Question about 1997 Isuzu Rodeo

1 Answer

No power to Fuel Pump

I am not getting any power to my fuel pump. The engine turns over fine but I can't get it started. It has a brand new fuel pump, fuel filter, and alternator. I checked the relays and the one for the lights is working so I switched it with the fuel pump relay and still nothing... Any answers?

We have replaced fuel pump in a 98 ego metro LSi drove home ran fine. Now it won't start any ideas why it won't start.


Pam, was the fuel filter replaced at the same time that the fuel pump was replaced? If not, replace the fuel filter. Often, the filter will get clogged with debris. When that happens, the fuel pump will be ruined. Replacing the pump without replacing the fuel filter can ruin the new pump. It is also possible that your new fuel pump is defective. Now that most replacement parts are made in China and the third world, there is virtually NO quality control. I'm a professional mechanic and defective brand new parts are a BIG problem in this industry. Was the fuel pump relay replaced when the new fuel pump was installed? Always install a new relay, as a failing [your old] fuel pump will often damage the relay. This will cause problems with the new fuel pump. I would advise that you install a fuel pressure test gauge to the engine. This will allow you verify whether or not the engine is receiving enough fuel pressure. If the pump works but the pressure is low, also check the fuel pressure regulator. The web links below should help you.

FYI, there is also a "sock" style pre-filter on the fuel pump. This also needs to be replaced any time that you replace the fuel pump.

You cant check fuel pressure that way. You have to connect a fuel pressure guage to the fuel rail at the schrader valve. It should have 30-40psi when ignition is turned on. Injectors not functioning properly will cause a misfire Sounds like a fuel pump or fuel going out.

1999 Ford Explorer Sport Starting Issue


It sounds like the pump is failing. That or sometimes not getting electricity. To check which it is, you could use a voltmeter or test light at the gas tank's electrical plug in. You need to check for power on the fuel pump wire when the engine is being cranked for starting. Do this when turning the key to on does not cause the pump to turn on for 2 seconds as it should. The fuel pump has power for those 2 seconds when key is turned to on, and again has power when the engine is cranked. You might miss the two second signal, so check for power when car won't start-when pump won't turn on-and with the engine cranking. If you have a signal then and still no pump coming on, then you must have a failing pump.
But if you have NO power to fuel pump wire with engine cranking, then it is a problem elsewhere-probably the pump relay (try a new relay if you haven't already). That relay is signaled by the engine computer when key is turned to on or when engine cranks . so you could do some testing at the relay if needed.

is your fuel pump on check for a safety cut off switch to see if it needs to be reset. if not a power to pump problem could be your pump sock is plugged or the pump has failed.

I have a 91 s-10 that wont run...fuel pump runs and I am getting fuel to the carb all brand new plugs and wires and ignition coil and module and new cap and rotor? fires up and dies out?


The fuel pump relay is at fault. The engine will start running off the oil pressure sensor for the 3rd wire connected to the sensor feeds power to the fuel pump which makes your truck start right up. When the engine achomplish the standard oil pressure as needed the sensor shuts power off by the PCM default system and turns on the fuel pump relay to continue working the fuel pump. replace the relay and you will be driving around again

Did you replace the fuel pump with a NEW fuel pump, or a used one?
Get in the car, insert key and turn to "On". Do not attempt to start. Do you hear the fuel pump run for a few moments? Try it a few times, starting the car each time after you hear the fuel pump run. If the fuel pump does not run, then chances are, it's a bad fuel pump.
It could also be the fuel pressure regulator, located on the fuel rail.

Your statement about the oil is confusing.
