So I went to take the SVT out yesterday and it didn't start. As I started to fear I didn't hear the fuel pump prime the fuel system at key on.
Back story, had the same thing happen last fall. No start, didn't hear the fuel pump. So I plugged a spare pump and it ran when the key was turned on. So I knew it was the pump. So around July 4th I finally got to changing the pump out. I used a new Ford updated fuel pump. Got the new pump in and the car ran fine. Well mostly. I did get some hesitation however I put the 1/2 tank of year old gas back in and immediately mixed it with fresh gas. I also ran that tank out and refilled. Seemed ok after that, have 3/4 of a tank at the moment. Ran the car a number of times over 1.5 months before taking a vacation over a week ago.
So the car was parked at least 2 weeks without running. So to troubleshoot I grabbed that same spare pump and plugged it in and it spun up with key on. For the fun of it I grabbed the pump that I took out and plugged it in also, it also spun up with key on. It has been sitting in the basement for 2 months now, wouldn't run when it was in the car.
I put some HEET into the tank this morning but it didn't seem to make a difference. I checked and the fuse is fine and there is 12 volts at the fuel pump plug. The internal ground seems to be fine also.
So what could be the issue? Pump was fine for 1.5 months and then was parked for ~2 weeks. Now it doesn't run. At a complete loss at the moment.
The question is what would cause a fuel pump to not run while in the tank that was previously running fine?
