Ive had my b18c installed for a while, and just tried to turn it today... the starter kicks in, but for some reason I cant get the motor fully turned over. Now it cant be the dizzy, because we took it apart and tested the continuity and there was no problem between the ignitor and the coil ( no test light when touching the ignitor to the coil and cranking). So we looked at the alt, now there shouldnt be coming from there but going into the alt. Though there is.... somehow I have a positive charge in my block. I have 2 grounds 1. to the valve cover and 2. to the tranny. where are my other ground supposed to be?? isnt there one on the block under the IM??? Where the hell am I getting my positive power to my block from???

there is a ground that will ground on the passenger side of the engine bay. it comes from the engine wiring harness and splits like a little fork, it bolts in right after where your heater water outlet is over under the distributor

no one knows.... wheres poison,villian, voodoo, and Emerica when you need them....

to the top for spade.

Do you have a power steering or a/c ground?

IS3Fifty

took them out spade... it went into the Cx so no need to do all the power steering garbage and I dont care about Ac at the time.

Kewl, how about where the valve cover ground is?
Does it look like this?

IS3Fifty

yep... try again.. I have all the grounds. Wiring and everything done. Im thinking maybe vac seal leak between the IM and TB???

Possible. But the seal leak would create a higher rev.

well I dont have a throttle cable hooked up so I cant rev unless I do it by hand. I am using my stock CX ecu to start the car but it should idle with that computer. my comp hasnt come yet.

I'd hold off on trouble shooting until you get an ECU capable for that engine. Theoritically, the CX ecu should be fine, however you may damage something by running too lean or some of you sensor are in the wrong locations.

i was thinking about that, but I wasn't sure whether that would have a bearing or not. I talked to Marcus from HeelToe, he told me if should be fine to start on but he wouldnt run it anywhere with that ecu. I felt the same way. Technically, all Honda idle is the same right??? so I cant see why it would do that.

Spade

Technically but, you are using an ECU made for a much smaller engine.
Plus the wiring could be different.

What generation ECU/engine?

IS3Fifty

obd1 to obd1

I told you, there should be a ground that comes out of the wiring harness and grounds around below your distributor/water outlet area... check your helms its there, are you sure you grounded it?

IS3Fifty

dude... yes get off that subject. Im not a moron. That was the first ground that was made.

That is what you said. Then you said you have a positive charge on the block. There are three grounds, not two. From what you keep typing you only have two hooked up which would explain your positive charge. If you have all three hooked up you should have made that clear and not said you have 1) to valve cover and 2) to tranny.

IS3Fifty

if you read the whole post you would see that this issue was already cleared up.

Well... now Ive tried a LS ecu and I still can not get the thing to start and idle on its own. There are large "cracks" when attempting to start the motor, as i said before fuel is correct. Im beginning to believe its timing now. Any opinions??

IS3Fifty

im starting to think that there is a problem with either A. the wiring to the injectors or B. the timing. Anyone have any incite?? The motor will start on a cx computer, but would not start with an LS. I am waiting on my GSR comp to get here. It cracks extremely loud, though it is open header. Once I have tried to start the motor a few times, I shut it down and hear a gurgling sound. Intake?? or is that exhaust??
