well i got eveything installed and wanted to crank it up and let it idle
so i swapped in the chipped P28 w/ jumper harness I bought for my 98 hatch
swapped it in and turn the key first thing I notice was the fuel pump didnt engage hmm turns ove and wont crank

so I swap back to the P2E DX ecu and it cranks right up
of course there is absolutly no engine management so I shut it off and now IM wondering whats up?

why doesnt the fuel pump engage for that Neptune chipped P28?

faulty jumper harness?

 

bought this whole kit
at first I thought he might have had the fuel pump disabled but he never installed the walbro so he was using his stock fuel pump

why doesnt it engage

1998 civic dx

 

the ecu aint chipped right, i've seen that problem before.

 

well I bought it from a guy RUNNING it on his 2000 CIVIC EX boosted D16Y8 w/ stock fuel pump

and put it on my D16Y7 now boosted 1998 Civic hatch DX


any probs there?

 

Where did you get the jumper harness from?

 

bought it forma local guy had it on his car running

any diff from a 2000 Civic EX
and a 98 Civic DX that would cause an issue there?

 

The conversion harness is different. 96-98 civic uses the same one and 99-01 civic uses a different one.

 

anything I can do?
is there a LOT of difference or not really?

so basically my car is OBD2a
and the harness I got from the guy in in the 2000 CVIC EX is OBD2b

right

 

right, you need a obd2a - obd1 harness

 

where can I order one from?

Just do a quick search and you'll find tons of people who sell them. Kenji makes them too, so you can justs shoot him a PM if you want.

 

i dont know how your going to get the iac to work. since obd1 iac's are 2 wire and since yours is a 3 wire iac. just something to think about

 

there is a big difference in the two harnesses...the iacv can be made to work just search around

 

do I need to buy a Y8 manifold or something?
I dunno what to do about the IACV differences never heard of them till now

are you saying obd2b&gt;obd1 harnesses are preset or you have to move the pinouts? i'm guessing you only have to swap the iavc pinouts if you're going from d-series to a b-series right?

my car has been acting kinda funny since i went obd1, and i'm wondering if the harness got messed with and now it's throwing my car off. i think the harness was on a civic before, so i'm curious to know if this would be a problem with my integra?

here is the tread to my problem: https://honda-tech.com/zerothread?id=1413976

 

the iacv needs to be moved in the plug to A12 unless you have a special harness...i think if its wrong you will throw a code
