Starting Problems on Diesel Bongo (2000)

Post by Ian » Thu Apr 29, 2021 1:38 pm

This query has been received from a garage on the Isle of Wight. Can anyone help?

I hope you can help with a fault I have on a 2000 Mazda Bongo 2.5 Diesel. The vehicle was recovered to us with a suspected blown turbo as it was revving up on its own (that's what the AA said). Removal of the turbo showed nothing obvious so the cylinder head was removed. Oil had been leaking from the front corner so it was skimmed and refitted. However now it will crank but not fire.

There is fuel up to the pump but nothing coming out at the injectors. Spraying a small amount of easy start will make the engine try to start but then it stops. I have some 12V feeds to the plugs that go to the fuel pump but don't know if they are correct as I cant find wiring diagrams for this vehicle.

My other concern is being unable to flash code read it. I have linked pin C (TEN) and pin E (GND) with a jumper wire and pin D (B+) and pin A (FEN) with a led but do not get any flashing pulse at all as I want to see if there are codes for crankshaft sensor or camshaft sensor. I have tested pin D to confirm there is a live feed.

I was wandering what you thought about this.

If nothing is coming out of the injectors then either the pump isn't being turned or something is blocking the fuel coming thru the pump itself ? Can someone provide a spare pump perhaps to try out ?

Check the stop solenoid on top[ of the pump.

Cheers Rita. I got an email from Allan (in Plymouth) pointing us in the same direction. Can you or anyone point us to the correct Lush page and drawing number?

Cheers Geoff. It's actually a 2000 model so different pump, but same part number

Fily-by-wire. Also consider fuel control unit inside pump.
It's a pity the garage can't get it scanned. Takes away some of the guesswork.
