Heres the deal. 1992 Canadian CX Taking out my B18C GSR for the winter. Putting in 93 D16Z6. Swapped back in the D16 everything is wired up. Main relay and fuel pump wont kick on. Checked ECU and main relay on my bros B18C swapped car, both work. Put jumper instead of main relay (as per shop manual), fuel pump kicks on.

Not throwing any codes.

This is driving me nuts! Please any input.

Sorry about the title, but I need help fast!

Thanks

 

why are you doing this? seems like its pointless to change engines jus for winter??

are you using the p28 ecu for the z6?

the ECU is USDM obd1 p72 gsr.

 

Check your grounds, check the fusebox (sometimes it shorts when you pull things out of it during a swap and blows main fuses), check the battery voltage.

 

Battery is good, fuses were checked. will check all grounds again.

 

even tho a ground is connected, they mess up. one day my tranny ground went on me and car didnt start

 

grounds triple checked. replaced and added an extra.

 

The issue is fuel.
We tested the main relay, the computer and the fuel pump all seperatly and they all work.
When you turn the key on though with everything hooked up the fuel pump is not priming so were a little stumped.

TTT in an attmept to get my brother to work in his OWN car for wednesday.

 

hrm...i had the same problem. did you have to wire up anything to the ECU? check all your connections. also, check the ACG fuse under your dash. it should be under yellow top covering it or be right next to it.

ALSO check your fuse under your hood. it's the ECU fuse.

 

i know whats wro-ong :whiny baby tone: lol pm me.

 

Fuses checked AGAIN...and nothing has been changed running into the ECU.

appears to be some sort of wiring flaw within the harness i assume.

I unplugged the engine harness checked plugs to make sure nothing was broken or loose. plugged it back in hooked up the battery and the pump kicked on.
so far so good for now.

check the harness, make sure none of the pins were pulled out while doing the swap
