i have a 94 accord lx 4cyl. automatic. Now the problem is the car was running fine, until I changed the battery. Then went and started it, no problems. Went out the next day, and it wouldn't start at all. I have checked the battery terminals, replaced the spark plug wires, and cap and rotor. I've checked all fuses, as well as the main relay. Ive noticed its not getting spark and no fuel also. How many relays are there that control spark and fuel pump? Any other ideas to what it could be? Is there another ground wire on the motor that i might have missed? Any ideas or help is well appreciated.

Thanks

 

The D4 light is flashing, and also i have some codes, but can't remember which ones they were. Ill have to check again.

 

I would try another main relay.....if you need to go grab a couple out of the junk yard even ( its nice to have spares anyway ). A faulty main relay will cause issues like this. Could also be the ECU though. Haynes manual has a flowchart for starting issues, takes you through every step very easily. I used this process on a DA integra years ago to determine I had a bad ECU. GL

 

I tried a friends relay, and i know it works, i just pulled another one out of my hatch to try that too. Im not getting a code for bad ecu. But ill check the codes again.

 

Ok i was looking online and found this. Can anyone explain where this is? Do you think this could be the problem? And where could i get one at?

It is the Ignition Control Module, This is a common problem with hondas. sometimes the car will start fine and sometimes the car just won't start. The Module is a silver box located above the steering column, behind the dash. It costs 55 dollars and only takes about 10 minutes to change.

 

Mmmm..... My ignition switch went out before and nothing would happen when i turned the key and all the auxiliary lights would stay on when i would try to start it, so i know it wasnt the battery. It is very common in hondas and especially in accords dont ask my why they go out.

 

Do you have to reconnect the terminals after every time you try and start it?

 

^^ No, the car turns over. Its just not getting spark, or fuel. Well, i guess ill try for fuel again. I disconnected the return line.

 

ttt anyone?

 

check the fuses under the hood, theres a 15 amp fuse thats the ecu fuse, it will cause no fuel or spark but will crank. check every single fuse,

 

Ill check them again. Will the Ignition control module cause no fuel also? I know it causes no spark?

 

if by ignition control module you mean the main relay under the dash on the drivers side then yes if thats bad you will not have fuel

 

on my 90 civic the ignition control module is in the distributor. Just had mine tested today at autozone. it was good. Can't figure out why my car won't start either, but I AM getting spark and fuel. Bout ready to explode!!!!

 

To the OP, the Ignition Control Module is used to control the ignition coil. The ignition control module recieves a timing signal from the ECM so it knows when to correctly time the spark. A failure of this will cause no spark. It will NOT cause no fuel.

No offense, but, how exactly are you determining the vehicle is not getting fuel into the cylinders?

Does the check engine light come on when you turn the key 'ON'? If you turn the key to the 'ON' position without starting the car does the check engine light go out after a few seconds?

 

Is the ignition timing correct? Just because you're getting spark doesn't mean it's at the right time. Also, same question. How are you confirming the cylinders are getting fuel?

 

When I pull the plugs, there is definitely gas on them. And the ignition timing is correct. I guess we'll do the timing belt again for the hell of it, but 90% positive it's correct also. The dizzy was checked at autozone and they said it's fine. has new plugs, wires, cap and rotor. All we did was swap out a bad head for a "good" one i bought off craigs list that looked immaculate. Car ran before the swap. Seriously puzzled on this one.

Sorry for thread jacking :/ but at this point I'd rob a baby if I could figure out my problem lol

 

I cracked the nut on the fuel rail. Pretty much had it off and turned the key back on to prime the fuel system and nothing came out. Had the guy check the fuel pump with a voltmeter and no power back their either. We changed the main relay with two different ones that we know that are fine, nothing. Only thing i can think of, there gotta be a loose ground some where on the motor. Where are the grounding points on the motor located at?

 

ANd the check engine light comes on when i turn the key, and stays on. Also the D4 light flashes.

 

Tstat

 

found the problem, a circuit in the ecu is burned, let me know if anyone have one please

 

Why was the t-belt replaced- I hope it was before the old one broke?
