SupraJames Posted January 12, 2009 Share Posted January 12, 2009 Ok came off the Lewes roundabout onto the A27 this evening, put my foot down, get 200m down the road, car splutters very badly and then cuts out, limps to a layby, but wont restart. Fires ok but dont seem to be getting any fuel. I am guessing my fuel pump has gone, as its over 15 years old, and had a very similar prob in an old car. Took 4 hours and very carefull recovery driver to get the car home on the back of a truck (never a sight I want to see again btw). Being a UK Car dont really want to get a new pump from Toyota as will be very pricey I guess, could I stick a Walbro in and be ok..? Have heard the UK pumps are better, but trying to source one could be tricky. Its only BPU so not exactly running mega power, just want it running again lol Thanks James Quote Link to comment Share on other sites More sharing options...
RobSheffield Posted January 12, 2009 Share Posted January 12, 2009 James, i would say get a UK pump, The Walbros are ok for a JDM bpu, but UK BPU may be pushing it too far. UK pump would be preferable, and is at least a 5 minute swap. Try Mr Whiffin or Mr Manley Quote Link to comment Share on other sites More sharing options...
DAT Inter Posted January 12, 2009 Share Posted January 12, 2009 A walbro would do the job. Did mine today, took me 25 mins. The other option is to source a genuine denso UK spec pump. I think they are plenty good for BPU. Im basing this on the fact that RX7's fit uk supra pumps for running mega hp. Tey can be had for around 120 i think and its just straight plug and play. Walbro requires some wire cutting etc. Quote Link to comment Share on other sites More sharing options...
SupraJames Posted January 12, 2009 Author Share Posted January 12, 2009 Thanks Rob and DAT, think I need to find a UK pump really. Found this on ebay, does it look any good..? Its quite cheap though lol http://cgi.ebay.com/ebaymotors/NEW-650-BHP-270-LPH-SPEC-SUPRA-FUEL-PUMP-WALBRO_W0QQcmdZViewItemQQ_trkparmsZ72Q3a1301Q7c66Q3a2Q7c65Q3a12Q7c39Q3a1Q7c240Q3a1318QQ_trksidZp3286Q2ec0Q2em14QQhashZitem150319296730QQitemZ150319296730QQptZMotorsQ5fCarQ5fTruckQ5fPartsQ5fAccessories Quote Link to comment Share on other sites More sharing options...
bondango Posted January 12, 2009 Share Posted January 12, 2009 Before jumping to the conclusion that the pump has gone, i would check the fuel pump relay. You can do a simple test to bypass it. Bridge out B+ and FP in the diagnostics port. Switch the ignition on, and you should hear the pump running from the bootwell area. Quote Link to comment Share on other sites More sharing options...
Konrad Posted January 12, 2009 Share Posted January 12, 2009 I would also advice to check fuel filter, it can be clogged completely like it had place in my Aerotop. Fuel filter is located at front wheel area on passenger side. Quote Link to comment Share on other sites More sharing options...
SupraJames Posted January 12, 2009 Author Share Posted January 12, 2009 Ahh thank you very much, would save some time, not sure if I will hear the pump running though, have some stuff in my boot lol Will try tomorrow though Edit - Fuel Filter was changed not long ago.

Wise to check the pump first, but if it is gone then the UK oem replacement would be wise. Quote Link to comment Share on other sites More sharing options...
SupraJames Posted January 12, 2009 Author Share Posted January 12, 2009 (edited) Indeed Rob, thats what I am thinking. Does mean removing a large amount of audio first though lol, could be fun Still need to source a UK pump as well.

Ok have tried this, and without stripping a huge amount of Audio from the boot, I am sure I can hear a faint noise coming from the boot, So would this suggest the fuel pump relay has gone..? If so where abouts on the car are they..? Thanks Quote Link to comment Share on other sites More sharing options...

SupraJames Posted January 12, 2009 Author Share Posted January 12, 2009 Have just under half a tank, found the 2 EFI relays, and tried changing them with the 2 below it and still wont fire. Quote Link to comment Share on other sites More sharing options...
SimonB Posted January 12, 2009 Share Posted January 12, 2009 Are you sure it's not getting fuel and that it's not a problem elsewhere - ignition for example. I'd suspect the immobiliser first if you have one. You could always check fuel is getting to the rail by disconnecting the feed from the rail and seeing if fuel is being pumped through.

SupraJames Posted January 12, 2009 Author Share Posted January 12, 2009 (edited) Well its just the way the engine spluttered, then died, am going to check the spark plugs as Matt recommended, then test the pump, it sounds like its coming on, but no idea if it is actually pumping anything. Plus please note I am not Supra expert, and things like taking the fuel line off the rail end sounds a bit scary to me lol EDIT - If there is anyone local that knows more about Supra's feel free to pop in lol, im just outside East Grinstead Edited January 12, 2009 by SupraJames (see edit history) Quote Link to comment Share on other sites More sharing options...

SupraJames Posted January 12, 2009 Author Share Posted January 12, 2009 Well just taken nearly 2 hours to push the car into the garage so I can work under cover. Have tested the relays and they are fine. Tomorrow will be testing the pump and checking the spark plugs Quote Link to comment Share on other sites More sharing options...

SupraJames Posted January 12, 2009 Author Share Posted January 12, 2009 Sorry that was very stupid of me not to see that. Will have a go at that now. Quote Link to comment Share on other sites More sharing options...
SupraJames Posted January 12, 2009 Author Share Posted January 12, 2009 Ok checked and light just flashes all the time, so no codes stored at all. Reset the ECU, tried starting the car then checked again and same no codes coming up at all. Quote Link to comment Share on other sites More sharing options...
Ian C Posted January 13, 2009 Share Posted January 13, 2009 If you bridge +B and FP in the diagnostics port in the engine bay, then key on the ignition and mobilise the electrics, you should hear a surprisingly loud rush of fuel around the engine bay - never mind the noise of the pump -Ian Quote Link to comment Share on other sites More sharing options...
SupraJames Posted January 14, 2009 Author Share Posted January 14, 2009 Ok right update time. Stripped the boot so check pump, bridged B+ and FP, iginition on, Pumps starts whirring and can hear fuel coming into the engine as Ian described above. Removed a spark plug and does not seem overly wet with fuel, but does of course smell like fuel. Removed Air Intake pipe sprayed a load of Easy Start down it, while trying to start and nothing, engine semi turns over but does not fire and start at all. So either I am not getting a spark, or the fuel is getting to the engine bay but not to the chambers. Any more ideas, as I am getting stuck not being a Supra expert.

Ian C Posted January 14, 2009 Share Posted January 14, 2009 If you have a multimeter you can unplug an injector (no6 at the back of the engine is the most accessible) and check its plug for +5v when the ignition is on and the car is mobilised. You can also check the other pin for ground continuity when someone tries to start the car - it should be grounded only when the ECU thinks the injector should be open. A multimeter's continuity test audible beep should be a good indicator of this (and you can perform the test on your own if you can attach the multimeter probes ok). If the injectors are firing, it's probably still a fuel system issue or ignition (although your plugs would stink and be wet). If they aren't grounding it's ECU or wiring. If they don't have +5v it'll be fuse, wiring, or an immobliser problem. -Ian Quote Link to comment Share on other sites More sharing options...
