i bought a 89' hatch and i have no clue what wiring harness i have so if anyone can tell how to distinguish it i'd really appreciate it.

also i just put in a d15b7 in and i am running a virgin pr4 ecu so i have the following problems:
1) no spark but i have no idea what dizzy i am using
2) i only get one click from the main relay
3) i have a cel that i can't jump if my life dpended on it, and i have tryed with 2 diff. ecu's
4) the fuel pump is getting just about 5 volts, i tested it by putting a volt metter to it and it only gets power when i turn the motor over, otherwise i don't get anything
5) i check continuity and only one wire has power all the time when the key is on and while i try to start the car

all the help is greatly appreciated,
Nick

to check the dizzy u r using..check the ingraving on the housing...
google the code and it will tell u what u got..
did u use the wiring from the engine or u re-wired it...
check your grounds...specially the on thatgoes to thethermostat....
check starter..isur battery good...theres alot of possable things....

well on the bottom of where you bolt it up at inbetween the webbing is d-2426 and that is the only number on the whole thing besides what looks like a home-maid inventory number b/c it looks like it was put the by a dye grinder, and i am using the wiring harness that came with the car and i think he was running a d17? all that came with it is the block, i will check the grounds and tell you if that helped any, and yes the starter is good and hooked up right and i have a good battery

well i have the only 2 that i can find inside under the dash grounded, the ones that go to the underhood fuse box and i have 2 grounded to the starter b/c there is no slack to pull the one to the thermostat but i did have the 2 on the thermostat and i have the same thing, i also have 2 what look like relays grounded to the bay but i don't know what they are for. if there are some that i am missing i don't have b/c i checked a few times

isn't there anyone that even wants to throw an idea out here to help me out

i can fix ur car how far are u from jax?

is ur car converted to mpfi?

if not i got alll the stuff u need to do it

yea ur using the wrong ecu u need a pm6 ecu i got stacks haha

need sum pics so i can see what ur working with

Start by using a better ecu!

You are using a PR4, b series LS ecu for a 1.5L d series engine????

akshn1

use a pm5 or pm9

turbohatchBnuts

a pm5 is a dpfi ecu dont use that

pm9 is for dohc zc

well i've actually read a lot of people running it with the pr4 but here is a site with all the pics on it from the dizzy to the engine bay, and i apprectiate your offer turbo but i'd rather doit it myself i just need some tips on what's wrong

kwell

they run on a pr4 just fine, just make sure you dont hit boost unless thats chipped

well i'm going to the junkyard tomorow, what harness and ecu should i buy to get me reliably running

remember i have a d15b7 with a mpfi mani. and a 89' dx hatch

make sure the wiring on the car was done properly and that you got a resistor box and check if all plugs are getting spark...and go over the engine harness and look for any corroded and fxcked up cables/sensors/plugs
check wassup with your dizzy and plugs and plugs and wire and try running it with a pm6 ecu

However what I would do and is best in your case
try and bring home a whole stock goodlooking engine harness from a civic/crx DX must be DX(make sure to remove it properly and remember where everything goes)
and if you get a chance bring yourself another engine harness(si/hf prefferably in whatever condition(to get missing plugs/wires for a DX mpfi conversion) and a pm6 ecu
and that way get/make yourself a more complete and reliable engine harness(mpfi)
and not have to deal with a shitty beatup harness
