i got them all fix now but im still have a problem its harder than ever to statr up. i checked for fuel leaks and there wasnt any. so after 2 days of dealing with hard starts i decided to plug it in all night then it fired up instatly. so found out that it has to be the gp system. so took all of the bullit conectors off the gp and test the volts going to the gp they all had 11.45 volts. the glow plugs still tested good with a test light.so i thinking there geting weak. does all of this info sound right?

Might be that, might be fuel system problems - you bump any return lines while working? How clean were the wires you crimped onto?

You can test how wore a glowplug is by measuring resistance, but you'd have to know the resistance range of a 'good' one too

I think a worn injection pump will be hard to start when cold, and then seals up better when warm. But I'm not sure on that... I know the other symptons/signs but wasn't sure about this one ^
