I can crank it but it won't start. I then cycle the key multiple times and then it will start right up. It's showing the fuel icon when it should show the preheat icon on the panel.

I finally went into the fuse box after watching a you tube vid and they said to first check the fuel pump relay before replacing the fuel pump because it could be getting a bad contact or is going bad. It checked and sure enough it wasn't completely inserted. I've not been in there in quite some time so the only thing I could think is that I hit a bump and it popped half out? I pushed it clear in and turned on the ignition and immediately heard the fuel pump kick in! I started it up and it started immediately. No hesitation!

If so I will replace the relay. And go on from there til it's all good.
