i am still trying to figure out my no-start-when-cold situation and have it narrowed down to a few things.
there is a small shop in town that rebuilds injection pumps and i went to talk to the owner and he gave me an idea on how to test the primary pressure on the pump. He said take an extra injector line and injector and put it in place of one of the lines on the pump and see if that extra injector pops when cold cranking. If not, it could be that the primary pressure needs to be turned up.
He suggested 1/2 turn (done by inserting an allen wrench at the fuel inlet of the pump).
has anyone solved a similar problem by doing this? Will this actually turn up the fuel supply to engine or just increase the pressure at the IP inlet?
i have a few other things to check before i try this one but i just want to know what i am doing before i do it.
thanks,
Paul
