I got this 1991 240SX that the P.O started an Stock KA24E SOHC Swap. He tore the dash apart, and the engine bay is a mess.

I am missing most of the EVAP system, EGR and who know what else.

I would love to have Wiring diagrams, Vacuum diagrams, pictures of the stock engine bay.

I have no inspections here. So removing these systems is fine with me.

Gwad and idiot, this previous owner is, what the hell did I get my self into.

I manged to get the wiring hooked up, so I have power to the cab and the engine. but it's a mess.

So fuel Check, Spark Check, Starter Check. It didn't fire up, tomorrow I am going to check the ECU, and that the injectors are working. I will take pictures.

You could try looking at the factory service manual as a reference.

Thank you for the reply, and being civil. I wish I could rewrite the first reply, to make more sense. I am trying to hunt down a hard copy of the service manual.

I have one problem, I am only getting 8-9V at the fuel injectors. I will pick up a noid (SP?) light when I can.

Might you have a suggestion, on the best place to test and check? Why it only getting 8-9v, the battery is new and fully charged.

I believe now the stock engine was a DOHC, not the SOHC it's got. I am going to do more digging, to find out.

The ECU has power, injectors are working.

Ok, all three VIN match and they all say that it came with a SOHC engine. The ECU matches. So I am good there. No clue why he gave me a DOHC head with cams, and said it was from his blown engine.
