I have a 91 civic si with a D16y7 that has everything hooked up and is getting fuel but no spark I tried a different Distributor but no luck I need help to get this running bc my 91 4 door blew up . So please help! Thanks

 

you need to specify what parts you used to put an obd2 motor into an obd0 car.

 

actually it was from an obd2 vehicle :p

but yes, op you need to provide what ecu and distributor you're using. i can tell you that either you need to be running an obd0 ecu and dizzy, or obd1 ecu and obd1/2 dizzy. you can't mix and match with obd0 if that's what you have goin on by chance.

 

ya my mistake, i meant obd2

 

I'm running an pm6 ecu with an obdo dizzy, it has the a6 intake mani and I tested to see if there was power going to the dizzy and there is. I went and bought a re manufactured dizzy today as well as new plugs and wire and still nothing :/

 

did you connect all the ground wires???

 

Yeah, I even added one from the starter to the chassis and nothing, even the thermostat ground is hooked up haha

 

main relay??

 

the reason why my old civic wasnt starting was because of 3 things: distributor, ground, main relay. Can you hear the fuel pump prime when you turn it on?

 

if all else fails try a brand new battery!!

 

yeah that's plugged in and in working condition

 

You're sure the timing is on? You're absolutly positive all grounds are hooked up? Have you checked all your fuses?

Also, just to see if the ECU is working, when you turn your key to the on position look at the ECU right when you do that to see if the inspection light blinks really quick. If it doesn't i'd lean towards a faulty ECU and try a different one. BTW, you'll want to find a PG7 with that motor. I'm running a PG7 in my y7 swapped hatch and it runs way better than it did with the PM6.

 

I have every ground hooked up, I didn't look at the inspection light on the ecu though when I first start it up.

 

Try it and see what happens.

 

Ok thanks, I've also heard if the alternator belt isn't on the car wouldn't start, is this true?

 

No your car will still start. Your alternator has nothing do with starting issues. Only charging issues as that's all it's for, charging.

 

??? that belt needs to be on!

 

was this motor running in this car prior to this problem? or is this a brand new swap that just won't fire up?

 

new swap that just won't fire up

 

Check the ECU inspection light....

 

Yeah that seems like an easy way but will that tell me if the ECU is bad right away?

 

If the inspection light doesn't blink then you're not getting power to the ECU for some reason. Have you checked it yet? Maybe just replace it with a known good PM6 or PG7?

 

never knew an obd0 dizzy would bolt to an obd2 head?

 

Yes it will almost everything bolts up. Only thing you have to do to get the motor to sit right is put the motor mount and bracket from the stock motor onto the Y7. And extend two wires, that's it.

Any updates btw?

 

I put the ECU in my friends SI and it fired right up, now I think I am going to have to go searching for a wiring problem aren't I?
