HEY, I NEW HERE AND I HEARD YOU GUYS ON HERE NOW JUST ABOUT EVERYTHING, LOL. SO I NEED YOUR HELP PLEASE.
OK, I JUST BOUGHT THIS CAR ITS AN 89CRX SI WITH A D16Y8 SWAP. I GOT IT AND IT DIDNT RUN. I PUT A NEW ALTERNATOR ON IT ( IT WAS FRIED) , BUT I ENDED UP PUTTING A NEW EFI MAIN RELAY ON IT AND IT RAN. THE GAS THAT WAS IN THE CAR WAS PROB 6 MONTHS OLD SO I PUT NEW GAS IN IT. THE FIRST NIGHT I HAD IT OUT IT RAN FINE IT SEEMED. SECOND DAY IT WAS PUTTERING REAL BAD AROUND 3000-5000 RPM'S WHEN I WAS DRIVING AND IT ALSO LOPES ON IDLELING. I ONLY HAVE BEEN DRIVING IT FOR LIKE 4 DAYS. THE LAST LIKE 2 DAYS THOUGH THE CAR WOULD RUN LIKE ****. I WOULD TAKE OFF AND WHEN IT GOT TO LIKE 2500RPM'S IT WOULD ACT LIKE IT WAS HITTING A REV LIMITER AND LOOSE ALL POWER. THIS MORNING I WENT TO GET BREAKFAST AND ON THE WAY BACK I WAS LEAVING A STOP SIGN AND IT WOULD BOG AND PUTT AND WOULD BARELY HAVE ENOUGH POWER TO TAKE OFF SO I PULLED IT INTO A GAS STATION AND WHEN I LET OFF THE GAS IT JUST QUIT. NOW IT WONT START.
THESE ARE THE THINGS I TRIED.
- NEW CAP,WIRES,PLUGS.
-IT HAS A NEW MAIN RELAY
- I TOOK THE O2 SENSOR OUT TO SEE IF THE CAT WAS PLUGGED.
- NEW FUEL FILTER AND FUEL PUMP WORKS.
- MESS WITH THE DISTRIBUTER TIMING.
- PLUGS ARE GETTING SPARK BUT NOT MUCH
-ECU NOT READING ANY CODES AND NO CEL ON

PLEASE HELP, I DONT KNOW WAT TO DO.


ALSO. THE D16Y8 IN MY CRX HAS THE VTEC SYLINOID BUT THERE IS NOTHING PLUGGED INTO IT. I NOW THE STOCK CRX'S DONT HAVE VTECH SO THERE WOULD BE ANY WIRES FOR IT AND IM NOT SURE WHICH ECU I HAVE. SOMEONE SAID TO FIND THE PIN IN THE ECU THAT DOESNT HAVE NOTHING TO IT AND RUN IT TO THE VTEC. ANY HELP HOW TO GET THE VTEC WORKING WILL BE GREATLY APPRECIATED.

( updated )

i finally got the car back to my house. i looked at the distributer and didnt really noticed much of a burnt smell but the posts in the cap where kinda white and had some indentation. the far left wire was loose on the igniter so i crimped that on put it back on so it fit tighter.

things i done/ checked this time
- swithced ecu's ( both pm6's)
- switched injector resitors
- clean and sanded the distributer cap
- has new fuel filter
- pump still wotks fine
- spark plug wire getting some spark
- took the cat all the way off in case it was plugged.
- tightened the loose wire on the igniter
- main relay works

when i crank the car over for awhile the car will knida start up but it just stumbles around and quits within like 5-8 seconds. i know its getting fuel and there is a strong gas smell but i think thats cause i have the cat off now. it almost seems like i flooded it like you would with a dirt bike. i couldnt find my socket for the plugs so i couldnt pull them. also i am getting my parts car tonight which is 89 crx si but withg the stock motor. the intake and distributer are the same though.

- the ecu in the car now is a pm6 which is the stock crx si ecu. i heard the d16y8 ecu is the pm7. so right now there is a pm6 running my d16y8. how bad will this hust my performance and i will have to find the d16y8 ecu to run my vtec, right?
how do i hook the vtec up?

thanks for the help!!!

I am sure you changed the oil and checked to see there is enought. I am not sure about it but I just hope that engine is not blown. But here is a bump for you. Btw don't right with caps people get very annoyed by it and might not answer you question.

Dave

oh and welcome

 

thanks for the bump and sorry about the cap, lol.

yes there is plenty of oil. that would be shitty but i have feeling its something stupid.

 

im not for sure, but it could be a map sensor, my friends sentra had a similar problem as well, the rpm would just bounce when it hit 3k rpm.

 

sounds like a ignition or fuel. Yea this a bitch. Swapped car with god knows what ECU is in there. Take out the passanger side carpet, and look to see what ecu is in there. What model was the car anyway (SI, DX, HF?).

 

thanks for the tips, i will try them tonight.

i updated the post now too

 

bump it up

 

easy fix for your problem. Get a obd1 p28 ecu. That ecu that you have in there doesn't have the circuitry (sp?) for the vtec and other sensors for the engine. You need to get a P28 with a conversion harness and change all the engine sensors to obd1

my friend has the same engine in his crx and his runs like a charm but his is a 91' though

 

You need to start by getting the right ECU in there. Problem is it sounds like whoever did the swap did a **** poor job and most likely kept the old CRX harness... You can do that, thats fine, but it needs to be modified for the Y8. You need to get EVERYTHING properly wired up and also get the right ECU in there. The ECU alone could solve your problem by actually supplying the correct amount of fuel!
