How do you test these things ? I was told to pull my CAS and spin it with the coil pack out it should spark well if I did it right it did'nt work so I need some help on figuring this out . Thanks ps my car wont start but cranks good and has fuel.

Are the 2 green relays in? they are near the ecu. Or if someone did the conversion for you the coil packs and injectors might not be getting any power.

How do you have your fuel lines hooked up?

The injectors click when you spin the cas, put make sure you pull the fuel pump fuse so you dont dump fuel into the motor.

Another good idea, if the lines are reversed it really won't fire over.

I swapped fuel lines and there was no change Im pretty sure its not getting spark

Did you open up the harness and trace the wires to see where it's getting power from or if the ground is grounded? Don't wait for someone to give you the answers you have to trouble shoot the problem or take it to a shop and pay them to figure it out.

I was wondering how to test these parts? and some advice I didn't know if it was a common thing or not.

I would start by trying to find a how too for the RB20DET wiring swap, then google the problem your having.

Search the Nicoclub RB section. You will prob find what your looking for there.

Did you do the wiring your self? If you tell me what wires were connected to where, I can compare it to my running swap.

I found two green relays that are located on the passanger side between the strut tower and the firewall well they look really coroaded and probably are junk plus the plugs the plug into what are these for ? could this be my problem ? can I directly wire this and by pass the relay?

What color are the wires that go into the relays? orange? white? white/purple? What are their pinouts in the ecu? they could be your problem.

and one of them are blue other one is green I think I need a new engine harness mine doesnt look to hot by the fuses its a mess of wires and offthe ecu plug there are some wires tied in dont know why and on the side right above the ecu there are some wires with grey dots that are completly cut off I dont know that much about wiring on a car so its a little harder to figure out whats wrong.. I bought this with these problems btw
