[sik yellow rex]

ok i swapped an obd1 b16 into my si! used a boomslang harness converter and pr3 ecu.'''' the motor will start on occasion and run eratically jumping rpm revs!and other times it will idle smoothly. but when it starts to run erraticaly it will eventually after dyeing and restarting several times. get to the point where it wont start at all! like it is cutting the main relay out,, i have gone through seven different main relays. and it gets to a point to where it seens like the relay is shot!also when it is running rough the main relay chatters''''''any help would be greatly appreciated! i have checked and rechecked wireing!!!!! all seems to be wired correct. what can be the problem HELP PLEASE? ALSO THE MAIN RELAYS ARE NOT GOING TO HELL BECAUSE AT ONE POINT THE RELAY SEEMS LIKE IT DOES NOT WORK. so i swap in an old relay and it will statrt the car! the pr3 ecu has been socketed and chipped. was this way when i got it from japan.

I know this sounds simple but check all your grounds

 

[sik yellow rex]

but isnt a honda reverse polarity IE ground is power i do not have the motor grounded to the chassis could this be the problem

 

[ef8]

umm you need to have all your grounds connnected

 

[sik yellow rex]

ok ground is not the problem any other ideas this is getting frustrating

 

[ef8]

map sensor?

 

[trainjunkie]

did you check your codes by chance?

 

[sik yellow rex]

yes and it is not throwing any cel codes

 

[ef8]

Check all your vaccume lines

 

[sik yellow rex]

vacume has also been gone through over and over! my boy wants me to bring it too his shop. but i am thinking it gotta be something simple'' and i would hate to pay shop rates for trouble shooting that could be costly!

 

[freak86]

iratic idling could be the water temp sensor, but more than likely it'd be throwing a cel. but not if it's still "within parameters".

check your plug wires make sure they are in the right order

i had same problem it was the ground on top of the tranny make sure its really good it stumped the hell out of me i didnt think a little problem like that would cause such a problem but it took me three days to find it

 

[speedrx]

make sure your ground surfaces are clean sandpaper works can fix many things. it fixed my buddy's gsr

 

[sik yellow rex]

well it is not ground either this is getting rediculous i cant figure it out for the life of me
