View Full Version : I want to bold everything on my ECU pinout that I need for my car to start.

Not necessarily run good, but just to start. It's an RB20DET going into a s13. Yes I followed the "Wiring for Dummies" tutorial, but I'm still having a few issues.

Here's my graphic I made:

It's in Excel, and I just want to bold every pin I need to check to make sure the ECU has everything it needs to ground the injectors/coil packs.

I know it needs the crank angle sensor (CAS), 0 degree and 120 degree?.. And I guess there's also a cam shaft position sensor? (I don't even know if there's a difference between angle sensor and shaft sensor)...

The thing you can take off and spin in your hand to make the coils spark is labelled as the crank angle sensor in the FSM.

I plan on checking everything tonight, and I understand I need fuel, spark, timing, and compression to get it to start... But in order to get fuel/spark, I know the ECU needs to know the position of the crank/cams so that it knows when to ground the injectors/coils to spray and spark the gas.. Anything else I should be checking? Is there an easy way to test the ignitor chip? etc... I've been reading for days on here, but these are a few questions I have that haven't been able to find a definite answer for..
