Fuel Pump Failure

When the engine dies the Check eng light is supposed to come on. You need to do a fault code test on the OBD2 engine control module.

Fuel pump intermittent failure works when it wants to your fuel pump is shot replace it your truck will run good agian

there has to be a gasket failure somewhere..doubt if the truck has a mechanical pump on it but if so equipted the pump diaphram has failed and is pumping raw fuel into the engine block.. replace this pump and the issue should go away...most pumps were mounted in the fuel tank and are electrically operated..so it may be a tbi gasket failure or line leak somewhere check all and repost findings..thnx

which engine

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.

According to msn.autos

Occasional problems on this vehicle are plugging of the Exhaust Gas Recirculation (EGR) Valve Passages (2.4L engine only) and failure of the Fuel Pump Sending Unit Assembly Connector Terminals. Plugged EGR Valve Passages may cause the engine to misfire and may also cause the Check Engine Light to illuminate. Failure of the Fuel Pump Sending Unit Assembly Connector Terminals can cause loss of power to the fuel pump leading to a crank and no start or an engine stall while driving. A periodic problem on this vehicle is failure of Distributor Assembly (3.3L only). The cost to repair the EGR Valve Passages is estimated at $10.00 for parts and $130.00 for labor. The cost to replace the Fuel Pump Sending Unit Assembly is estimated at $206.41 for parts and $195.00 for labor. The cost to replace the Distributor Assembly is estimated at $370.00 for parts and $39.00 for labor .All prices are estimates based on $65.00 per flat rate hour and do not include diagnostic time or any applicable sales tax.

i have a 2000 nissan frontier that dies going down road,it has knock sensor,camshaft sensor&primary ignition circuit failure.had a new distributor.thanks for any help

SOUND LIKE FUEL PROBLEMS.CHECK TO SEE IF FUEL PUMP IN MODULE IS RUNNING.IF NOT CHECK FUEL PUMP FUSE OR RELAY.IFALL IS GOOD CHECK FUEL PUMP ELECTRICAL WIRES CONNECTIONS MAKE SURE THEY ARE TIGHT IF ALL IS GOOD.FUEL PUMP BAD.IF FUEL PUMP IS WORKING.PROBLEM COULD BE STOPPED UP FUEL FILTER. OR PROBLEM IN THE FUEL INJECTOR CONTROL MODULE OR MECHANICAL FAILURE IN THE HIGH PRESSURE OIL PUMP.

look 214 is not a valid code for a 1995 escort, this is an OBD1 system. here is a list of trouble codes for this year of ford no matter the model.

You should find the diagnostic connector under your hood normally by the fender on the battery side. By just using your test light and a jumper wire, it will tell you what kind of problem you got.

KEY ON ENGINE OFF (KOEO) TEST
Model years 1984-1995 all models of Ford
1. Make sure engine is fully warmed. If in doubt, run engine at 2000 rpm for 2 minutes.
2. Turn ignition off and wait 10 seconds for system to shut off. Make sure A/C is off and transmission is in Park (automatic) or Neutral (manual).
3. Hook up light and jumper (or a tester if you have one). Turn key to ON (do not start engine). Read the codes.

How to do it?

Example code 23: your test light should flash 2 long consecutive flashes followed by 3 short pulses.

Kelly;
Funny this truck ran good 1 day and not the next. 1 of 3 problems;
1.Injector pump failure, plastic part inside. Notorious failure.

2. Fuel pump failure.

3. When you filled up at the station, you may have got a dose of water in the tank. I would check this first by draining fuel and looking for water. If you find water, more than usual, you may have an insurance claim against station.
