Hi,

How much fuse did you put in it? In other words, did you fill the tank or just add? I ask because often people overfill the fuel tank, and it causes fuel to be drawn in by the evaporative emissions system. When that happens, it can cause this.

When it does start, do you notice any gray smoke or anything from the exhaust? Are there any strong odors?

Let me know.

Hi,

I didn't realize it was only after adding fuel. I thought the problem started after you added fuel and has been consistent since. That was my mistake, sorry. I want you to try something. The next time you add fuel, do this to see if it changes anything.

1) Turn the ignition key from off to the run position (engine off) and count to 5.

2) Turn the key off and repeat step 1 a total of five times.

3) On the 6th cycle, see if it starts normally.

Let me know what you find.
