Initial findings and hope for a cure of orange ignition spark

What components other than the coil do I need to look at to strive for a blue white spark?

I put the towbar on the car today and towed it home.

I verified that the main pump was running but when I put a pressure gauge on the fuel rail it registered zero. Tried to run fuel into a container from the open fuel line and got nothing.

When I listened at the filler neck when someone tried to start the car I could hear the intank pump running. What was more interesting was that I could hear gasoline draining back into the tank as though it was being poured out of a container!

The only thing I could think of was a failed connector hose on the fuel pickup. I added five gallons of gasoline and with the hose at the fuel rail disconnected into a container I cranked the car and eventually fuel showed up. I replace the fuel line to the rail and after a few more cranks it shows 40psi on the pressure gauge and the car started.

It ran for about 15 seconds but when I tried to let it idle it died and would not restart. I checked for spark at the coil. The coil will jump an orange spark about ¼” to ground. I removed the sparkplugs and they were all fuel soaked but would also only deliver an orange spark.

I ran a quick compression test and got 90 psi on each cylinder. This is way down from the last test and I think part of the problem is perhaps the excess fuel washed the oil off of the cylinder walls. This is the point where I ran out of light.

Tomorrow I will squirt oil into the cylinders before replacing the plugs and trying to start the car again.
