ECU fuse blows and engine stops when accelerating, help please!

[Nadlam]

Hi folks, first post here on the forum. We have a 1995 Bongo which we’ve owned since October. Two days ago I broke down after the engine just stopped whilst accelerating up a hill and called the AA. After diagnostics, he found the ECU fuse under the dash had blown. He replaced it and I drove away, asked the accelerator for more power going uphill and it blew again. I have absolutely loads of spare fuses but I got home okay.

Today I've had a play and it seems it is drivable when you first get going so long as you don’t put your foot down too much. If you do, in a ‘low’ gear, that fuse goes. I spoke to a Bongo specialist who reckoned getting an auto electrician might be the way forward, it is there anything I could do? I understand that fuse (2nd row down, first on the left, 15Amp) is on the same circuit as the fuel pump, ECU and transmission? Any help, much appreciated, cheers!

Welcome, which engine do you have ?

The fuse you mention covers many things which will all fail if it blows, but without knowing which engine.....
15 Amp Mini fuse
Engine - Control System - WL-T
Engine - Control System Ignition - FE-E,J5-DE
Engine - Fuel Control System - FE-E, J5-DE
Engine - Cooling System - WL-T,FE-E, J5-DE
Exterior lighting - Reversing Light - WL-T, FE-E, J5-DE
Chassis related - EC-AT Control System - FE-E, J5-DE
Chassis related - 4 Wheel Anti Lock Brake System (4Wabs) - WL-T, FE-E, J5-DE
Body - SRS Air Bag System - WL-T, FE-E, J5-DE
Others - Diagnosis Connector - WL-T,FE-E,J5-DE

Hiya Thanks for the reply. It's the 2.5 Diesel Engine

The 2.5 TD engine is the WL-T engine so all those circuits above that have the WL-T listed against it are possible causes of the problem, its normally the wiring itself that is the cause but can be something on the end as well of course!

That is very much appreciated, thank you. That'll give us plenty to go on and get started with!

Best regards

Hi
I just wondered if you ever found the solution to this? I'm having similar problems and am completely stuck as where to begin. My mechanic said he would have a look but only if I can provide a bit more info.
Thank you
