HONDACIVC93

alright some background, i was on the dyno 2 weekends ago and ran into problems and ended up replacing my coil . thats really the only problem ive ever had with this car since i bought it from the orginal owner.

car is a 1995 civic EX with a y7/z6
57trim 60/63
450cc injectors
tuned on crome

drove it home 250 miles and drove it around town everyday like i always have and havent had a problem. so im going to leave my parking spot at my apartment and pull up to my garage to talk to my rooomate and it dies as i stop. turn it over and it will not start. if i feather the gas and keep it running it will run but wont go above 3 grandish and just surges all over the place.

no smoke when its running like its burning oil and it smells pig rich. like fuel dripping out of the DP almost.
i checked my timing belt and it looked like it was a cog or two off? i adjusted it and it still will not start.

plugs look alright other than being covered in fuel but i cleaned and dried them off and theres no difference.

i have spark on all 4 cylinders and im pretty sure theres power to all the injectors.

i cannot figure this out and i need my car! please give me any kind of ideas!

when you adjusted your timing belt, did you do it correctly? double check to make sure you didnt time it 180' off.

HONDACIVC93

no its dead on.

obuhmyuh

definitately a dizzy/timing related issue. i doubt its your injectors. just pull the injectors to make sure they're spitting, if you're gonna check em.

id check ur dizzy first though, seeing as that was the last thing you worked on.

HONDACIVC93

someone commented that my J1 on my chipped ecu might be disconnected? does that sound like somethign that would happen?

obuhmyuh

meh, i doubt it, generally cutting the j1 would result in the chip not working and the ecu running on stock defaults/basemap. a damaged j1 would make it so your chip doesn't work anymore.

HONDACIVC93

but then wouldnt that make it dump a ton of fuel becuase of my bigger injectors and basically make it run like **** like its doing?

obuhmyuh

yes, that would actually explain a lot. your engine could be flooding, and when you give it gas at idle its burning some of it off. you didn't mention you had bigger injectors...

try swapping either swapping your injectors or open up ur ecu and see if the jumper above your chip is damaged or burned. i know someone on here that can fix it for you, if you dont have a guy.



in this picture its that really thin piece of wire (im never allowed to touch a soldering iron again after what i did to my ecu, this pic is just for reference)

HONDACIVC93

hmm that really sounds like that might be it now. i wonder how that happens? is this common?

obuhmyuh

if someone kicked ur ecu or something shorted out, or someone didn't install the jumper very good, then it sure could be common.

HONDACIVC93

hmm well im gonna check that here tonight, thanks for your help so far.

HONDACIVC93

J1 is fine, i even tried a different chipped ecu with my .bin and it doesnt work

2redstars

are you using a resistor box or inline resistors? if so maybe a connection is bad.

HONDACIVC93

yeah i am and i thought about that but they are all soldered and still connected.

HONDACIVC93

so i tested the coil in the dizzy and it ohmed out bad. i replaced it, and it still runs the same ! WTF?

i pulled j1 and converted it back to a p28 and it ran better then it did when it tried to run my tune. with 450s? it at least seemed like it was hitting on all 4 cylinders then

obuhmyuh

when you say cog, i would assume you mean you jumped a tooth? if so, did you take your belt off and make sure that it is 100% spot on timing and put it back on?

HONDACIVC93

timing is dead on. i didnt take the belt ALL the way off but its not really necassary.

HONDACIVC93

turns out a few of my wires on my motorola 2.5 bar map sensor had corroded almsot completly off. but no check engine light? idk, but i plugged in a stock MAP and reburned a chip and its good to go.

drtysohc

Weird. It should have thrown a code....at least you would think.


Glad you got it fixed

HONDACIVC93

thats what i thought. you would think it would throw a code, but for whatever raeson it still works

is that 74 HC373 chip backwards?

obuhmyuh

prob, i dont know **** about chipping ECU's
