Ok family, I have a 93 accord ex. Yesterday I was driving only after a 1mile of driving, rpm gauge starts jumping around then bam! It cuts off while in motion. Got it towed home, I changed the fuel filter, did a fuel pump check(worked), changed ignition coil and this crap is driving me nuts...other than that car runs great..please help ya boy out on this problem.....

 

Also when I do get lucky, it cranks up then goes off after about 5 seconds....other than that it will only try to turn over but won't catch( stay crank)

 

did you get any CEL? what are the codes? did your D4 light flash?

 

No codes no d4 code...

 

On the thermostat housing, it should have a ground wire bolted to it. Unbolt that ground wire, clean it up with a wire brush or sandpaper, then bolt it back down. That is an important ground for the engine electronics.

Do you have a volt meter? And/or a timing light?

 

This is the therm housing. Is this where something should be that you are talking about or is it located at another area?

 

I do have access to timing light, not voltmeter...

 

Looks like something is missing. But your pic's are from the top....

However someone might have "moved" the ground - if it was missing the car would never run. So look under the t-stat and do as PA suggested.

Then, when the car dies. Does it start right back up or do you have to "wait some period of time"? If you have to wait, this is the time to TEST. Start by checking for spark at the plugs...the tach gets its "signal" from the ICM, so if the tach starts to bounce just before the car dies....I'm wondering if it is going bad once hot.....TEST before replace.

 

Ok.. I did find the ground wire under the thermo housing, cleaned it and put back on. Did more research, changed out the igniter inside distributor and it cranked and drove fine. On another note, my temp gauge goes to the red zone within 2 min of driving. Changed out sending unit and instrument cluster.......don't know what else to check regarding that.

 

Is the engine actually getting warm - IFR temp reader can help here, or if you have a volt meter that can read temps....but those are kind of pricey where harbor freight seels IFR readers for ~$35.

You can try feeling the upper and lower hose for a difference in temp?

Check the single wire from the temp sendor to be sure it isn't grounding on something.


PS- Please add your car info to your signature, so we know what year this is without having to go back to the top THANKS

Really need to know this first before going further.
