K so i have swapped a y7 in my 88 hf. I have gotten a p06 harness and ecu and just got another single cam obdo dizzy. Its my second dizzy and still no spark. I just changed my main relay, and went over all the grounds and looked pretty closely at the harness and all looks good. Im getting four cells 6,10,15,20. But no spark i have been messin with it for a bit now and cant get it so fire up any one have some ideas??? My 6,10 i can take care of i know whats up with those cells

 

Any body i am out of idea's??

 

any body

 

are all your grounds good? to check for power going to the coil unplug the 2 wire conector at the dizzy. then get a test light and test for power coming out of the engine harness on the thick wire. have some one turn the key to on and you should get power. if you dont its probably your ignition switch if you do its probably your coil. also make sure you screwed in the thick wire on the engine harness to the under hood fuse box.

 

All of my grounds are good. I just got another dizzy that i know works. I did a ohms test with the key on and the cap off and i was getting the right amount of power to the coil and out of the coil. I just changed my main relay also.

 

Would my ignition switch be out if i could still turn it over??

 

i'm confused. you have a p06 and a harness seperate, or you have an obd1 harness? assuming you just left out the comma then what you're saying is you have an obd1 ecu and an obd0 distributor. that won't work. you need an obd1 dizzy.

 

if your getting power to the coil then its no the ignition switch. the reason an ignition switch can still go bad even though you can turn it over is when you turn it all the way it could work but when it springs back to the run possition that conection inside the switch can be bad and visa versa. ive been through a ton of hondas and for me that is a common problem on ef's. i always grab ignition switches at picknpull. and d16si is right you cant run a obd1 ecu with a obd0 dizzy.

 

K so would that why im not getting spark be cause the dizzy is wrong??

 

affirmative

 

so bein kinda new to this stuff is obdo and obd1 a difference in the plugs or what is the difference

 

yes the plugs are different, but the reason why it wont run is internally they are different. the reluctor wheels inside them send out different pulses and only the matching obd# ecu can interpret them properly. so an obd1 ecu can't interpret an obd0 dizzy signal, and vice versa.

 

Alright so maybe i got my stuff mixed up because all my stuff plugged right in. The ecu plugged right in to the harness and the harness plugged right in to the dizzy.

 

you're using a p06 ecu? obd1 ecu's won't plug directly into your cabin harness unless you either cut off the obd0 plugs and wired on obd1 plugs, or you purchased an obd0 to obd1 ecu jumper harness. either way, if you're using an obd1 ecu and obd0 dizzy, the car will NOT run.

 

alright i didnt cut any thing but i will go over everything tonight and check it over again

 

K so my bad on the po6 its a pm6 harness and ecu. Right at first now i turn my key on and i get a little spark but nothing when i turn it over and i dont get that little spark again. Till like that next day then i get that little spark but nothing. I double checked all my grounds all my connections and everything looks good my sensor on my thermastat housing is unpluged. But other then that everything is hooked up. So i have know idea what it could be. Like i said this is my second dizzy that is known to work and second main relay and ecu is good. I get a 6,15,20 cell code so any ideas of whay i could try to get this thing to start??

 

was the car mpfi to begin with? didn't occur to me before but it seems odd that you'd mention that you're using a pm6 mpfi harness. leads me to believe maybe the car you put this harness into was not mpfi to begin with

 

k now im not sure if it was, the guy i bought it from was just getting ready to throw a gsr in it. But for some reason didnt i think his wife didnt want him to have it any more, so i got the shell really cheap. So i figured it would be fine to throw a single in it im not sure about the mpfi. But my luck its not so what does that mean? How do i fix this?

 

This is my first actual swap iv had cars with swaps in them and done bolt ons but nothing from start like this.

 

ok i just realized you mentioned at the top that your car was an hf. if that's the case then you need an hf harness. the si and hf harnesses are different even though they are both mpfi.

 

Alright the guy i bought the harness from gave me a intake manifold that was for the harness and told me i needed to use this so should i switch manifold back? By chance do you know what exact harness i would need would i need to switch ecus? Do you think if i do this my **** will start? by the way thanks for all your help.

 

you need an hf harness. dunno why'd he say you need to use the intake manifold he gave you.. the one already on the y7 will work fine, assuming it came from a manual trans car and has the regular 2 wire iacv on it. you can still use the pm6, it will run the y7 no problem.

not a problem. thats what we're here for right lol

 

I just found a hf harness in the next city over ima try to pick it up tommrow or the next day so i will let you know how it works out.

 

So really quick ? i need a pm8 harness right that is what i can find that is a crx 88-91 hf harness and ecu but my pm6 ecu should be fine to use i just need to get a pm8 harness? right

 

affirmative
