i just did my mpfi swap on my 89 dx

matched up the colors at the dizzy, blue green to C1 and blue yellow to C2, original pin from C1 moved to B10, original pin from C2 moved to B12.
injectors are from d16y8
injector 3 to a5, injector 4 to a6. blk/yel wires soldered together, and to one of the blk/yel from old dpfi injector
injector 1 is dpfi yellow wire. injector 2 is dpfi red wire. blk/yel from inj 1 and 2 soldered together with other wire from dpfi injectors.
removed original wire from a3 and capped. removed original wires from a5 and a6, put a5 into a3, capped a6.
should i have soldered ALL the blk/yel wires together?

using d16y8 intake manifold, b18b tb
while running, it bogs out a bit.
sorta like rrrRRR rrrRRR rrrRRR __ rrrRRR rrrRRR rrrRRR __ ... etc
i hear a dripping after i shut off the car, from the back of the block, a pinging drip noise
profuse smoking, car didn't do that before
and a really scary clunking noise when i shut it off, from the drivers side
seems like the motor wants to spin for a few more revolutions than it should when the ignition is turned off
don't have throttle cable hooked up yet, but that shouldn't cause this issue should it?
i haven't moved the car since starting this swap, and have decided not to drive it till i figure this out

any help is appreciated

 

i checked the spark plugs. they are pretty black. cyl 4 plug had some oil deposits on it, plug was pretty loose. if i pull the spark plug wire off cyl 3 while it is running, it doesn't surge. sounds like misfiring, what might cause this?

 

well if it was loose I would check that to make sure they are all tight. Do that first. By the sound of it I would also change the plugs but lets tighten them down first.

 

they're all tight now, cleaned the gunk off of them. didn't help a whole lot.

 

My Bro did an MPFI swap in his 91 EF hatch. He swapped out his main relay. Come to find out the one he put in there was garbage. We switched the main relay back, and it reved out nicely, and ran like a raped ape.

I would also double check all wiring and connections to make sure everything is hooked up right, you would be surprised what you miss when you are tired, and or frustrated after working at something all day long.....lol believe me I know!

Oh yeah, I'm dropping a Y8 in my 93 EG as we speak. I will probably have it finished up tomorrow

 

yeah, I'm going to actually solder all my blk/yel wires together today, see if that helps. it could be that crappy old dizzy causing the odd firing...
the d15b2 is old, stuff is probably worn out. going to drop in the y8 today.

 

Dripping? Smoking? RRrrrr?

You did something wrong. Check every single thing that you did and make sure it is correct. Solder and heat shrink your wires. Do you have any CELs? What ECU are you using?

 

i got lost reading after injectors are from d16y8. i dont know where you got A5 and A6 from

in the instructions here> http://www.angelfire.com/d20/hcivic88/dx-siwiring.html

DPFI 1 is yellow and DPFI 2 is red. DPFI 1 goes to injector #1 (brown) on the mpfi manifold. (counting from dizzy) and DPFI 2 goes to injector #3 (blue). injector #2 goes to A3 and injector #4 goes to A7.

the 2 black/yellow wires from the DPFI injectors goes together and solder them both to all 4 red/black resister wires from the injectors. (doesnt need resister box)

thats your injector wiring.

Cut c1 and c2. from the ecu plugs, run them into the bay. from the cabin harness, run c1 to b10 and run c2 to b12.

in the bay, run c1 to dizzy blue/green. c2 to blue/yellow.

i didnt see you mentioned about TPS, switch both yellow and green wires around.

i followed that posted site for my recent dpfi to mpfi swap and it fired up the 1st try with no codes. remember dont loom the harness until you are satisfied with the outcome. once everything is said and done, then loom the harness.

there are 3 plugs left over.

 

will the pm6 fire those injectors if so i have a set id like to try, im already using obd I z6 injectors without a resistor box

 

the si ecu will fire then as long as they are wired correctly.

 

well mines done correctly it was easy i built the harness in 2 days in my living room...used my std harness (dx i guess), not to hard at all just remeber that 2 injector grounds are existing the only 2 you need run to pins A3 and 7 i believe id have to go check, im curious though will my obd I plugs work or do i need to match the injector plugs they appear different

 

yes obd1 plugs for the obd1 injectors, obd0 injectors and obd0 plugs..

i built my harness in about 30 mins.

 

That should make a little more sense as to what I did, ha ha. I'll go fix my mistakes and be back!
The thing that scares me the most is the horrid clunk from (I think) cyl 1 or 2. Crank keeps trying to rotate when I turn the car off. Could be my injector wiring? Gonna have fun troubleshooting today... ha ha...

Thanks for the help guys. I'll be back!

 

no no, you fool lol, i get what your trying to tell me, im not the noob here i just didnt know what the resistance was across those particular injectors, since there y8 injectors ill need obd II plugs, not a problem, and difference in flow over the obd I z6?
and the harness took me a little longer because i wanted to make sure it was all right, plus i soldered and heat shrinked tubed everything before it went back into the car, OP make sure you do this wire splices and black tape arent gonna cut it here

 

canadian ef: i think you are adding too much work switching a lot of wires around. i think you should put all the wires back in their original spot and redo this madness. the site i provided is very straight forward.

singlecam: im not calling anyone a noob. im trying to help from the best of my knowledge. obd2 clips/obd2 injectors i do not know the flow difference from obd2 from obd1 injectors..i would think they are better than the old obd0 right? haha.

 

Well I switched the wires around to the correct spots... Verified it, same issue still persists. Soldering + heatshrink as I go. Did I wire my dizzy wrong???
All I did was match up the colors since they had the same scheme anyways...
If my dizzy is bad (which is possible), can I use an OBD1 dizzy in its place, with an OBD0 ecu if I re-pin it to accept the plug? just trying to rule things out here.

I have a CEL, but the LED on the ECU isn't lighting up at all, no flicker, nothing. Not with the car on, not with it off. =(
It ran for a little bit, CEL came up, turned her off. Saw the smoke slowly wafting out of the exhaust...
