When I did the test to insure power was going to the the fuel meter and I got 4 strobing and 2 solid light but strobe when you turn the motor over. Having a fuel issue tested the injector power.

The crank sensor is good. Could it be the fuel pressure regulator. I have not removed and inspected the spider injection.

You should check to make sure you are getting the correct pressure and it could be a bad regulator or the spider.
