Accord stops running after 5 seconds
 

Hello all, I have a 96 honda accord 2.2l non v-tech that stopped running this past weekend. The car will start if I give it some gas but will only stay running for a few seconds. I have checked the fuel pump and am getting gas. I have checked the TCM , coil ,ICM, injectors and main relay. I am not sure where to look next. This is my commuter car and has 242,000 miles on it. I am stuck driving my truck to work and the gas is killing me. Any help will be very much appreciated.

Is Check Engine Light (CEL) on? If so get the codes. See DIY forum for instructions to extract obd1 codes.

good luck

Sorry I left that info out. About a week ago I had the code catalyst. I unbolted the exhaust before the first cat and it still did not run. No other codes came up.

Can you tell us how you checked each of these? I just want to make sure you didn't overlook something.

Also, when you say it will run when you give it gas, do you mean that you are hitting the gas pedal when trying to start?

Do you have a timing light?

The coil,icm and main relay were checked out by a local parts house. I did an ohms test on the tcm and it checked out ok per the specs that the parts house gave me. The injectors are clicking wich leads me to believe that they are working properly. I could be wrong. If I turn the key over it will just crank until the gas pedal is pressed then it will start some of the time but just for a few seconds. I do have a timing light. This is my first car newer than 87 so I am lost with all of the sensors and such. Thanks for your help.

Sorry not tcm it was the throttle positioning sensor

Lets start with the simple stuff:

How many miles are the maintenance items, like spark plugs, distributor cap, distributor rotor, and air filter? What spark plugs are installed on the car?

I replaced the spark plugs,dist cap,air filter, rotor and fuel filter 2000 miles ago. I installed ngk spark plugs.

Did you pull these parts and take them to the parts place to be tested as it "sounds" like the car can't be driven.

Anyway, once the car shuts off, leave the key in the on/pos II. Test for voltage on the BLK/YEL wire going into the dist.

Do you have a timing light? If so and you have have 12v to the dist on the BLK/YEL wire, see if the timing light lights up when you try to start.

Yes I did take the parts into have them tested. I have 12.27v to the yellow/black wire after the car shuts off. And the timing light does light up. Thanks for the help.

? after it starts
 

After you get it to start, how does it idle?

I have a 94 with the same motor and am having a similar issue with mine. After mine starts the rpm drop to a rough idle after it warms to 4-500rpm then drops more and stalls. I can continue to give it gas and drive it...but it stalls anytime.

If its a rough idle there is a IACV on the back of the throttle body that you may need to clean the screen on.

Mine is still idling rough and stalling...but I have read the IACV can be common issue

Once it starts it will rev to 2000 rpm then drop down to 700 then it dies. I cleaned the screen on the IACV when I got home yesterday and it seemed to start easier but still has the same problem. It did run for a little bit longer than normal about 30-45 seconds.

When it does this, does it start right back up and go thru the same cycle?

Yes it will do the same thing for as long as you want to turn the key.

Can you keep it running by giving it gas?

Has there been any recent work done to the car besides what you have listed (tune up and testing a few things).

Sounds like what is happening to mine
 

I unplugged a vacuum line on the driver side of the manifold that runs against the fire wall. There are 2 metal tubes against the firewall, the 1 that it was hooked to continues a 3x8"ish canister. I simply hooked it up to the tube that is open on the other side.

This is NOT a fix...just a band aid. My CEL has not tripped, but it keeps it from completely stalling.

I commute 100+miles a day to work...this is my Daily driver. My truck gets 10 mpg do to low gear/big tires. My car runs great, just doesn't idle

Have you tried to set the base idle. Disconnect IACV and open/close air bypass bleeder (TDC of throttle body intake) to get about 550 +/-50 rpm. If this is not possible, you may need to adjust the throttle plate stop. I understand that you adjusted this earlier (should never be touched!). I would set air bypass bleeder to mid position and adjust throttle plate stop to achieve the spec rpm stated above.

good luck

If i try to give it gas it stalls out and dies. Nothing else has been done to the car besides what was stated.

I got you mixed up w/ another poster. If you haven't adjusted the throttle stop screw, try the base idle adjustment.

Also you need to clean the ports the IACV uses to bypass air around the throttle plate.

good luck

1996 accord has no power under acceleration
 

Hello all, I have been having some problems with my accord. With help from this site the car will now start but has no power while accelerating almost like a lack of fuel or too much back pressure. I am not sure where I should start. My gauge is not accurate but I have consistent fuel pressure up to when the engine shuts off. Thanks to all that have helped with the ongoing process.

please do not start a new thread with the same car......
