FUCKIN' SWAP PROBS!
 

Okay lemme start from tha beginning. I have a 90-91 Integ LS B18A1 in my car. My CRX is an HF but the wiring has been setup for an Si. The engine harness is an Si with a few mods made to work for my motor. Everything is set, all plugged up and everything. I start the damn car and it turns over but won't fire. The injectors has each been tested with the 9-volt battery test. They all work. Then got a new MSD Blaster SS external Coil cause the first one was literally bad. Then did the spark plug test where you pull one of the plug wires off and insert a plug to see if it sparks. Guess what? No damn spark. Could it be the distributor? Did I do something wrong? I NEED HELP PLEASE!

Thank you.
Winston

Re:FUCKIN' SWAP PROBS!
 

the Si and HF dist plugs look 100% the same, except some wires need to be moved around. (im like 70% sure of this)

Re:FUCKIN' SWAP PROBS!
 

Is there a way of showing which ones that need to be moved around? And since I've already tried to start my engine a few times already, would I have to start over at TDC?

Re:FUCKIN' SWAP PROBS!
 

Okay, my bad folks. I spoke to the guy who sold me the car and he said that the main wiring is still set for an HF. But the engine harness came from an Si.

Re:FUCKIN' SWAP PROBS!
 

i didnt do ANY wiring mods for my B18 swap in my HF...well i may have cut off the EGR plug, but just cuz it was annoying me....

ill bet ignitor is toasted...swap it out for the one from your HF/Si distributor....

Re:FUCKIN' SWAP PROBS!
 

si and hf engine harness's are different. It will throw a code cant remember which but this happened with my hf when I tried to run a si harness.

Re:FUCKIN' SWAP PROBS!
 

i had to extend 1 plug, and the map sensor wires for a b18b1, but im pretty sure it should all match for the a1...it should be pretty straight forward for the si harness. if u have it all set, i would bet its somthing in the distributor, like the ignitor (like turbohf said).

Re:FUCKIN' SWAP PROBS!
 

I don't think there's an ignitor problem cause I'm running an external coil and the ignitor was removed from the dizzy...Unless you're supposed to leave the ingitor in the dizzy, are you?

Re:FUCKIN' SWAP PROBS!
 

when I did my b16 swap I had this same problem, it turned out that I had 2 ground wires coming from the ecu that weren't grounding. go through your whole ecu wire harness with a test light and make sure everything works.

Re:FUCKIN' SWAP PROBS!
 

Okay, my friend and I are gonna work on this ---- tonight and I'll keep you guys updated. In the meanwhile, keep the advices and suggestions coming. Thank you guys.

Re:FUCKIN' SWAP PROBS!
 

Doh!!! You hafta leave the ignitor in the dizzy...the ignitor is obviously just that...it tells the coil when to discharge. An external coil just holds a larger spark charge. The ignitor is what tells the coil to fire it though. Put the ignitor back in and you should be ok.

Re:FUCKIN' SWAP PROBS!
 

the ignitor is the little guy with 4 wires going to it...it stays in the dizzy...

Re:FUCKIN' SWAP PROBS!
 

Do you have to wire up the ignitor or can you just stick it in there and let it sit?

Re:FUCKIN' SWAP PROBS!
 

take your cap off, then theirs like four wires connecting them to the ignitor. take those off and I think theirs like 2-4 screws total (probably philips or like a hex screw) and then you can then pull it right out. Its not hard should only take a couple mins to do it right.

Okay, THAT'S IT! My buddy couldn't come cause he's baby's born (Congrats by the way...) but I really do need help now, and if there's someone in the San Diego area that's willing to help me out on my frickin' car, I'll pay them cash! Any offers per hour?

Re:FUCKIN' SWAP PROBS!
 

Well , my buddy finally came to see what's up with the dizzy. He says its "acting weird." I do not know exactly what he means by that but he's gonna take the dizzy and stuff to his shop and test it on another car. If it don't work, then I'll have a new dizzy. If does work on the other car, then I'm ---- outta luck. We even changed the damn ignitor to a newer one and it still didn't work. I don't know what else to do... I need to find someone with a white plug dizzy. Any takers?

Re:FUCKIN' SWAP PROBS!
 

Alright, the Dizzt was tested and he says it worked great! But the problem is that my car will not start still for some reason. My check engine light is not coming on. Could it be my harness?

Re:FUCKIN' SWAP PROBS!
 

whats it doing now... ?

Re:FUCKIN' SWAP PROBS!
 

It just turns over but still no spark. My friend from my old crew said that I need the HF harness, not the Si Harness, which I have. AARRRGGHHHH! I guess I have to keep looking. If anybody has an extra HF engine harness, I'll be here or the ad in the "For Sale" section.

Re:FUCKIN' SWAP PROBS!
 

I am just ready to give up on this project its beginning to piss me the fucc off, I swear. So get your money ready soon folks, I might just sell this bitch for a car that actually runs...

Re:FUCKIN' SWAP PROBS!
 

the HF/Si harnesses look the same but have different pin locations for some wires.

Get a 88-91 civic/crx manual and go through the wiring diagrams.

Re:FUCKIN' SWAP PROBS!
 

i bet you anything you havent swithched the 2 white wires around..maybe thats whats causing the no spark in your car...or take it to a honda guy who knos about this type of ----...

Re:FUCKIN' SWAP PROBS!
 

HF and Si harness is the same thing (just added some plugs for EGR and stuff)

On my first swap I had the same problem, and spent 4 days tearing everything apart. Turns out the ECU ground on the thermostat housing wasnt grounding right due to some corosion and me not tightening the wire down properly...

Check to make sure your ECU is powering up and going into its initial diagnosis mode when turned on (check engine comes on for a sec or two when key in the iginition reaches on position)

Re:FUCKIN' SWAP PROBS!
 

