Sputtering on incline

[sculptor310]

So I've had a host of problems with my Whipped '15 since moving from Denver to San Diego. The most current symptom is sputtering after being parked facing uphill for more than a few hours.

The car moves forward, but barely. After a few seconds, it starts to move normally.

Any suggestions?

Thanks!!

Could this be something tune related? You moved from Colorado which is a really high elevation to San Diego which you're basically at sea level. Fuel enrichment may need to be adjusted by your tuner.

Just sounds like the fuel drains out of the rails back to the tank. Try just pressing the Start/Stop button without clutch/brake depressed to prime the rails, then fire it up.

If you have an aftermarket fuel hat they are terrible with surge. If its happening when fuel levels are 1/4 or less then likely pump intake is getting uncovered

The fuel pump is stock.
