heater plugs,? I changed 4,3,and 2 with no problems, but to get number 1 out I had to take the fuel pipe from the injector pump, after changing the heater plug I put the fuel pipe back on and used the hand pump to put fuel back into the pipe, now I'm having to turn the engine almost to flattening the battery, before it starts. should I have bled the injectors after having the fuel pipe off. ( there are no air bubbles in the clear fuel pipe I took off.)
