Ram 2500 Diesel Leak Back Problem? by irishjim1

I own a Dodge Ram 2500 with Cummins Diesel 4X4 bought new in 1996. Been a great truck. Now has 184,000 miles. It's having starting issues for several years now, traced to a fuel retention problem. If I park faced downhill it usually starts fine. I had the fuel pump replaced but didn't fix problem. Recently I discovered if I jack up the rear end and crank the bleeder for 20 mins I can usually get it up and running again, of course this is just a band aid. I would really appreciate a final fix for this problem. My normal mechanic has been un-able to solve this problem. (Though he's been wonderful with our gas vehicles)
Thanks for reading.

04 diesel won't start when warm? by ramit3

Here's a good one for you techs.. 04 2500 5.9l 300,000 kms. Problems with very noisy engine. Dealer replaced #1 injector, still noisy, brought it back. I was with tech while hooked up to computer. When he shut down # 6 injector sounded ok. So I said pull all inj. out and test. They all failed. They replaced with remans. All was ok for 5,000 kms. Started to be hard to start when at op. temp. I replaced fuel filter. Did not help. Continually got worse. to the point where it would not start. Had to leave for 1+ hours before it would start. Brought it to another repair shop which specializes in small diesels. Lift pump tested ok injector pump tested ok. no codes. They felt it may be the reman injectors because the electrical parts in each inj.can't be rebuilt. Stated that 20% of fuel is injected into cylinder prior to normal time before TDC. When inj. are hot this may not happen. Brought it back to Dealer for more testing. I relayed this info to them. They are still testing and talking to the reman company. They say it is not the inj.s. They really don't know what the problem is. Also, when in no start condition engine sounds quiet as if no fuel. Give a little sniff of starter fluid and jumps to life.When running sounds good, power is good fuel economy is normal... Any ideas????

This should be an easy problem to troubleshoot since its very consistent. Ignition coil voltage, injector voltage, and fuel pressure should be monitored at a first start-up scenario. This will confirm the problem right away.
 
I don't see or even hear of very many bad injectors on Dodge gas engines, unless they have a lot of miles (>100,000) and have had a steady diet of cheap fuel. One punky or completely inoperative fuel injector would not explain a no start condition, in my opinion.
 
Just a hunch, but I'm suspecting you might not be getting ANY injector or ignition coil voltage at that initial start, or no fuel pressure. I have worked on two Dakotas with this symptom and found that after replacing the ASD relay the problem did not return. The techs at my local Dodge dealer have also told me they've found bad connections in various connectors or ground points that have caused the same problem. I know of one RAM that had a bad fuel pump relay that caused a no start condition similiar to yours. The Fuel Pump Relay is of the same type as the ASD Relay.

Dusty

This could possibly be caused by an intermittent ASD Relay, Fuel Pump Relay, bad electrical connections, or a slow Fuel Pressure Regulator.

I have to say I honestly don't know, although I'm sure there's a fuel pump relay. I'm not sure about an Automatic Shutdown (ASD) relay.
 
I apologize. Since the days of full-size GM cars, I have successfully avoided having anything to do with diesels, and my knowledge is very limited with respect to the Cummins version of the RAM.
 
Best regards,
Dusty
