I tried hooking up my multimeter, black wire to the battery, red to the relay, and really didn't see any numbers come up. I tried DC amps at first, then
dc v, then ohm. Pretty much flat lined.

I must have done something wrong, because before I changed the glow plugs, the car would at least start. According to one member, if all the glow plugs are out, the car is near impossible to start. Being that it could start, though a bit rough, he reasoned that at least a few of the plugs were glowing, even though the light on the dash wasn't coming on.

But now that I changed the plugs, the car is reluctant to start. It cranks, but that's about it.

What now?
