Hi all. When I am on an incline and stopped at idle, my car's idle will drop, and sometimes it'll stall on its own. When this happens, or when I stall it trying to hill start, the car is unable to start again. It cranks, but doesn't start up. When I push it back onto flat ground, it'll start up just fine again.
I'm pretty sure it's an issue with the fuel system (low fuel pressure?), but I am unable to narrow down the problem any more than that. Has anyone also had this issue, or does anyone have any suggestions? I'm definitely going to replace the fuel pump.
The car is a 1994 del Sol with a B18C1 swap and mid engine conversion. The stock fuel tank is in the front under the hood.

 

You might want to crack open your fuel pump cover on the gas tank. I suspect there is something wrong with the sock on the fuel pump.

 

Thank you, I will take a look at the fuel pump. I will conduct a fuel pressure test first, on flat ground and at an incline just to make sure it IS a fuel pressure related issue. Too bad the fuel rail doesn't have a Schrader valve.. I'll have to cut the hose to fit an adapter

 

Fuel pump.

 

Fuel pressure test is done at the filter in the engine bay. No hose cutting required.
