Heat is caused by excessive amps being pulled through the fuse. Sounds like the pump is on its way out. If all connections are clean and wires are in good shape, I would save myself a tow and go ahead and put a new pump in.
how do you prime an electric fuel pump thats buried inside a fuel tank ---are you getting fuel to the throttle body --is pump turning on --retest pump new doesnt mean free from defects if this is the first replacement pump for vehicle was the connection to pump upgraded /changed out [problem with connection corrosion and damage would incur causing pump failure or non operation of pump ]also check lines are not kinked and pump installed correctly

fuel pump? I would highly recommend replacing the strainer, filter, and possibly fuel lines at the same time. these can get plugged up with fuel varnish/other junk, and cause power loss and also cause the new fuel pump to fail quickly. Fuel pump manufacturers also will not honor the pumps warranty unless these other parts are replaced at the time of installation of the new fuel pump.
Guys, the OP said "mecanical fuel pump", not power steering or watter pump!..
The first time may have been normal fuel pump diaphragm wear... and the second fuel pump may not be the correct part for the engine... the pump lever is a different size for different applications.. if you got the wrong fuel pump the pump lever coud have been of the inappropriate size and may have caused excessive fuel pressure or to long diaphragm travel rupturing it. Make sure that you get the exact fuel pump for your car before you pay for it. Otherwise if the fuel pump you bought was the correct part, it may have been deffective.
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.

FUEL PUMP MORE LIKELY WORN OUT SHORT OUT.BESURE REPLACE FUEL PUMP WIRES IF FUEL PUMP HAS TO BE REPLACED.CODE SCAN FOR ECU FAULT. IF FUEL FILTER STOPPED UP FUEL PUMP WILL SHORT OUT.
Burned contacts in the fuel pump cutoff switch can cause this as well as a burnt connector to the cutoff switch, the relay for fuel pump can also cause this problem.
The possible causes are a dirty fuel filter and since the fuel pump sits in the fuel tank and is cooled by the fuel, always keeping the fuel level at low or empty which causes the fuel pump to run hot deminishing its service life.
the fuel pump and radio are not on the same circuit, most liokely the fuel pump is shorted, that is the most common cause, get under the truck and disconnect the fuel pump connector at the tank, if the fuse doesn't blow then u need a new pump.
