05 dodge diesel remote start trouble

You might need one of those fancy pulse timer doo-hickies. Not being a DEI guy, I don't know if the wait to satart can be timed, or needs a glow plug trigger.

Someone might chime in with this info.

When it's cold this truck want's (needs) 30 seconds to heat the plugs. Summer.....no problem as you have seen.

The 06 is 10 to 15 seconds delay.

ask the isntaller where he got the tach from. best is from injectors.

you want a wait to start wire..... it's at the glow plug solenoid . behind the air filter box. under hood.

Find a BROWN / orange. it will show 12volts ONLY when the engine is cold.

This is why it's BEST to time the starter.

I would check to see where your installer is attaching your tach wire.  He may have attached it to 12 V+ and it is set the starter to use voltage sensing instead of tach signal. If you find this to be true, This is what was happening on my 05 3500 RAM. 

The vehicle starts and runs until your glow-plugs cycle back on (If you ever listened they will repeat this until the truck reaches a certain temperature or time has elapsed). The starter notices the drop in voltage because of the heavy draw from your glo-plugs and shuts the remote starter off because it thinks the truck stalled because from the drop in voltage.  If you notice your alternator does not put out any voltage until you reach 20 MPH or an operating temp. I think this just adds to the problem as if it was sending out the normal voltage it would overcome the voltage drop from the glow plugs.

When it was pretty cold outside, my truck would start, run for 15-20 seconds and shut off just to start again and again.  This would repeat this until the truck reached a high enough temp that the glow plugs would stop cycling. I never monitored the voltage in my truck to verify this is what was happening but I believe it was the case.

The two fixes for this would be to change the system to a tach sensing or a timer mode.

I hope this helps.

Thanks for the info.  Now how can i change the setting without a handheld programer?  Does anyone know someone in Phoenix that has one i can pulg into without charging me a arm and a leg.  I know that the tach is attached down on the driver side of the motor but i dont know if the sensing is set to volt or tach the first time it was installed the tach wasnt hooked up and my installer said it wasnt necessary.  But this problem continued to occure.  The voltage serge makes good sense because all the lights will dim when the heat grid turns on. 

I know that this isnt a mechanical site but just for clarity dodge cummins engines dont have glow plugs they have a heat grid on top of the manafold.  only ford and chevy still use glow plugs when it comes to light duty diesels.

What model Viper do you have in your truck?

hmmm good luck with that idea on a diesel since its mechanical fuel injection....anyways back to the topic on hand, your tach wire should be hooked to a blue/gray wire on the front side of the PCM.  The PCM is attached to the driverside of the motor about halfway down.  This is the crankshaft position sensor wire and is the most accurate tach signal on a diesel motor
