I have a 1990 JDM TT swap. I just recently finished my turbo upgrade. I went to start it and it cranks, but won't start.

I have fuel pressure. I pulled the spark plugs out and have no spark anywhere.

I replaced the PTU with the 2nd gen PTU last summer. I was going to check and see if I was getting a signal from the PTU with a test light tomorrow. Will also be checking for codes tomorrow.

How do you test the CAS? I've read this can cause the same problem.

Any other things anyone can think of?

The car did run before I parked it.

Any help will be greatly appreciated.

 

Well I figured it out. The CAS connector had some corrosion on it. Cleaned it off and bent the terminals in the connector. It fired right up.

Now I have an injector problem. Cylinder #6 fuel injector isn't firing. Thinking I'm going to upgrade them and my fuel pump and turn up the boost.

Correct me if I'm wrong on this. When I tested the injector I have power and ground, but no pulse through either side. I was using a digital multimeter so it might not have been quick enough to catch the pulse. Going to get a test light and check again. Hoping I don't have an ECU problem. Just replaced that when I did my swap. Would rather be an injector.
