Check and replace the water temperature sensor. Your engine is staying in cold start mode because the sensor is faulty and not sending pulse to computer for it to take it out of cold start mode. The engine is constantly flooding. Like keeping the choke on with the early carbureted vehicles.

I can only relate this problem to those similar to Ford F150's,,,on the fords it would be bad grounds from the battery to the frame,and engine,,and from the engine to the Firewall.
This would play havoc with the ECM especially when it was damp.
So i can only suggest the obvious to me at least.
Good luck to you.

You said you have fuel flowing from the inlet line of the injection pump? But not at the injector lines?

Start with the plug wires.You may need new plugs but my experiance is that the plug wires are the first to go.

HI! The other thing that controls the fuel is the PCM (powertrain control module). The PCM is like the car's brain that when it fails everything else's fail. The PCM has connectivity on all electrical current that runs inside the car including the engine and transmission. Hope this helps and thank you for using FixYa!
Basically this means that an oxygen sensor in bank 1 detected a lean condition (too much oxygen in the exhaust). On V6/V8/V10 engines, Bank 1 is the side of the engine that has cylinder #1. Try cleaning your MAF sensor (Mass Air Flow) and run a good fuel system cleaner through it.
