Motor starts up, and shuts back down

[android_proball]

Hi All,

Here's the problem.: occasionally, but not always, when I start my motor, the RPMs move up for the start-up, and then they come down and the motor shuts off. I tried to look for leaks, I found none. New battery, and the dizzy and cap were just a bit toasty and I sanded down the brown bits.

- could my dizzy need a new cap and rotor? I just replaced them under 2 mothns ago. New wires, and sparks just about a week ago.

This has been a recurring problem for about a year now, but it's only happens soemtimes on any given day. For exapmple, if I turn the motor on for 5 trips.. But the 6 or 7 start up, the motor turns and dies off, even when I apply the gas pedal.

Thanks All.

any check engine lights when the engine dies like that?

[Accord problems]

check the main relay . they crack and every now and then they will act up.

Only CEL is oxygen. But it alwaS comes on. Main relay is fine, too. I check it regularly lol

Mines starting to do that shit too. it might be the main relay, igniter, fuel filter, fuel pump, ecu, or ign switch, or the grounds on the motor. shits weak I hate when I get trolled be my car.

You know, I do have a different ignition on my cb. I own two keys. Bad ground sounds plausible.. Also I notice power fluctuations when temperature is hot outside. When I turn my lights on, or anything for that matter, the RPMs suffer just enough for me to notice.

I`m with Accord problems, my past accords has done that main relay failure, especially when it`s hot outside. easy to fix. little soldering needed, that`s all.

Hope it is that main relay.

i have this exact same problem! every now n then, same with the rpms when i turn on my lights , ac and even when i roll my windows down
its not enough for the car to die out but enough for me to notice

[android_proball]

Haha! That's so honest how many people have the same issue. Dang well my relay is just fine., like I said I check it regularly. I also had my alternator and battery checked. They're ok, too..

[Accord problems]

check for dirty injecters and replace fuel fillter. problem is still there then check the injecter relay. jk lol check for dirty injecters and replace fuel fillter. then check the fuel pump and all relays to it . or what you can do is take and probe the connecter to the fuel pump and see if it gets constant power while some one crankes the motor.

Why does my main relay get so hot? I've noticed it stops the motor from turning on it it's too hot.

its old and needs to be replaced.

[android_proball]

Cool. So replacing it will sure help then? - what if I run into the same problem w the "new" one?

ignition switch. Pull fuel line. Put it in clear bucket so you can see it from drivers seat. Turn on ignition. You'll see fuel going in bucket. When you try to start the car. You should see fuel stop if its the ignition switch. Mine was pitted so it was not providing full voltage to main relay at that point. I temporarily cleaned the contacts. I eventually replaced it.

If your IACV(idle air control valve) and your FITV(fast idle thermo valve) is not cleaned it will cause the motor to bog down and die also.

They will cause a drop in your idle. And it is normal for your idle to drop when loaded with the ac, radio, turn signal, ect...
