ima try my best to explain this.here i go...i own a 1991 honda crx si with an obd-0 b16...i was drivin 3 days ago on the freeway goin about 80 when the rpm suddenly dropped when it got to 5 rpms..then 2 seconds later comes back up to 5 rpms.so i didnt think anything bad.then yesterday.i went to my car to warm it up.i started the car and 5 seconds later.the car turned off on its own.so i was like wtf.i tried to start the motor and wouldnt turn on.i gave it about a minute.then it started.i took it out for a drive on the street.i got to maybe 50 mph.and the rpms dropped and the car turned off.its been doin this and i cant figure out whats wrong with it.it doesnt throw any code. so if u guys can really help me out.i would really appreciated.i hope i explained it well.........thank u guys

 

did you do the swap your self, it sounds like it could be a loose wire, it always makes it harder with no codes

 

i did the swap 2 years ago and had no problems till 3 days ago

 

well im not sure i would say that the best bet would be to check all the wiring make sure its not loose.. also does it drive fine up to the point that it drops down?

 

yea.it drives fine then that problem happens

 

can anyone please help me..i wanna get my car running this weekend

 

check your water temp. sensor

 

your best bet will be that some wires got rain on and are causing a false ground or something i had the same proble my rpm will drop when i hit bump or something and it was a wet wire that wasnt grounded right from the harness.

 

ok.thanks guys..ill do that 2morrow morning...anyone else?

 

give it a good visual and wiggle inspection.

 

just to let u guys know..i changed the fuel filter and im gettin spark on all 4 wires

 

the brushes on your alternator could be wearing and causing that too but i dont know if that would throw a code or not becuase mine didnt.

 

check your main relay. happened to me a month ago, car was idleing fine on its own then suddenly died. it never started again.

checked everything and all seems to be perfect except i replaced the main relay with a brand new one and car works perfect till now.

 

ok.thanks dude..ill check that 2morrow.if anyone else has anyidea.please post here..thanks for the help

 

the next time it is running try to tap the dizzy with a screw driver and see if it shuts off? it could be that that happened to one of my boys

 

 

check your ignitor...if you can afford it just replace it...if its old or a parts store one it WILL eventually go out anyways....on a side note...GET A GENUINE HONDA ONE!

i was told by 3 guys today its the main relay...and 1 guy said igniter..how much is an igniter?...thanks guys

dont quote me on this...but if I remember right around $75...

does the fuel pump prime when you turn the key to the "on" position (can you hear the fuel pump?

 

yeah.i hear the fuel pump

 

check all your wiring that you might of changed. I recently switched back to dpfi for smog, now that the weather is getting hot my electrical tape is coming off my wires and i had one wire come apart and my car ran like ****. That main relay and igniter stuff sounds good too. Good luck.

 

got it..thanks guys..hope i figure it out..i really appreciate it

 

good luck with that. i have a simaler problem right now. cant wait to hear how yours goes. unless its bad ofcoarse but i got a new ignitor from my local honda swap shop and they sold it for 40 bucks but they had the parts lying around good luck with that

In my expeirence...if the fuel pump does kick on...its typically not the main relay...

like another said its getting warmer outside...and ignitors tend to fail when it gets hotter...