Sorry dude, but they are NOT the same harnesses. I've done several swaps throughout the years, and I got stung one time doing one. A customer brang me a Swap for his HF, I figured I would save some time by swapping on a extra CRX SI harness on the engine we were putting in. Well, we put the engine in the HF w/ the SI harness and the thing would not start. It had like 3 or 4 different codes, I started looking at colors of wires on the main plugs and they were in fact different. We swapped the SI harness out with the HF harness (the one that came out of it) and it fired right up with no codes.

So reguardless if they are both MPFI, the pins are in different locations. IF I were you I'd swap the HF harness back on if ya still got it. Because you may run into other problems.

Re:FUCKIN' SWAP PROBS!
 

Wellll Excuuuuuse me ;D
I mis-read thought that he had only had an hf harness, not an si in an hf.....in that case get rid of the si harness its messing you up

When I said they were the same I meant that they accomplish the same thing and you dont need to be removing it. Hf has a bunch wierd stuff added in for EGR crap and such...

^^^
Do what he said

Re:FUCKIN' SWAP PROBS!
 

Thank you jeff I keep telling people hf/si harness is different not a soul wants to believe me. Did the same thing and came up with 2 or 3 codes I believe. Check your grounds check your grounds and if you give up on it I'll buy the car.

Re:FUCKIN' SWAP PROBS!
 

Just making sure clear info is getting to our users ;)

Re:FUCKIN' SWAP PROBS!
 

the only difference in the hf and si harnesses that i know about is the ignitor wire, the si has it on the pass shock tower, the hf is on the drivers, you need to run the white wire from the ignitor at the dizzy to the drivers shock tower, i have a 89 hf and am using a si harness. heh i couldnt belive i had to figure this out for my self like a year and a half ago. thank god for pinouts

hope this helps

Re:FUCKIN' SWAP PROBS!
 

Odd, I remember having like a coolant temp code, Intake air temp sensor code, TDC code and all kinds of ---- with just a crank.

Re:FUCKIN' SWAP PROBS!
 

So basically, I need to get an HF harness right? I'll see who has one first...

Re:FUCKIN' SWAP PROBS!
 

ebay is your friend

Re:FUCKIN' SWAP PROBS!
 

well an't this some ----.

snobs...

im having the same problem no buddy ever postedback like that.

*CURSE, CURSEBEEPyou BEEP!! MOFO!!BEEP!

i would like how it goes im having similiar problem with my d15B vtec swap converted to obd1.
running P28 , with a D15b vtec ( VTI )with the VTI dizzy.

no spark haven't tested dizzy on another working motor...since there an't nobody with SOHC engines... that i know. :-(

Re:FUCKIN' SWAP PROBS!
 

Hey falkhen, my friend tested my dizzy on a 90 integra. It didn't have to be on a SOHC motor...

Re:FUCKIN' SWAP PROBS!
 

Ok guys this happens alot on swaped engines. There are two (2) white wires that go to the dizzy. One is the igniter and ther other is some other random thing. Now if you get these switched this will result in no spark. Try that. It has work everytime a car doesn't start. I will check back and see if that was it tomarrow.

Re:FUCKIN' SWAP PROBS!
 

ok the twin cam run dizzy i figured it wasn't possible, but hey nothig is impossible.

CRXRX7 did that allready..Nada zero zip.. i though it was the 2 white wires... 02sensor and Crank sensor.

i did step by step continiuity check in that all wires when from the correct Pin to the right sensor location. even checked for voltage..this is where its funny.
1.15 volts and it drops as the engine is cranked over
this is good becuase that proved that igniter diode is good. ( does not mean the ignitor is good ) if it was 10 volts or more the ignitor diode is bad and you replaced the ignitor ( according to HMS Honda service manual)
now that i have cleared that the ECU can be at fault if there is no problem with the Crank trigger pick up circuit....which i don't know. until i test my stuff in Runing civic i wont know.

i did get funny readings of the coil and replaced that
still nothing i need a running civic for a guinie pig
only OBD1 may apply ( in the area of Seattle )

PS:my datsun is old ad gets SHITTY mileage 15.7mpg :-X
i need my civic to drive ;)

Re:FUCKIN' SWAP PROBS!
 

hey winston you cant use that si wire harness with the hs crx. Without modifications that is, the car wont even start, get the hf harness man
mike

Re:FUCKIN' SWAP PROBS!
 

well still no news on my ignition problem but i have eliminated the ECU.. to day....

its a p28 with chip in it... i bought off of ebay.. i made it switchable..stock/Chipped Mode. ( i fixed the exhisting switch. )

in stock mode sounds good. ( like stock ;) ) but in chipped mode sounds like a grumpy old man. ready knock your teeth out. ;D ;D
the kid i got to test my ECU imeaditly offered to buy.. lol..i sadly i said "NO!".. feeling sorry for him i offered to sell him my P08 ECU ( that has a bad volt regulator ( after i repair of course ) and is unchipped. this will make more power and has higher rev limit.(8k)..( problem is geting them Voltage regulators )

i still need to test my Dizzy.. its starting to look like im going have to rewire my harness.

well i need just to get the SOHC vtec engine harness and adapt it to Obd0. that should make things easier.

Re:FUCKIN' SWAP PROBS!
 

Hey Mike, know anyone with an HF harness?

Re:FUCKIN' SWAP PROBS!
 

I've been saying that from the begining of the post, no1 listens to me :'(

get that harness!!

Re:FUCKIN' SWAP PROBS!
 

Hey everyone! I just wanted to thank you all for the help and experience of your collective (sometimes argumentive) minds and helping me finish my project. I am happy to announce that the car is up and running. I just need with everything else...

- Another Integra LS ODB-0 Dizzy
