Hey guys, me car's kicked the bucket. Drove into town to get food, parked up, come out 10 mins later, and she didnt want to start. Checked all the fuses, and theyre all good. She kicks over, but dribbles for 1 second then dies, then refuses to start again. Thought it might be out of fuel, even tho the fuel level says its got half a tank. Put 5L of fuel in it, and she starts and runs for about 3 seconds then dies, and will do that everytime you try to start her. Checked the fuel line, and it has fuel then just cuts. Put the ignition on, and listen at the fuel filler for the fuel pump, and nothing, no sound. It's has an issue where, when i put my foot down when it has half a tank of fuel or less, it jerks and coughs, but when the tank is half and above, she runs perfectly fine.
I think the fuel pump has kicked the bucket, or there's crap in the filter.
Any ideas? anything else it could be? I just want to know, where in the tank is the fuel pump, how do i get it out, and what type of fuel pump does it use, just so i can get her back on the road. Lucky i am walking distance to work.

Search for fuel pump Ecu bypass .
Try this before changing the Pump .
Remove back seat . The bottom lifts up at front and tilts out leaving 3 bolts ( 10 or 12 mm from memory ) . Undo the 3 boots holding in the top section of seat , lift it up then out .
There is a round panel , use flat screwdriver to pry off . This will leave you with 6 or 8 ( cAnt remember ) screws / bolts . Undo these to see inside tank ( make sure windows are down and good ventilation ) .
Then 3 bolts and 1 hose holding hanger in .
There might be a more detailed write up if you search I'm not sure .
First though , fuel pump Ecu bypass trick before anything else

Ill have to do it tomorrow after work, ill do that before i buy anything. To do this bypass, does it matter if i have quite alot of fuel in the tank? its one bar above half, i dont want to open it and have fuel spill inside the car...

Enzo re-read Daniels reply carefully. What he says is search for fuel pump Ecu bypass. Try this before changing the pump. Do the search. It's well documented. It involves putting an electrical link into the connector under the bonnet.

Yay! Hahaha it's the fuel pump ecu guys, done the bypass and she's all good. New fp ecu I need then. Is it ok to run it like this until I get a new FP ECU? Will it flood my engine?
Started her this morning, idles a bit low and a slight knock that went away when she warmed up. Anyone?

Yeah you can use it with FP and B bridged, but be aware that it's not a great situation to be in, if you crash - the fuel pump ecu shuts down and stops fuel being pumped into the engine - which is kinda nice not having fuel being sprayed everywhere.
Also, the little paper clip that you're using bridges FP & B gets very very hot. I'd not want this under my bonnet for extended periods of time. Just get a second hand FP ECU and replace it, very easy job.

ive been running mine bridge for the past 6 months. a paperclip gets hot because it cannot efficiantly tranfer the power. its a good temp fix but if you make a proper jumper cable from old plug pins and 2mm insulated wire it works fine and doesnt get hot. as james said though, if you crash your car the pump will keep running if the engine is stalled though. i actually think there is a type of relay you can make that does the trick though as it uses the ecu power wire to switch on and off. i found it on the internet somewhere once in the past.

probably melt. have a look for an old broken applaiance like a tc or a fan and use the wire from the power cable of that. you want about 10-12 guage wire to conduct upto about 25 amps. (alittle overkill but better to be safe than sorry)

I used the Red wire from a turbo timer, it didn't specify how many gauge it was, but its thick enough. The wire i had it in was fine, didn't melt and it wasn't hot, but it was quite thin so yeah. Time to put up post for FP ECU in WTB section..

I 100% agree with dan. Leave it bridged and save up till u can get a new one as you r likely to have the same issue again in 6 months because the secondhand one you get will still be 20 years old

Search for the part no on thins forum, It's listed dozens of times, then plug it into www.amayama.com for a price.
That's ex Japan so a few weeks wait, otherwise try your local Toyota dealer or Castle Hill Toyota in Sydney have been good to Imports. Price will be higher locally, though.
