Sat for 3 years running when we stopped driving now it wont restart. chkd fuses, relays, b


Fuel is probably stale. Pump or pump relay might be stuck.

I suggest you check the fuel delivery to the fuel rail. If no delivery the pump isn't working and the supply should be checked and then take the appropriate action depending whether the supply is good or not.

Fuel rail pressure code 43 / Po191


Check to make sure the fuel pump is working. If the fuel pump is not working check the fuel pump fuse and fuel pump relay, also check to make sure the inertia cut off switch hasn't been tripped. If the fuel pump is working then check the fuel pressure regulator.

How to troubleshoot a no fuel problem, no fuel at fuel rail in a 2000 olds sillhouette.


First check there is battery voltage to the pump and the pump starts when the ignition is switched on , if not check fuse and relay, check wiring from relay to pump. If ok and the pump is working , check for fuel blockage from the tank inlet to the pump , some have a sock type filter in the tank pick up tube, if all ok remove the fuel filter , switch on and fuel should flow at the filter, fit a new filter, if still no fuel at the rail fit a fuel pressure gauge an check for low pressure , if ok, the fuel pressure regulator may be stuck causing a air lock replace it.

What controls the injector pulse on a 2002 buick rendezvous?


michaelvolla,

All fuel enjected vehicles have a fuel pump relay that controls the pump action when pulling (pumping) fuel to the fuel rail.

If you are experiencing lack of fuel to the engine, chances are that the fuel pump relay needs replaced.

To determine this, answer the following:

1. Is there fuel pressure on the fuel rail after shutting the engine off (at operating temperature) one hour or more after shut off?

If so, then it may not be the relay. It could be the sending unit (fuel pump) itself, but it feul pressure is not present upon pressing the needle in under the black knob on the fuel rail; replace the fuel pump relay first. If this doesn't work, then the fuel pump may need replaced.

Please let me know if you need anymore assistance, or further questions or concerns. Also, inquire abou this with a local parts dealer, as they will also be able to help you in this matter.

The relay and pump are something that you should be able to do yourself, and not have to go to a mechanic or dealer to have replaced. Unless there is extraordinary work invloved, which I highly doubt, but is possible.

Cordially,

Dodge caravan turns over wont start all lights work


possible bad fuel pump. check fuel pump relay under hood. drivers side fuse panel. swap fuel pump relay with another identical relay to rule out possible bad relay. listen for whining sound back by fuel tank. the fuel pump is in the fuel tank. Another option....you can also check the pressure in the fuel rail, but be careful not to squirt gas in your eyes or face.

No fuel pressure


Sounds like a bad fuel filter, or fuel pressure regulator. If there is no pressure to the rail, the fuel filter is either clogged, or the fuel line is broken or kinked somewhere between the fuel pump and fuel rail.

94 dodge grand caravan no fuel in fuel rail


Dear Ron, you have replaced fuel pump and fuel filter. You have checked the fuel pump relay. Still no fuel in rail. Try bypassing fuel relay with jumper from batt to fuel pump. If o/k then check computer for ground to relay. This system uses a relay that is operated by the computer that supplies a ground for the relay to operate. The wire color is green,16 gage. If the ground is not available then "no fuel" Check this with a test light. Key on and crank apply test light to ground wire and other end of light to ground. You should hear relay click and get fuel. If this checks out you will need to replace computer or get creative with rewiring the relay so it works without computer input. Good luck Moe
