Question about Onan-Orderable Cummins Onan 2.8 KV-FA/ 26100 RV generator set RV QG 2800

1 Answer

Have spark but not getting fuel. What type of fuel pump does this unit use. I am under the impression that the pump is an interval pump, meaning the power going to the pump is constantly switched on and off. If this is the case, how is it controlled? If I run a straight 12v to the pump clicks firmly but not continuously. if I pulse the 12v then the pump seems to work. When the engine is cranked over, I can feel the pump kick on but does not pump. Just feels like it takes a single stroke. If the power to the pump has to be 'pulsed', how is that controlled?

What side is the fuel pump for 2002 lincoln ls v6


2002 Lincoln LS uses a saddle-type fuel tank consisting of 2 fuel pump modules. A fuel transfer pump in the left side of the fuel tank supplies fuel to the right half, which contains The Fuel Pump Module (FPM). The FPM contains the fuel level sensor and an inlet filter. The FPM is controlled by the Fuel Pump Driver Module (FPDM) which is integrated into the Rear Electronic Module (REM) Fuel pressure is regulated by a pulse-width modulator in the FPDM which cycles the fuel pump on and off at varying intervals depending on engine load and RPM. The FPM supplies fuel under pressure to the fuel injection system supply manifold and a fuel level signal to the fuel gauge on the instrument panel.
It is recommended that if one of the fuel pumps fail that BOTH pumps be replaced as a set to avoid repeat repairs. (If one pump has been running for 1500 hours and the motor is worn out, the other pump also has been running for 1500 hours and is very likely to fail shortly thereafter.)

Lancer cut out while driving. will turn over but will not start. it has fuel but no spark.


check mass air flow sensor or crank sensor. If those are not working then the car won't run. is there a check engine light on or a battery light on? obtain an obd2 scanner from an auto parts store and download the code. that will usually tell you everything you need to know. also, check to make sure youre actually getting fuel to the engine. you might have a weak fuel pump. prime the fuel pump a few times before trying to start the car by turning/cycling the key from off to on, not start*, in 2 second intervals a few times then try to start the car. you might be able to hear the pump running under the back seat.

hope this helps!

I have a 2000 chevy cavalier not starting, had fuel pump changed 3 weeks ago and worked fine until this morning at that time i also changed spark plug wires and plugs and today changed the ingnition coils


i will try to help. with the key in the on position, do you hear the fuel pump humming? that is a must!! you may have to turn the key on and of for 15 second intervals to hear it for sure. if the fuel pump is humming, that means it's at least pumping. you'll need to narrow your search to this, is it getting fuel? or is it getting fire? that will narrow the search field. if it's getting fuel, but no fire, have you checked the crankshaft sensor? have you also checked all the fuses in the black box under the hood?when you changed the coils did you get everything plugged back in correctly? jusy trying to cover some bases with you. hope this helps!! thank you for choosing fixya.com

Car turns over but won't crank. spark plugs are


Turning over and cranking are often the same thing, so Im not sure what your asking... Do you mean the car turns over but wont fire, or start? If thats the case and as you say the plugs are getting spark, then your problem is gonna be the fuel pump 99% of the time... Try this little trick, have a friend hit the fuel tank from under the car with a NON metalic hammer (ie a rubber or wooden mallet or chunk of solid wood etc) while your trying to start the engine. If the car fires up, then dont risk doing that trick again as it probably wont work twice, and get it to your mechanic to get a new fuel pump installed. If it doesnt work, (it really is a 50/50 thing) then get it towed and have the fuel pump changed as its still probably the problem...

1996 GMC Suburban - Quit Running While Driving, Will Not Start


Listen at the back by the fuel tank for a 1 to 2 second prime cycle whirr from the tank when turning the key to run position after it has been off for at least 10 seconds.
No noise means no running pump.
....and no noise means.....
Most likely it will need a new fuel pump....80%
Fuel pump relay 10%
Fuse or bad wiring 10%

The quick fix to get home is to crank the truck to create oil pressure to fire the pump......and while cranking WHACK the tank hard with a 2by4 or something like that....to jar the pump..... and it may start running long enough to get it somewhere to be repaired.
This works 60% of the time on a dead pump.

If you do hear a whirrr.....you most likely need a ignition module or crank or dist pickup.

Need to locate fuel pump on 96 jetta


1996 Volkswagen Jetta 2.0L SFI 4cyl

On a Digifant fuel system, the fuel pump is mounted in a reservoir under the rear of the vehicle. The fuel filter is also in this area. The reservoir holds one liter of fuel and is supplied by a small transfer pump in the tank. The transfer pump can be replaced separately even though they are installed and removed as a unit.

The Motronic system uses two fuel pumps. The first is a small transfer pump to get the fuel out of the tank and the second boosts the fuel pressure to the necessary amount. The transfer pump is located inside the tank and the main pressure pump can be found under the vehicle. This transfer pump is located under the rear seat and is part of the fuel gauge sending unit. The main fuel pump can be found in the reservoir in front of the rear axle beam. There is a check valve inside this pump to maintain pressure in the lines, especially on hot days, to avoid vapor lock. The fuel filter is mounted to the side of the reservoir. This filter has no specified replacement interval and should be good for the entire service life of the vehicle. Whenever the ignition key is in the on position, the pump should run for at least two (2) seconds to pressurize the fuel lines. If the Engine Control Unit (ECM) does not see a signal from the Hall Effect sensor in the distributor it will shut the pump off. If a Hall Effect signal is present, the pump will continue to run as long as a signal is detected. It is this Hall Effect signal that signals the ECM that the engine is rotating therefore indicating that fuel is needed. The pump is operated via a relay that is controlled by the ECM. This relay is located in the vehicles fuse panel. The main contacts of the relay can be jumped to run the pump during testing.

Good luck (rated this help).

Will not idle


fuel pump is in the tank. first get a spark tester and see if there is spark.if there is ,get fuel spray into the throttle body and see if it starts then dies.that would mean a fuel problem.sometimes banging on the tank gets the pump working again.take the cap off and have a look inside.
