The car is hard to start after a cold soak. It takes 4 - 6 tries to get it started. Fuel pump and filter have been replaced, due to filter leaking, and low pressure from the pump. It is acting like the pump has lost its prime, I replaced the pump again. It still has the same issue. I used a Delphi pump both times.
Under normal driving the car runs/drives fine, until quick acceleration is needed. It then hesitates and feels about half power.
I tested the TPS and found a dead spot in it almost at WOT. I replaced it and it did not help the problem.
It has the following codes set:
P0128
P0135
P0401 (recurring after clearing codes)
P0131
Your help is greatly appriciated.
