The cold start valve may not be working as it should. The cold start valve supplies a rich mixture of fuel when the engine is cold. If it is not working you will experience hard starting. It can also be a partially clogged fuel filter or a failing fuel pump. First thing to do is replace the fuel filter. If the symptoms persist then have a fuel pressure test run to rule out a weak fuel pump. If the pump is good then check the cold start valver wiring. Check the valve for leaking. The solenoid may be defective or the O rings need replacing.
