ok i have a 91 crx that i swapped a sohc zc into. i sent the engine harness into Hasport and had them to that harness as i saved the dash harness for myself. im running a pm6 ecu and obd1 injectors with no resister box. so ive got the motor in and everything wired in right. (i checked everything like 8174 times) though, upon attemping to start the car i realized that it doesnt want to idle by itself and it pops and stutters like crazy! even when i put my foot on the gas it just barely raises rpm very slowly. anytime i try to come off the clutch it just stalls. it throws a code 7 and sometimes a code 16. i just put a new dizzy cap and rotor button on it today and it helped a little with the popping but still everything else remains. its getting on my last nerves. any help would be great!

 

anyone?

 

for the code 7 u prolly forgot to switch the tps wires, and for the code 16 im not sure, i know u did the obd1 thing so u dont use the injector resistor box, maybe has something to do with this? because code 16 is for defective injection system

 

It sounds like your injectors might not be wired correctly. The only way I know that you can use OBD1 injectors with your PM6 ecu is by soldering the 5 wires going to the resistor box together. I don't know if you already did this but this is how it should look:

Wiring for OBD-0 Injectors


Wiring for OBD-1 Injectors

 

did you check the timing?

 

timing is spot on. the engine harness was done by Hasport so its all taped up already and im not sure how they wired eveything. but the plug that would have a resistor box in it has a blank plug plugged in. ima try to solder all the resistor box wires together and see what happens. and as for the tps, i've swapped wires like 8 times and it doesnt make a difference.

 

Don't forget TPS and IACV plugs are exactly the same, I've seen a lot of people plug them in backwards...

 

well i played around with the plug wires and got the car to idle. it idles like crap though. i started pullin plug wires to see if that had anything to do with it and shortly after realized that if i pulled the number 1 and 4 wires the idle didnt change. more to fix! so now i have to find out why im not firing on 1 and 4. hopefully the fuel soaked plugs have something to do with it. ima check the injectors for power and replace the plugs and see what happens. fingers crossed.

Iacv and TPS aren't the same plugs you may be reffering to the map and tps cause they both do have 3 wires. Just a quick update.

if you did an obd1 convertion you should be using an obd1 ecu like a p06..i hade da same problem when i was doing my obd0 to obd1 jumpers n was using a pm6 which is an obd0 ecu wit and ob1 diz n injectors n was doing wut urs is doing...try getting a p06 ecu n u should b fine...obd0 ecu need obd0 diz..obd1 ecu need obd1 dizz...good luck man

 

no just the injectors and injector plugs are swapped to obd1. but anyways i changed the spark plugs and messed with the dizzy for a minute and got it to fire on all cylinders. i actually just got in from driving it around the block and back. (with was quite fun being as its 8:30pm and i have just headers and downpipe...no exhaust.) but now its throwing a crank angle sensor, TDC sensor, and still the TPS sensor codes. it doesnt want to climb RPMs as fast as it should. im assuming the codes cause that. so ima change dizzy and try it again.

 

ahh! but may i inquire an answer?! the dizzy that i have on the rexy right now is an obd1 dizzy with two plugs coming off of it. and i think its for a z6. i found one in my garage that looks the exact same except all 9 wires are integrated into one plug. i read im supposed to have a d16a6 dizzy?. is there a difference internally? or is my the current one right? the one i found has the same part number as the si dizzy for a d16z6 we have in stock at my work. except it has only one plug. anyways, i changed the ignition control module ( CKP/TDC sensors) in the cuurent dizzy and it ran a little better. i dont have a TDC code anymore but i still have the crank angle and TPS codes. the car still runs in limp mode. if its got a brand new ICM in it why would it still throw the crank angle code and run in limp mode? that SHOULD be the last of my issues before she comes alive. any thoughts?

If you are going to use the OBD1 dizzy make sure it is wired right. This is something I found while searching around:

 

DID U TRY RUNNING IT OPEN HEADERS?....I THINK UR CAT MIGHT BE CLOGGED...IT TENDS TO THAT WEN THE CAR SITS FOR A WHILE

 

okay so i wired in an obd1 si dizzy and plugged up an obd0 to obd1 jumper, partnered with a p28 ecu and she ran! revs all the way to redline. i get vtec solenoid and vtec lift valve codes but its a non-vtec so its fine i guess. also an o2 code but i dont have one plugged up yet. she does have a lot lag before 3000rpms but once it hits 3 it pulls! i still have a lot more tuning left but ill keep updated. thanks for the help guys.

 

alright so this throttle issue is really pissin me off. it bogs everytime i floor it but if i just barely tap the gas its revs normal. i can be at 2k rpms cruisin and pound the throttle and boggs to like 1k and the slowly pics up speed. and thoughts?! please!

 

i didnt read all the post sorry, but have you done a complete tune up? oil ,plugs, cap ect... also check your injectors see if there working correctly

 

yea ive replaced the dizzy cap, rotor button, plugs, wires, fuel pump(wisco fuel cell and MSD external pump), and i just replaced the fuel filter. the new fuel filter helped it alot but it still has a slight throttle lag issue.

 

if u went obd1 shouldnt ur dizzy be obd1 and have a 4wire o2 sensor?

 

i once had the same problem. the fuel line was leaking at the rail because one of the washers fell out. you could hardly tell it was leaking but it was. check and see if your leaking

 

check the voltage on the tps.

 

no its not leaking and yes it is an obd1 dizzy. i did get rid of the throttle lag by retarding the cam gear. i went tooth by tooth until it got better. i ended at three teeth. no more throttle lag but it threw the car into limp mode. she revs up perfect, just ends at 3200 rpms. anything?

Wait, did you move the cam gear on the timing belt?!? Or do you have an adjustable cam gear?

 

i moved just the cam gear and cam alone.

 

ok so i just swapped the ecu out with an obd1 pr4 out of my integra. (i heard that it will run the sohc non-vtec zc motor.) it got rid of all the codes, except the o2 code cuz im to lazy to hook one up right now, but now she doesnt want to start at all. she cranks and turns over just wont catch! im about ready to just sell the freakin thing!
