Hi I have a 2.6 microbus I'm not getting any power to my fuel pump what can be the problem and where is the fuel pump relay located

HI possibilities are ignition module ,ignition dry coil ,fuel pump relay. Do test fuel pressure for consistent flow, DO a diagnostic check for a final report .

Hello everyone, please forgive me for the question but i honestly can't seem to find the answer to it. I want to change my fuel pump relay in my 2003 745Li. If I'm not mistaking, the fuel pump relay is located in the trunk next to the battery. I did notice the green cube looking thing (fuel pump relay) in the trunk but there were two of them. Do i need to purchase two fuel pump relays? Any insight would be greatly appreciated. ??

fuel pumps get their power when the ECM gets a report from the pressure regulator that more fuel is needed
on getting that report the ECM triggers the relay which then clicks and passes power to the pump
places to check
wiring and connections from the regulator , ECM and relay ground

The click you hear is probably the fuel pump relay. See if you can locate it by sound. Possibly, the power feed for the pump may not be good at the relay. Pull the relay out and check for a power signal at one of the terminals that the relay plugs into. It should be a hot- at-all-times signal, so the key does not need to be on. The power feed will come from a maxi fuse in the power distribution box, or from a fusible link just off the battery. If the power is good, try another relay. If still no pump, check the wire from the relay to the pump for a short-a broken line. If wire is good, check the ground for the fuel pump.
Go back to your checking for power at the pump: just possibly, you missed the signal with the key on, because with key on the pump is only supposed to turn on for about 2 seconds (to pressurize the lines) and then shut off until the engine is cranked or running. Try testing for power again at the tank with the key held in start-should be a steady signal then, as long as the engine is cranking over. If still nothing, back to the relay. If you now have a signal for the pump when cranking engine, it must be the fuel pump ground.

Hi Jered, I believe all high pressure fuel pumps have relays. The one in your vehicle will be under the hood. Regards John

The relay and fuse is located under the hood in the relay box. It will be labeled on the lid. If fuse is good, then test the relay. Pull it out and with a test light see if there is power. If there is then remember that one. Have some one turn the key on and find another power wire. There should be 2 powers.If there is only one power then there maybe a problem in the ignition switch. If there is 2 powers then you need to get to the top of the fuel tank and see if power is getting to the pump. The power at the pump will be there for only a few seconds once the key is turned on and then will drop off. Let us know how it goes.

Hi..my name is Keith..and the 2 things that i know of...that will not let power go to the fuel pump is 1..the fuel pump relay being bad..or 2..that something has tripped the Inertia Switch...and it needs resetting..i hope this will help

There is both a fuse and a relay for the fuel pumps electrical system. The image below of the Power Distribution Box is located in the engine compartment.

Fuse/Relay Location: 5
Fuse Amp Rating: 20 Amp Mini Fuse
Power Distribution Box Description: Fuel pump

Fuse/Relay Location: 203
Fuse Amp Rating: 1/2 ISO
Power Distribution Box Description: Fuel pump relay

My vw caravelle bus 2.6i -1996 model cant start- just cranking but not firing, cant hear the pump click as usual. It was just running fine, then switched off, when i got back all these started. kindly assist.

Hi I have a vw microbus 2.6i the oil light and a biz sound comes on and off even if the oil is right. what do I need to do
