Honda Accord 4dr and the problem is that sometimes i can't start the engine. It's like it'll not start and then we leave it for a few hours and restart it again then bam it works again perfectly fine. I don't know what to do. I've wasted alot of money fixing this and it seems like the problem is still there and nothing has changed. If you can, can you please help me, because i'm tired of getting stuck at work or school like this. I think that maybe its due to the heat. But I want to know what the problem is with the car so i can fix it? Why does my car keep doing this?

check basics, fuel , and spark(ignition), and also check the mass airflow sensor along with the airfilter and breather, if the breather is saturated, replace it with a new one, change air filter and change pcv valve.

when i let my sit for a period of time and i go to start it it wont start it turns like it wants to start but doesnt but when i spary start fuild in the intake it starts but dies my buddy was sparing it in while i turned the key and when it start spary until it kept running it started fine for two days and then i went to started it and it didnt start i changed the fuel filter but does same thing. Also i would be driving and it would die and i would let it sit for 10 to 15 mintues and then it would start again can you please help me figure out what the problem is thank you for your time

Hi francisco84, Symptoms are consistnt with an intermittently failing PGM-FI main relay. When it fails, the fuel pump would not work.

i just bought an accord, it runs great but only starts when it wants to, i believe it to be a electrical problem because ive been over the car, everything works on the car. I have spark, the timing is right on, the engine turns over everytime i try to crank it but it only starts 3 out of the 5 times i try to start it, when i let it sit for awhile it starts but it seems as if the fuel pump isnt kicking on all the time when i turn the key on. is there a way to Bypass the original wiring for the fuel pump to something like a relay and a toggle switch. i found a connector has a wire pulled out of it inside the fuse box under the hood, but it is not labeled, could this also be the problem

I had the same issue it turned out to be the ignition coil...
You can also check the amount of pressure the fuel pump is putting out.
If you haven’t yet its probably easier to change the fuel filter.
if there is a power problem to the pump it is usually a fuse or a relay.
If a fuse or a relay is out than it will not start at all.

Hope that helps a bit…

"I have owned all Honda accords from 1990,1991,1992,1993 and average mileage has been over 300,000 "

my car had a new radiator put in and the car a month and a half later had no water in it. started over heating i turned it off and now won't start. what could, be the problem and the cause?

Hi sbrownson,

Most probably the head gasket is blown. Get a pressure test done to confirm.

Before replacement of the radiator, the head gasket most probably was damaged and the problem is surfacing now.

checked ignition seems to have spark(maybe not
enough ?)
Is there anything else to check? I do not know if this car has a computer(it's my son's car) If it does, what
should I do to check it ? Or is there anything I can do ?

Please get back to me...when you can at;

Hi needydecatur2, When sparks are available, the next thing you should check is the fuel. When ignition switch is turned on, listen for operations from the fuel pump. If none, you should check the PGM-FI main relay which is known to fail intermittently. Resolder the circuit board if you fins any cold solders.

Had my honda running fine 3 days ago. Cranks over fine, fuel pumps comes on. First time this has happened. Fixed my door with a couple screws through the door frame. Not sure if there are wires in there that i could have punctured. Please help

Hi jbzshot,

Check for sparks at plug wire end. Pull one out and attach a spark plug. Ground to engine and look for sparks while cranking.

Check the area that you did the screws. Check for blown fuses.

I can turn key on, car starts for about two seconds and quits immediatly every time.

Hello !!

Check fuel pressure and see if the spark plugs get spark when cranking the engine and comeback with the results.

good Luck!

I have a 1990 Accord that has approximately 222,000 miles on it. The vehicle will start fine in the mornings or on cold days however now that it is warm to hot the vehicle will not start when it has been setting in the heat. My wife can start the car in the morning go to work and then in the afternoon after sitting in the parking lot and the sun the car will not start. We then can go back after the sun has gone down and the car will start. Have you heard anything like this?

Try cleaning the EGR valve.

Looks like ECT - engine collant temperature sensor.

99.99% sure your pgm-fi is the problem. i've lost count on how many these i've changed. the symptom that gives it away is it won't start after sitting in the sun. the relay is located under the driver's side near the steering column. its "fun" to change. make sure to get it from honda. it's a big relay with two plugs going into it.
