Question about Dodge Ram 2500

1 Answer

We have a 2000 dodge 24 valve 5.9 cummins pickup. it has a PO216 code. it has had 3 new injection pumps, new lift pump that should have taken care of that code. It has had a cam shaft censor replaced and crank shaft censor replaced, a new emc replaced and flashed. Sometimes it runs just fine and then acts up. When it was a the dealers he could not find anything. We've owned this truck since it was new. This has all happened within the last year. And actually the computer and injector pump and lift pump and censors within the last 2 weeks. Fuel pressure is 15 lbs. at idle and 14 at 2700. Ground has been checked. All I can think of is wiring but where to start, it all looks good.

The problem is the wires on the back of the lift pump. somewhere along the line there is a bad connection. typically at the back of the lift pump. if they get corroded sometimes they'll work and others it'll run poorly. Replacing the pigtail would be cheap, easy and do it yourself. Start there and you should have it solved in no time.

Transit pump code p0216 how can i fix this


P0216 DTC - Injection Timing Control Circuit Malfunction and this means the diesel fuel injection pump has a timing failure. This could be that the injection pump timing needs adjusted OR the failure is internal to the injection pump and therefore non-adjustable.

NOTE: If your vehicle is a Dodge Ram with Cummins engine then be aware that fuel delivery problems frequently cause this code. Prolonged fuel delivery problems can cause injection pump failure!

Symptoms of a P0216 DTC may include:
Low power
Crank, but no start
Hard start
Displays an intermittent stumble or miss
Engine may start and then stall
Engine may appear to drive fine but surge at idle


The most frequent cause of this code is a bad injection pump due to poor fuel delivery. Fuel delivery problems could be:
A plugged diesel fuel filter
An in-tank blockage
Air in the fuel due to a cracked in-tank fuel ine above the fuel level
Bad transfer (lift) pump
Injection pump out of time


Possible Solutions: First, simply check if your injection pump timing is adjustable. If so, check the timing and adjust if necessary.

If you think that you may have a fuel delivery problem, then check the lift pump operation. On Dodge Ram with the Cummins engine, the lift pump should produce about 45 oz of diesel in 25 seconds of operation. This can be performed by disconnecting the fuel hose from the injection pump and pumping the fuel into an approved container. Bump the engine over but do not start it. Then the lift pump will operate for 25 seconds. If the fuel is aerated, then check/repair fuel line and recheck.

With the fuel hose connected the fuel pressure should be 10psi. If the fuel delivery tests fail, replace the diesel fuel filter and recheck.

If it still fails then verify there are no restrictions in the fuel tank

Then replace the lift (transfer) pump. IT SHOULD BE NOTED that if this code surfaced after a routine fuel filter replacement or if you have any of the above symptoms after routine fuel filter replacement, then suspect the fuel transfer pump. This occurs because even a weak transfer pump can still provide enough fuel for the engine to run. But when the fuel system\'s prime is lost due to fuel filter replacement, it may not restart again without fixing the fuel delivery problem.

If you found your injection pump to be bad, the lift pump should be checked for operation to protect the new injection pump. This is because weak or low output from lift pump are common cause of injection pump failure. There are some aftermarket kits that can be purchased to warn the operator when the fuel pressure/volume drops to level that could damage the injection pump.

Hope this helps (remember to rating this free answer and leave a testimonial comments).

Where is the fuel return check valve on an 98 24 valve cummins


I assube you mean a B. All 24v B's have three possible places up to '03. One the rear of the head, between it and the fire wall. Two, above the lift pump, the large line T's from the head and the pump returning to the tank. Three, at the rear of the injection pump on the mount. Can't miss em. They are 3/4" or 19mm (same size). Good luck

Oil leak


its something you can do your self but quit difficult. remove injection pump, special tool needed to get the gear off. the lift pump, the ecm. all injection lines and any thing and everything that gets in the way. sensors, coolant lines. to be honest, for a little more cost the head can be removed and new gasket installed. i would rather recommend a customer do that for the same time as just the tappet cover gasket. good luck
