99 civic with gsr swap won't start, it cranks and gets fuel. I'm pretty sure it doesnt get spark. I had 2 coils that i swapped to see if that was the problem but they're are both good. The ICM was in a running distributor before i took it out. The coil gets 12 volts at the black and yellow wire. There is no volts at the yellow/green wire when disconnected to the icm. I checked the ohms and it gets a 1. The funny thing about all this is when i put everything back together and crank it a couple times, I started to smell the fuel and i went to the hood of the car and smelled something burning (and the fuel) i thought the dizzy fried or something. But it was the negative battery cable that goes to the frame and to the negative battery prong, the cable was very hot and was smoking (the rubber surrounding the cable was meltating). what does this mean? Also when i crank it, it cranks and then locks for a second (it stops cranking and then starts again). The ecu is good, i just replaced it from a working car. The motor was running perfectly fine in the integra when I pulled it and the civic had a single cam that ran good too. any info would be a great help

melted and smoke sounds like a short somewhere

go-fast_integra

It's the negative battery cable that heated up and melted the plastic that it's wrapped in. If it cranks and then locks and then cranks again, what do you think could cause that?

go-fast_integra

Also, nothing is touching this cable. It just goes to the frame from the battery.

No one has any input or suggestions, please let me know.

Replace the battery ground cable. It's toast.

If it cranks then stops and cranks again it could be timing.Have you adusted the dizzy? I know my sisters d16y7 is real picky it winds and binds.So the question is do it bind or delay when cranking it?Just double check everything really.The ecu, thermostat ground is a bit*h at times.

What did the gsr swap come out of? An 01 teg? 99 civics are obd2b how about the gsr swap?? is the ecu obd2b as well? Theres nothing worse then trying to do good and stupid **** like this happens.Im just trying to help anyway possible.... More info would help as well .

go-fast_integra

ok, i will replace the battery ground cable. I took apart 2 dizzys to make a gsr obd2b dizzy. I think i put everything back on correctly but I'm not 100% sure though. How do you adjust the dizzy? The ecu is a pct (obd2b civic type r ecu) and it's a good one. The thermostat ground is good, I've checked it about 6 times now.

go-fast_integra

The gsr swap came out of a 97 integra gsr. The gsr is an obd2a, ecu obd2b. I used a y8 harness so it has vtec wires and everything plugs in except for 2 sensors ( one on top of the intake manifold and the other is the butterfly valves sensor.) There is a CEL light and its shows 42 i think and thats the 02 sensor which is not plugged in. Nothing else shows, just CEL 42.

go-fast_integra

Also, is that yellow/green wire suppose to be getting volts? (the one that runs from the ecu plug and all the way through the dizzy and plug onto the icm) Let me know cause I'm not getting volts at the yellow/green wire. And if anyone knows the answer to this question, does the dizzy cover that goes on right before the rotor supposed to be on? Because I left it off, it doesn't let me screw the cap that has the plugs running through it onto the dizzy all the way. I don't know if this is what happens when you rebuild the dizzy or what. If anyone has any thoughts I'm willing to hear what you have to say.

maybe you shoulda got a jumper harness and voila? seems kinda weird that it wont goo.

LSBoostedEk

gotta be careful with the OBDII ecu's. i think some if not all of them have some type of immobilizer which will cause it not to start. try to borrow a buddies jumper harness and try an OBDI ECU. Hope that helps man only other thing i can think of

Kapoi83

(the immpbilizer is only on prelude chassis it almost sounds like the starter is grounding out and the engine harness isnt right for the motor should have gotten a jumper harness from obd2a to obd2b then just repinned for gsr swap)

IM DOING A GSR OBD1 SWAP IN MY 97 EK LX I NEED HELP ON THE PLUGS.

go-fast_integra

Maybe I'll get a jumper harness from obd2b to obd2a so I can run the p72 ecu that came with the motor. Does the obd2b pct civic type r ecu have an immobilizer?

5exy_Ek

My LS wouldnt start after i swapped it into my Ek, Starter would crank and occasionally sparks shot from the ground of the battery but didnt start. Turns out i didnt have a ground hooked up. Id check the ground points:
Valve cover to Core support
Trans to Frame
ECU harness to thermostat housing

Just an idea..you probably already have these hooked up though but my car was showing similar symptoms with grounds missing

go-fast_integra

My thermostat ground is good, ive checked that many times. The valve cover ground is on there and Ill double check the tranny ground to the frame but I don't think these are a problem.

5exy_Ek

Yeah i didnt have my trans or ecu ground hooked up (rookie mistake i know) But when i turned the key it shot sparks from my ground cable on the battery and it was warm but it never fried up i guess cause i only tried starting it a time or 2. but once i got them squared away the car started right up

redeg666

do you have the dizzy in backwards

Vindicator9000

JDM ECUs don't have immobilizers. Only the OBD2b US GSR and ITR ECUs have them.

And with that, I'm scratching my head on this one. I know that on the Integra ECUs into a Civic, you have to move the fuel pump pin on the Civic harness, but I don't know about the CTR ECU, and you say you're getting fuel anyway.

I'm still leaning towards some kind of battery ground problem. It sounds like maybe you're not getting enough juice to crank the engine over fast enough to catch.

Have you tried push starting it?

go-fast_integra

I havent tried pushing it to start, I'll give it a try. I can smell the fuel, after cranking it over a couple times, when I'm standing at the front of the car. I also swapped the internals of the dizzy ta make a gsr dizzy obd2b, maybe i went wrong somewhere. But before i did this, i tried the gsr running dizzy with the obd2a plugs (dizzy untampered with) and cut the obd2b harness and wired the obd2b harness wires to the obd2a dizzy plug. There was one wire left over, blue wire, which is for the tach. It still didn't start then, just the same cranking so i doubt its anything to do with the dizzy, maybe the engine harness.

go-fast_integra

oh, and i also took the battery to get fully recharged. So as i'm holding the key the whole time to crank it, it cranks a couple times and locks and cranks a couple times and locks and cranks. Thats all it does.
