theislandnut Posted December 8, 2015 Share Posted December 8, 2015 It was running perfect yesterday. I get in today and no start. The oronge glow plug light was working before and this morning it didn't come on but a red water in the fuel light next to it did. The fuel heater/filter/water seperator is new and was loose where it attaches to the fire wall, so I grounded it and tried again and nothing. Then I drained it and reinstalled and still nothing, the red water indicator is still on and the glow plug isn't If anyone can point me in the right direction that would be great.

HOrnbrod Posted December 8, 2015 Share Posted December 8, 2015 Did you ohm out the glow plugs? If any tested bad, grab THESE on Ebay. These are correct for your diesel and are a steal at the price. Link to comment Share on other sites More sharing options...
theislandnut Posted December 9, 2015 Author Share Posted December 9, 2015 Thanks. Those are cheap. I have been wrenching and building jeeps for years but this is my first diesel of any sort. I know the basics and have been cramming the books since buying it. If it's not reliable enough to DD then it will be sold or heavily Nuttered. When running it runs very well and all though it's low miles every diesel specific part is new and I have the low miles take offs as spares. I have not had the time to look at it, seeing if there is at least 10 volts at each glow plug 'GP' will be the first thing I check. Then the indacator bulb as an open circuit there will not energize the GP timer. I am wandering why the water in the fuel light is still on and if being on it activates the fuel shot off solenoid.

johnj92131 Posted December 9, 2015 Share Posted December 9, 2015 Glow plug fuse? Early VW diesels had a 50 amp fuse, when that fuse blew, the glow plugs did not work. And the car would not start. Should ask if the engine turns over but just doesn't start. Link to comment Share on other sites More sharing options...
theislandnut Posted December 9, 2015 Author Share Posted December 9, 2015 Turns over just fine, no smoke or diesel smell. I pulled and inspected every fuse under the dash and all were corroded and oxidized. Seams that it's just a standard fuse panel and that anything diesel specific is in the engine compartment.

johnj92131 Posted December 9, 2015 Share Posted December 9, 2015 Check with Automan2164. He is quite familiar with the stock diesel MJ. On the VW, the glow plug fuse was on the fire wall in the engine compartment. I don''t have the MJ diesel manual, so can not help more. Another thought, to check for fuel flow to the injectors - crack the fuel line loose at one of the injectors. Then turn the engine over. You should see fuel leaking from the cracked injector connection if the pump is sending fuel to the injectors. Link to comment Share on other sites More sharing options...

theislandnut Posted December 9, 2015 Author Share Posted December 9, 2015 It's a DIESEL Jeep that a wine drunk Frenchman thought up while hurling into the la trein, Bad wiring and contacts on the diesels engine harness. I cleaned the wiring all up, unplugged everything cleaning the contacts then read drained the water seperator. It fired right up. Link to comment Share on other sites More sharing options...
