I have a 92 truck automatic transmission bought the truck from wifes grandpa, Wife wanted it sentimental thing, needed a truck to leave at the lake to put boats in. Truck had been sitting for about 3 years water pump was leaking. Changed water pump, Starter, Batteries and I drained one of the tanks put clean fuel in, installed a temp electric fuel pump to purge fuel line cranked on truck with glow plugs out to clear fuel out changed fuel filter. Long story short, new injector pump, return line kit, Injectors, Glow plugs. The connector on the fender with the glow plug wires (yellow) was smoking so I bypassed the connector. Truck starts and runs fine but the Glow plugs are kicking my butt. The truck will only start if take the wires to the glow plugs and touch them to the yellow lug on the relay for about 10 seconds then it starts and dies and eventually starts after a couple of times and runs fine. Relay was bad changed relay and now it just clicks and clicks, everything I read said relay is bad, so I purchased the whole controller with relay still clicks. Glow plugs that came with kit were diesel Rx plugs that ohm at .7 all of them, I have power to all glow plugs, pulled them again and rechecked ohms on them. I rechecked ground and it is good.Sorry about the length but sometimes all information is good.
Questions
What is considered good ohms on glow plugs there is so many posts but they don't talk about .7 they only talk about .3 or .4.
After reading tons more posts about the clicking and seems that the clicking is either a bad relay but couldn't it be the controller sensing too much resistance? and if so what next...
The only thing left is to build or buy and new glow plug harness( started pulling mine out and see know problems yet) Or changing it over to a manual glow plug system, but I hate to do that with all the money I spent on the controller.
Truck is nickel and diming to death, not to mention wearing me out.

 

The glow plug controller is not seeing enough resistance so it just keeps clicking. All eight glow must be working and drawing a proper load. Make sure the plugs going to the glow plugs are tight. Take a jumper wire from pos. batt.term. and strike it on top of each glow plug, u should see a good spark if glow plug is working properly.

 

Remember the Glow plugs are just to assist in the starting not the running of the engine You can just start the engine with starter Fluid (Either) even WD-40. A diesel engine is 100% compression by compressing the fuel to extreme pressure it cause the combustion that forces the piston back down. You might have a timing issue.

 

found an article on glow plugs and how to work on them at dieselhub.com good article but you can not copy the page, so i wrote it all out in my notebook I keep on repairs for my truck.
