Ok here I go. I got te CRX about 7 weeks ago and its been acting up. 90% of the time it starts and runs fine. But other times mostlly after its been runing it will crank and start but then stalls. If I try to crank it it jus turns over and woun't start. If its left alone for a while it will most of the time start up and be fine.

I know it has spark, I know it has fuel presure.
I think the injectors arn't firing.

I changed the injector resister modle and same problem.

I'm going to change the o2 senser ASAP

motor Mods to car are
cold air intake with new filter
4-2-1 header
catback exhaust
thats it


Please help I really wan't to make it to NOPI this year.

 

troubleshoot and pinpoint the problem before you throw parts at it.
i bet if you removed your main relay and desoldered the ckt board, then applied new solder your car would start every time. maybe you have a "dry joint" in your main relay.

 

are you sure you are getting fuel? I had a problem like this and it was my main relay, powers the fuel pump.

 

i had this problem and it was a temp sensor......it wont be your o2 sensor it just measures air and fuel you could unplug it and you car will start ... most likely main relay or temp sensor

 

Any CEL's? if an injector wasnt firing it would throw a code, happend to me and it was throwing code 16 which is fuel injectors, but i agree with the above comments, could be your main relay.

 

OK I took it for a ride and got back home and cut it off and tryed to restart it and nothing. I didn't hear the fuel pump kick on so I guess its the main relay. Now to try to figure out how to fix if. I got a Honda delership repair book so I should be able to fix it.

thanks

 

There are a million posts about fixing main relays, do a google search and I bet you will find the nice one with pictures I used a couple years back with a non-starting car...
