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.

Could a po178 code cause repeated fuel pump failure on a 2003 chevy tahoe?


No that is a Flex fuel sensor that detects the amount of Alcohol in the fuel and signals the powertrain computer to make changes to accommodate the fuel to the engine controls system. Here are common causes of early failure. 1.Did you replace the connector to the fuel pump? They sell a repair connector, it must be replaced anytime the pump is replaced or early pump failure will occur, the new connector must be soldered on and shrink tubed, no quick crimps should ever be used.. 2. Are you running the fuel down to or below 1/8 tank? This severely overheats the pump and causes early failure.. And lastly what is the average miles you are getting out of the new pumps?

Fuel pump


The fuel pump module contains the fuel pump and the fuel tank level sender for the guage and all the connections for it and the cap. The noises that you hear are the pump working and it is most likely because it is vibrating. This a common occurance and is annoying. There is very little chance that it is an idication of a failure that is coming. During manufacturing there is supposed to be a vibration damper that is installed to keep the pump vibration from transmitting to the hard fuel lines. Your pump might not have had that.

Failure to start. then will start next day. Mazda said it was fuel pump. They replaced $790.00. did not resolve problem. they kept 2 days and said it was battery. Replaced. @ weeks later same problem.


Well, they probably did put on either a bad fuel pump or should've done the relay.There is also a fuel pump REGULATOR that can cause a lot of trouble. Make them keep at it,since their work should be warranteed when they say they've fixed it. don-ohio

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).

did they change the fuel filter at the same time?a bad filter will cause the fuel pump to overwork and can cause premature failure.you may also have a fuel pump relay going bad,it is probably located in a fuse/relay box under the hood.

1993 CAMRY HAS BURNT 3 TIMES THE FUEL SYSTEM FUSE.


it could be a couple of problems. your fuel filter may be clagged causing a lot of resistance in your fuel line. or if your pump is worn out it will cause a lot more resistance on the electrical part of your fuel system. if your fuel pump is going bad it will do better with a full tank of gas since your pump is submerged in fuel it stays cooler.

Pump was loud then not replaced worked for week then same


Lower voltage is just as bad as too much. Check to be sure the entire fuel pump system has proper voltage. I myself would start at the pump that will save you time if it ok.

1996 gmc yukon. replaced fuel pump 3 times in 2 months, finally running then it wouldnt start one day. cranked it over for awhile and nothing. sat 15 min it started right up, drove home shut off, then...


this is a very common problem. GM has issued a service bulletin to replace the wiring connector at the fuel pump assembly on top of the tank. check the end of the plug for burnt terminals. the service bulletin states that these corroded connectors cause a voltage drop that results in repeated pump failures.
