Have you got the wiring diagrams and ECU pin outs?

As soon as I work out how to do it, I could post them if you need it.

Does the fuel system pressurise and turn off after 5 seconds, if you click switch to ignition, but not to start?

Sometimes a flat battery will make the computer to refuse to operate the injectors.

Check that all of your relays work, sometimes salt water or cleaning stuff gets into them, and they get seized up.

Make sure the computer is getting 12V during crank...The lights on the ECU should remain lit up during cranking.

Chris.

Run diagnostics on your ECU, download the S13 user manual off somethign like Kazaa, thats where i got mine from, it has a MASSIVE section on troubleshooting, very helpful

This weekend I tried to get my CA running and ran into several problems, some stupid and some a little more difficult. I'll admit I lost patience fairly quickly so I haven't carried out much analysis. Anyway the simptons are : Engine is turning over, fuel is getting to the rail, there is no spark, and appears that no fuel is getting into the cylinders either. I'm using a standard computer and loom which is a little rough but should all be there. The computer red and green lights are on. I'm also using the barrel out of the silvia so I know it's not that problem some people have had trying to use the original datto barrel which doesn't allow for the fuel pump. Any ideas would be appreciated!
