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).

2000 dodge ram diesel 2500 . What is a fuel injection pump mechnical failure? a fuel valve feedback circuit?


This usually happens when the lift pump gets worn and fuel pressure drops below 7lbs and the injection pump has to work harder by pulling in the fuel and will destroy the pump,your is probably a vp44 fuel injection pump it needs replaced and they are expensive 1200.00+ but also change the lift pump or change to a fass fuel system,if the lift pump went out and you replace the injection pump it will ruin it in a short time.
The injection pump is not an easy job to change or for a novice mechanic as it has to be set in time with the engine at top dead center,and then the whole fuel system needs to be bleed of air.

99 ram diesel wont start


Did you check to see if there is power to the glow plugs if not then that may be the problem and if there is power when you cycle the key not to start but for the plugs to warm up you may have a bad glow plugs.

Dodge 3500 diesel lift pump


When the key is turned to the start position, the pump should run for about 20 seconds. Do this 3 or 4 times to prime the pump.

If it still doesn't start, the bad lift pump may have damaged the injection pump. Crack a fuel line loose (don't remove it) and turn the engine over, you should have fuel at the fitting.
