This has never happened before. My 2005 Dodge Ram 1500 5.7 HEMI engine just died while driving 50 mph on my way home. Engine shut off. I had indications and gauges on but engine shut off and I glided to a stop with no power steering or power brakes. No codes are set and I popped the hood to see if there was anything obvious, but all looks normal. Fluids all check out. I tried to start it back up and it acts like it wants to start but it won't. I placed the transmission back in park and tried to start it but it won't start. Any ideas?

 

Any codes? Can be quite a few things. You'll need to check if it's receiving spark and fuel. Could be fuel pump, crank sensor, ran out of gas, engine locking up from lack of oil or coolant. You get the idea.

If you pour a little gas or spray starting fluid into the throttle intake and it starts briefly, it might be fuel pump.

 

Check your IPM(Fusebox)
There's a common problem with the 04/05 models where the wheels kick up water and dirt into one of the little holes on the bottom of the IPM and this causes a circuit trace to corrode and break connection.
Usually the first thing to notice is that the parking lights don't work when you turn them on.

It's the same trace that suffers from this problem, and I had this exact problem. I knew my IPM was bad because parking lights didn't work, so I grabbed one from a wreckers and kept it in the truck until I could change it....well I'm driving down the road one day and the damn truck just stops, exactly like you're describing. Mine started back up though, so I replaced the IPM immediately after that and the problem went away.

You can use an IPM from an 04 or 05 only as far as I've been able to determine.
swap out the FCM on the IPM with yours and put the new IPM back in the truck. good to go.

 

Fuel pump went out. Fuse and relay were good and I had my wife turn the key to on but not start as that applies power to the pump to prime. I listened at the tank and nothing. No whirring sound and it was dead. Replaced the pump by dropping a near full tank myself and back in business. Thank for the replies.

For a 15yr old truck it was very clean without rust underneath. There is a bunch of dirt and rocks both on top of the tank and in between the heat shield and tank so bang on that thing before getting a mouth full underneath.

 

The pump ALWAYS waits until RIGHT after you fill up, to fail...... I don't think I have ever had a pump replacement on any vehicle, that had less than 3/4 of a tank of gas in it.

 

Glad you got it fixed. Just curious... how many miles did the pump last? What brand did you get?

 

This reminded me that I wanted to upgrade my fuel pump when I get all the other issues/maintenance worked out on mine - read that my year Ram at least has a stock 100gph fuel pump that is weak and its recommended to change to a 180gph pump instead.

 

I had this issue when I had my 04 and it ended up being a solenoid in a transmission shorting out and caused truck to stall anytime (one time I took a turn into a very busy street and that was scary).

 

How did you figure out it was the solenoid?

 

I took to a dodge dealership for an hour of diagnostic and they found the issue pretty quick.
