Loss of power (safe mode?) - Problem with fuel pump sensor?
Posted: Thu Jun 03, 2010 6:57 pm
Have been searching round the forums and various places that you have suggested but can't really find a definitive answer so I thought I'd get in touch for a bit of bongo expertise!
I have a 2002 2.5TD 4WD Bongo Aero Tin Top
Today, driving to work the glow plug light came on and the vehicle's power dramtically dropped. I have since learnt that this is the safe mode. I took it to a friend of mine who put it on a 'launch' diagnostic check which came up with the error: P1189 - Fuel pump speed sensor/wiring. He turned off the trouble code but when I started driving it came on again after fives minutes. Interestingly when I stop the vehicle and leave it for a bit the light turns off and it's alright to drive...for about five minutes again!
I took my van to a Japanese parts dealer to get a replacement sensor. I explained the problem and he looked at the Fuel Pump and said that because it was a newer model of Bongo he didn't think much could be done to fix the pump (change sensor etc...) and that I would need a complete new pump which obviously would be at a great cost.
On the recommendation of a friend (also a bongo owner) I took it to a couple of Auto Electricians and explained the problem and showed them the diagnostic print out. Both of them suggested that they would need to run their own diagnostic as they thought the 'launch' system was unreliable. If it showed the same fault they would then test the pump, and test the sensor and then the connection from the sensor to the ECU and then look at fixing it. One also referred me to a company that specializes in fuel injection.
I'm not sure if any of them have had any experience with Bongos before and my head is a bit frazzled with all the mechanical talk. All I can see for myself is that I've been told different things and it all seems a bit speculative and looks like it could cost a lot of money. Is it true that I would have to replace the whole fuel pump? Could it be that what has actually gone wrong is somewhat simpler and cheaper to fix?
I was just after a bit of advise with what avenue to take. Maybe you have seen Bongo's with similar problems. Don't really want to rush into it and end up having to pay hundreds if I didn't really need to.
Many Thanks in advance,
Dan
