Thanks for all the help guys. I took all the glow plugs out except the one closest to the fire wall (can't figure out how to get to it) and hooked them directly to 12 volts and grounded them. None of them glowed. I Installed new glow plugs. Now the glow plug indicater lights up, stays lit for about 2 seconds, I turn the key and it starts right up. I'm a happy camper. Any ideas on how to get that one closest to the fire wall. I used a swival and a ratchet on the rest which worked great. But that one has the oil filter right in front of it.
