I have a dodge sprinter and it does not show what gear it is in?

On my dodge sprinter (1994) it does not display the gear it is in on the dashboard. it is a diesel automatic engine. I have checked the fuses and that does not seem to be the problem. it is as if the car does not know it is in park and will not try to start, as if you were trying to start your car form the drive position. the starter does not try to turn. if you could give me some ideas on possible problems that may be causing thin it would be great.I have a dodge sprinter and it does not show what gear it is in?
The neutral switch on those have a ground feed wire that runs to the starter relay, what could be happening is the relay has no ground therefore the starter won't engage at all and the comp system could cause the transmission gear indicator to either display every gear light to be lit all at once or none at all.



Here's a few tests you could do pop out the starter relay and check the relay sockets pins one pin should have a positive 12 volts another should have a solid ground signal.If you've got these two pins working as I've mentioned then try turning the key into the start position and another pin on the relays socket should now give you a positive 12 volts.



If when you try to start it without any starter relay in it and you've now 12 positive pins and a ground or negative pin try popping in another relay in its place and then starting the engine.Note you should find other relays with the exact same part number in the fuse box under the hood , you can switch a non vital relay with the starter relay , example fan relay , try it if its starts , be sure to replace the missing fan relay and not to run it unless you do.



There is a trick I use during this next test if it doesn't start then I take some wire not too thick maybe 18 gage or so peel it's end and wrap it around the pin of the relay that plugs into the relay socket pin that connects to the wire going to the starter and then be sure the wire isn't shorting out any other relay pins as you pop the relay in firmly.Now peel the other end of this wire and connect up 12 volt test probe to it or volt meter and when you turn the key to start the engine that probe should be lighting up.If probe lights up check relay again and then check the wire going to the starter from that relay.



You can use this wire trick for the tests mentioned before too just to double check.Basically one relay socket pin should have a steady ground and another pin gets a fused 12 volts so if no pin is live with a positive 12 volts , check the fuses closely.Again once you know these pins are live , when you turn the key the ignition feeds the relay power and if it's not doing this via a relay socket pin check the ignition fuses closely.



You can buy a handy test probe it tests both positive and negative current and this probe is perfect for what tests you need to perform, also some places sell service manuals like Haynes for about 20 bucks or so and some parts stores will print out free diagrams and starter relay , ignition , wiring info and diagrams.



There could be a bad ground going to the display or a short in the wiring causing the system not to display or to turn over but check the battery, all fuses and the charging system just in case.













Hope that helps and best of luck.By the way if you can get comp pin layout out and wiring info too that would help, bec a comp could be shut down due to a12 volt feed or bad fuse or bad wire or sensor , so try to get the system scanned if possible just in case any error codes exist.I have a dodge sprinter and it does not show what gear it is in?
if the neutral safety switch goes out on it ,it will do that ,but it wont make the lights on the dash not work,you need to try and see if it has lost a ground wire somewhere,it sounds like its lost a ground or the ignition switch has went bad on it,good luck on it.
