Good morning,

Did you check the pressure on the spider from the fuel pump?

Fuel Pressure (Key "on", Engine "off") .................... 379-427 kPa (55-62 psi)

You can rent a tester to verify this pressure.

Check the electrical connector at the spider for any damaged or bent pins preventing the operation of the spider.

Let me know the results when you can so we can continue if it still does not run.
