Sounds like you may have a problem with fuel loss from one of the following

1) Fuel distributor leaking fuel down into the intake causing un metered fuel to be dumped into the engine causing a hard start.

2) Fuel pump check valve at the fuel pump leaking pressure back to fuel tank.

3) Fuel pressure accumulator not holding pressure.

4) EHA not enriching the fuel mixture like it should at first crank.

5) Coolant temp sensor may be bad.

6) Low compression in the engine.



Hope this helps
