In my efforts to solve a no start/stalling problem over the past month I have done the following:
Replaced accordion hose
Replace vacuum brake hose and installed new booster check valve
Installed new power stage, fuel pressure regulator, intake manifold gasket and crank position sensor
Cleaned idle air control valve
Checked OBD with an “all clear” result.
I have thoroughly checked and rechecked for vacuum leaks and have found none.
Other than the throttle body, what else could be the cause? The car runs better, but it frequently needs to crank a lot with some pumping on the gas pedal to get started. Especially when warm.
Thanks for your input.
