Ok I got the motor into my car and everything all bolted up...got a new AEM fuel rail into it and then tried to fire it up. No luck...it's turning, but it won't stay on...the injectors were my first thought so I swapped out the injectors, so I'm not quite sur ewhat is wrong w/ my car...it hasn't been running in over a year so I'm not too sure about the condition of the gasoline, but I added new gas, new coolant, new oil...every fluid imaginable. I need to get this car up and running. Then I started to think that maybe it was the distributor. Which distributor am I supposed to use on this swap? The stock one or the Z6? Any help would be greatly appreciated...thx a lot. Could a vaccuum leak be part of the problem? I think I "forgot" to attach that one bolt that's like right in the middle of the intake manifold on the bottom...jes cuz I didn't think it would make a diff. I can get the CRX to run w/ some ethanol into the throttle body, but the second that I take it away it dies. Any thoughts? Thx again for any help.

 

what kind of ecu are you using?
the 91 CRX one? r the z6s?

 

need to know more info what ecu also have you checked all your grounds it could have been missed in all the impatien-ness of getting your car done

 

'91 ECU, the car shop ordered me a P28 ECU and then I was like how much was that and they told me $190, and I was like no...you can use the stock ECU no doubt. So they were like ok...

 

Grounds...yup they are all good, but I'll double check tommorow... Using the stock ECU from a '91 Si.

 

with the A6 ecu you need to use the A6 dist and A6 injectors
a friend of mine put a Z6 in his HF using the Z6 dist and HF ecu. It ran like ***, he pulled 1 or 2 of the sparkplug wires and the motor ran better than with them all connected lol

 

The injectors make a diff? I pulled the injectors off a B16 engine at the shop. and they fit just fine. The A6 distributor won't bolt up to all the points on the CRX will it? Only like 1 or 2 bolts right?

 

I'm thinking about doing that swap pretty soon.... Let me know how it goes... what sites did you use for the swap info??

 

OK so your using the PM6 ECU? Then you should be running a injector resistor box with obd-0 injectors. And also you should be using the D16A6 distributor the only way you can run the Z6 dist. is if you convert your car to obd-1. Oh and your going to have to do some fabricating to get the A6 dist. to mount onto the Z6. And yes only 2 or so of the bolts will be holding it.
