Icon8 wire pinched?

92 prelude with h22 motor 5 speed tranny

I just bought this car knowing it has an intermittant problem.

Problem is sometimes it will not run. Will crank all day just will not run. P.o thought it would of been fuel pump as the fuel pump is not priming. Change of fuel pump nothing changed. Test of old fuel pump shows its still working.

Then someone spliced into an injector wire and when it wouldnt crank you grounded this wire which in return would allow you to crank the car and it would work normal for a random perios of time. Sometimes a few days. Sometimes a few months.

Now it wont crank at all unless i leave it grounded which still wont work as it opens the injectors wide open and dumpa raw fuel through the exhaust.

I got a main relay from the junkyard but it wont even crank the car at all even with that wore grounded. So im guessing its completely bad. Talked to a buddy of mine and hes thinking it could be the ecu. Still havent ruled out main relay yet either.

Since it only happens randomly im taking a guess and saying that maybe a wire got pinched somewhere and certain bumps cause it to happen? I have no clue. Im a chevy truck guy. Or really just a 4x4 guy.

Help me out as i wanna get vroom vroomin lol

Re: wire pinched?

It seems like you found your problem, replace the sliced wire.

Re: wire pinched?

No this wire was spliced in. It isn't a normal wire.

Re: wire pinched?

Well wouldn't it make sense to replace the hack job electrical and replace the sliced wire with a new one?

You only posted the thread today man.

Re: wire pinched?

I know i just put the thread up lol.

The wire was only spliced in. If the wire isnt touching anything its as if it isnt there. The wire didnt replace or take away anything so instead of possibly conpounding the issue im leaving it be for now. I know the wire has good connection right now so i decided to leave it till i find my issue.

Re: wire pinched?

And idk of you read right. Idk if a wire is pinched or sliced. Im just asking if that is a commin occurance on thear cars. If there was a spot to look for.

But the wire in question is sPliced in. Like added to it in conjuction with the original wire.original wire is still there and connected.

I have no prior knowledge of hondas. So i spent nearly 3 days searching similiar issues and testing these issues before i made this thread asking for assistance hoping someone on pz will know a little more about.

Thank you for directing me to those links which i have already looked through countless times. I will go back through them and see if i missed anything though just to be sure.

Re: wire pinched?

who's to say the used relay you got isn't having the same issues as your original one? take it apart and check the solder connections to make sure. I'll try and scrounge up a video of the repair.

Re: wire pinched?

I will do that tomorrow. There was another prelude at the jy so im gunna go back and snag that one as well. Maybe it might be the ticket. If not ill refer to that video.

Is the ecu going to be on the pass side kick panel? And what all model ecus are compatible (if any?)

Also what is the ecu looking thing between driver and pass floorboards behind the radio section?

Re: wire pinched?

na man lol to each his own, i just think it looks funny with oem front bumper and kitted out the rest of the way.

but on the serious note, i had the same problem that your having and it was indeed the main relay. But I would DEF fix that wire that your talking about. I mean it'll only take a few minutes to do.

A sense of hope! Ill try and snag as many relays tomorrow that i can find!

Any idea what the ecu looking thing i asked abt a few posts ago is?

I am thinking abt taking the side skirts off as they are cracked anywsys but the bumper matches the dual exhaust and i do like that. Idk what my plans are yet lol.

I saw a diagram for using a jumper wire on the relay harness but it was for a civic any idea if there is one for a lude? The civic one didnt match up

Re: wire pinched?

in the posted links to our Stickies there is a user repair manual. In said [downloadable and searchable] manual there is a couple pages on testing your Main relay.
One of the specifics is the yellow wire that comes off said relay which is THE power wire for the fuel pump. turn your key on, do you hear the fuel pump prime the system?
No, then using a DMM test said yellow wire at the top of the fuel tank. When you turn the key on does it get at least B+ voltage?
No?
go to the relay and test the same wire the same way. Is it getting power when you turn the key on?
No?
You *may have a bad relay.

**there is MORE testing to do to determine if the relay is the actual problem or if the issue is before the relay. Go d/l the guide and have fun.

Re: wire pinched?

A D-series. Don't fux with em unless you plan on chipping and tuning it. Only ECU that will properly run the (4g Prelude) H22 is a P13, which is only found in the Prelude. Other than that, the next best would be a P72, but they need to be chipped and tuned as well. Runs a bit lean and falls on it's face in VTEC.

Re: wire pinched?

It runs!

Swapped in a ecu for an h22 swapped accord from phearable.net and she fired right up no problem.

Took it for a few test runs and i love it. Idk what was wrong with my original ecu but with the other it had way more power. Coulda been the chip in it as well. Either way it hauls ass.

I took the side skirts off. I will be putting the stck ones back on as well as the stock bumper. Going to add front and rear lip to it instead of that kit.

Also i already scored a new muffler tip to put on it just gotta get the new bumper painted so i can swap it all over.
