Fue Pump Failure.

Fuel pump on my RA has possibly failed. Went to start the car after work, started fine and was letting it warm up. After about 5 minutes the car started spluttering and then stopped. Turned ignition on and absolutely nothing from the pump and of course it wouldn't start. Had recovery guy out to pick up my car and he concurred that it was probably the pump.

Will check wiring and relay tomorrow, assuming they are ok then it will be a new pump but first a few questions.

1) Where is the fuel pump relay on my car? Checked all the handbooks and the relay cover but no indication

2) Anything else I should be checking?

3) Assuming it is the pump is it worth upgrading it now, especially in light of the cost of an OEM pump (80,000 yen according to my parts list.), and what would be a good, reasonably priced aftermarket pump?

4) Just uprating the fuel pump won't require a re-map I am assuming?

Any help will be massively appreciated. Cheers,

Wayne.

Re: Fue Pump Failure.

Had the pump go on mine a while back & the AA bloke was complaining he couldnt find anything out because its all in Japanese. Up rated pump was about 40 cheaper than standard one. Walbro 255 90 i thnk. No remap needed im sure.

Cheers Ian and thanks for the link Pete.

Looking at Walbro pumps but will have to get it shipped from UK I think as can't get them here. 85 quid incl vat seems like a very good price to me.

Re: Fue Pump Failure.

Def sounds like the Pump bud...

fitted my new one yesterday,20 mins in total,start to finish ..she now runs sweeter than she was,combined with the new boost settings to compensate,it's pulling even harder than she was ....

only thing to look out for when changing the pump is the filter in that sits in the tank,some are like large teabags and others are long thin ones,had a teabag filter in mine originally but now have the elongated one,no issue in the running...

Re: Fue Pump Failure.

Ginx Wayne we are think my Walbro have issues to buzzing noise from it just my luck
Also worth checking Wayne is take the IN pipe from the fuel filter off, this the line that brings fuel from the tank to the filter and so on have some rags handy have some one just turn the Ignition ON and you can try to turn the engine once or twice when you have this line off they should be no fuel or very little coming out of pipe if this the case its the pump just make sure you capture any fuel from the pipe if any with a rag hope it helps

Re: Fue Pump Failure.

Have you checked if there is 12v at the pump they are know to have bad connections.

Haven't brett, no. Don't have a voltage tester, and having never done it before would be unsure how to go about it. Assume it is easy to do? I know testers are pretty cheap.

Yeah very cheap and easy, you can do it without getting to the pump just use the white plug(iirc) at the cover for the pump, and it will tell you if the relay/fuses etc are ok.

First thing i did was check the out pipe (came off much easier without pliers) and virtually no fuel came out of the filter. When I changed filter earlier this year, loads of petrol came gushing out when I pulled off the pipes. 99% certain it is the pump, or lack of power to pump as Brett suggests.

Cheers Brett. Will grab myself a tester tomorrow and give it a go. Ordered a pump anyway as It'll need uprating next year for it's remap, but best to check there is power getting to the pump before I swap it out.

Thats it, it helps narrow things down as you will soon know if your looking at a electrical/immobilliser issue or mechanical pump failure.

Might be worth cleaning the IACV out first, they do clog up.
