I got the engine in, and all hoses and sensors (to my knowledge) connected...but the car isn't getting any spark to start. It's turning over, but there is no spark from the distributer...any reasons? I've already put it all in so I'm not sure why it wouldn't do this...maybe a bad distributer? any one have any ideas? maybe there's something I forgot? I didn't change out the MAP sensor..would that make a difference? It was an H22 put in an Si Honda Prelude. I just used the Si (H23) harness and added the two sensors, and I think I did it right, but maybe not? Any one have any ideas? Thanks.

 

Did you change your ECU?? I am right in the middle of doing the exact same swap, check to see if the engine has a "Crank Positioning Sensor" in which case you'll need an ECU which supports the CPS. Let me know cause i'm about ready to crank mine over too.

 

yea I swapped the ECU with a P13, but I'm not getting any lights, and not sure where that sensor is...heh...I'm not a nooB, but I'm not a pro mechanic either if you catch my drift...I'm not really sure what the prob is...sigh..sucks. Also, did you have any probs with the down pipe? Mind doesn't fit onto the cat back...so right now I'm either looking at a new exhuast to fit it, or maybe just a new header, any suggestions?

 

Ya I did have a problem getting the motor to mount but with some wiggling it mounted into place, what I did was attatch the lower exaust piping to the manifold and it fit right in, well thats an under statment took me an hour to get the engine into the chasis damn crank pulley and tranny kept binding.

The CPS sensor is located by the crank and should have a little 2 wire harness comming off of it, the H23 dosent have any wire harnesses extruding from the crank pulley area at least mine dint, so if it does have it then you have a CPS but if your using an P13 ecu then that should be fine either way unless the P13 is of a 96 and up H22 and the engines an older one then they will conflict and vice versa, you should get the ecu of the same year motor. I think that might solve your problems.

 

well I got it as a package deal from hmotorsonline, so I would think it's all from the same car, JDM H22a, so I think it is. And as far as that sensor goes, I'm not sure I saw it, I checked but didn't see any there...of course this is off memory since I don't have it in front of me. It's not that it won't crank, it's turning over, there is just no spark going to the spark plugs, so it's not getting the fire it needs to ignite yenno? I'm clueless, heh.

 

Oh, also, my down pipe. Mind won't bold up to the cat back, it's larger, and the bolt pattern is diff...maybe it's from a 5th gen? I'm thinking they just took a 5th gen down pipe and sent it with my H22a, so I don't know what to do, I was thinking of just getting the larger exhuast? but will that still fit? Usually that down pipe should bolt right up to the exhuast right? even tho it's from an Si?

 

Well my engines a 99 H22A4 and it fit my 93 just fine, maybe cause your is J-Spec but I dont think it should matter.

And if you dont have a CPS your ecu maybe off a newer lude which had CPS cause its a fail safe which wont allow your engine to start if the crank is out of position or misaligned or if your timming snaps, these are non-interference engines.

Did the ECU come with the motor that you bought. If you got it from an auto wrecker they might of gave you an older engine with a newer ecu not realizing the difference.

 

my guess is that you have a ground not hooked up right. thats what my problem was when i put mine in. make sure the ground on the thermostat housing underneath the vtec soleniod is bolted on. its kind of hidden and you might have forgot about that one. also make sure that you have the right distributer if you have a jdm distributer it wont work becuase you are using the internal coil distributer with the h23 harness which uses an external coiled distributor. hope this helps you out some.

 

That's probably exactly it...I am using the JDM distributer. But since I'll have to switch (I'm assuming) where in the hell am I gonna put the exterinal coil? any suggestions? Thanks.

 

Check and make sure thats you problem, and yes very likley you might of forgotten a ground that a very popular over looked problem.

Check all your harnesses and bolt hoel to make sure you got them all.

Just got new ecu in today so i'll likley have a chance to start it up today and find out if mine goes aswell.

wish me luck!

 

when i was putting my engine in, i couldn't get it to do anything, after days of trying to figure out what was wrong. i found one of the wire connectors that was not fully connected together. After that the car started up on the first try

 

hey HKpowers, did your down pipe bolt right up to your exhuast? mine won't fit...suggestions? you think if I just replace the header it'll work, or will I have to replace the exhuast? Thanks.

 

so should I just replace the exhuast or is there a cheaper way?

 

late response but if you can find a coil mount off of a usdm motor then thats the best way. or you can get a extended coil wire and mount it on the inner fender or something like that. and just for info i have si exhaust and i just bought a h22 header and it bolted right up. i think the problem you have is you are mating jdm with usdm and it doesnt always work. hope this helps you out and let us know what all your problems were.

 

give me $23 and some booze - i'll get that bitch runnin

 

haha, if you were in the area I'd give you 40 bucks and some booze, lol. But naw, I do think that the JDM and USDM aren't working together, which blows...so I guess my only alternative is? all new exhuast? any one know? I live in a City where there aren't any emission laws. So what I'm thinking about is getting headers and a high flow cat, then just a straight pipe...yea?

 

Yeah just go custom with a reputable shop or if your experienced.

 

Sorry for the later reply my computer was down.

Ok well my exhaust bolted right into the downpipe. Not sure why yours wouldent.
Did you ever get it running?

 

yep yep, it started alright, I had to change distributors before it would even turn though..I still don't know why that is...did you have to? hmm...anyway, my exhuast won't bolt up right...the bold pattern doesn't fit...maybe because it's JDM to USDM, I have no clue, but oh well, I'm going to get some good stuff soon enough, haha, well just some straight pipes, after the cat back that is, fun fun.

 

you know what today we finnished up everything and stupid me thought the exhaust would bolt into the down pipe, I mean it looked almost the same untill I went to connect the 2 and they also dint fit, the h22 is much more wider than the bolt pattern on the down pipe, what i'm going to do is this, remove the down pipe and the header and cut the header off right at the flange then weld and extension pipe and clamp it down onto the down pipe, that will work untill I can get the right down pipe or after market header.

Damn I was so sure it would fit!!.

and i'm not sure why you have to swap the distributer I had to do it too.

Oh and on the bright side the car started with ease and purrs like a woman right after giving it to her good!

 

yea, my exhuast won't bolt up either. It does start though. I had a HORRIBLE accident though. One of my lugnuts on my rims stripped or something, but the entire TIRE fell off, I think my buddy just didn't put them on in right order so it wasn't balanced right. So I just got tired of it and took it to honda, I'm going to let them take care of somethings...and I'm just going with a straight pipe for right now, until I get new headers and a new exhuast, going to get them both at the same time, it should be great, haha.
