Fuel pump? Help.
Okay, so I've been going through it trying to figure out the problem with my 8. I've changed my spark plugs, then wires, then coils. In that process maybe trying to get it to turn over while it was running bad I think something else may have went bad, I was thinking starter, because I've always had a slow start. And I know the unupgraded starters from 04-05, so I ordered a starter but now since it does turn over, so I'm thinking making fuel pump. Is it possible for a bad fuel pump to cause the car to crank and crank and crank and throw a blinking CEL before the car is even started? With the key just in the on position. Been trying to figure this out a while now. Something went bad in the process of fixing a problem which is why its been so hard for me to pinpoint the problem.

The fuel pump usually doesn't cause a problem unless the pump itself overheats. It usually only over heats when the engine is sucking down lots of fuel, and this doesn't occur at startup.
Check the engine block ground, validate that your ignition is hooked up securely and correctly. Pull the plugs and crank it to see if there is fuel in the chamber, you might just be flooded.

You said pull the plugs and crank it. It didn't make sense to me lol so I was a little confused, so crank it without the plugs? It wont turn over or nothing but will empty the fuel? Is that right?

Jay, I recommend starting with the basics. Confirm that you have spark with a coil tester. Confirm that you have fuel by cranking and pulling the plugs to see if they are wet with fuel.
If you have no spark but good fuel, check the grounding connections, replace ignition if needed.
If you have no fuel but good spark, then you have a fuel pump problem.
If you are missing both, then you have an e-shaft sensor problem.
If you have both, you are flooded, too slow starter speed (due to battery or starter), or failing compression.
Find out what you HAVE first.
