Hi Geralt. In June this year, the engine turned over but would not start. After finding and replacing the blown 15 amp fuse, I had no more problems till I was on holiday in Scotland in September when the vehicle failed to start one morning and the 15 amp fuse had blown as did a spare I had. The breakdown man tried putting a 20 amp fuse in and it started and ran ok. I came back home and ran till early this month. On starting one morning the 20 amp fuse blew and the Alphard is now stuck on my drive. I have taken the combined filter and pump out to be tested. Due to it been an imported vehicle I have not found anyone who has a plug in diagnostic to find the fault code. 

Thank you for interest and help.

The EFI fuse supplies all of the engine control components not just the fuel pump so you might have to check the current draw on the following suspects:

• Fuel Pump motor
• Evaporator solenoid
• Idle Speed Control Valve
• Oxygen Sensor heater

The ECU and MAF are unlikely to be the cause.

 

You could feasibly disconnect the oxygen sensor and evaporator and still run the engine. If the fuse doesn't blow then it could point to either of those being the culprit.

 

 

Thanks for that Geralt. I will progressively check them out.

My 2004 2.4 petrol vehicle keeps blowing the 15 amp fuse on the fuel pump circuit when starting. Has anyone any experience of this?
