I been working on my 1.5JZ swap the last 2 days. Got the motor in, everything plugged in. Car initially turns over but no spark. I noticed on the body plugs that theres a few wires disconnected(4 or 5 wires) so I called my buddy who gave me the engine set if that was intentional. He answered YES, it was for the tach, speedo etc.

So I had a guy come over that has some experience with 1J's and he told me that those wires are supposed to be connected. He connected 2 wires and the car turns over and fires up but has a big miss then dies, sounds like its running on 3 cylinders.

We tried swapping out igniters, that wasnt the problem. He told me it sounded like a wire issue.

Is there suppose to be any disconnected wires at the body plug? If yes, which wires?

Theres also a plug next to the igniter that I have disconnected, where does it go?

 

a really small white thing



It is called a condenser.

 

Whats that for? Can I jump the plug?

 

It's a capacitor 90980-04083. What does it do? idk but I would assume something with timing.

Your stock one should work if you have it . Of course you could always get it on ebay or one of the wreckers in the for sale section.

 

That's the noise filter it usually goes right next to the ignitor on the gte cars.
That will not stop the engine from running.
