Toyota Repair Problems? Ask a Mechanic for Answers ASAP
Hello, thanks for the request
That sounds like it may the the circuit opening relay you are jumping, without the jumper in and the relay installed what does the engine do when trying to start? Can you upload a picture of the relay?
Is it a 4 cylinder or V6?
Thanks, ***** ***** a mistake reading the year model, thinking it was an 2008, the picture would be great.
So jumping the relay makes no difference?
OK, do you have a volt/ohm meter handy?
Check the EFI fuse under the hood, should be hot at all times, check the 7.5A ign fuse on the inside fuse panel with key on. Remove the EFI relay, there should be power to two of the terminals in the fuse block.
Hello, I may have to be offline for a while, if all those check out, put the relays back in, access the fuel pump through the rear seat access cover, remove the seat bottom and the metal cover, there is a blue wire and a white black one, the blue is power to the pump and the other is ground, connect a voltmeter to the blue wire and ground the the meter, when turning the key to start and while cranking there should be 12 volts reading at the blue wire, if this the case the fuel pump needs to be replaced.
All right, so we can assume that no power is getting to the fuel pump, what were the results of the tests of the EFI relay terminals and the fuse etc.?
The relay that you jumped does it have 4 prongs or 5?
Ok, that is the circuit opening relay which is activated through the EFI fuse and the EFI relay, both of those must supply a signal voltage to the C/open relay as well as a starter signal from the ECM and a couple of other signals like rpm and spark confirmation before it will let the fuel pump run, the C/Open relay is not the problem since you already tried a new one, this is why I needed to know if the voltages at the EFI fuses and the efi relay sockets are good. The crank position sensor is a possibility, is there a diagnostic code for it? Did anyone check for diagnostic codes? I didn't realize that the car was being looked at by a shop.
Ok, just let me know what the code numbers are, if any and we'll go from there, I may be offline, just post the results and I'll get back as soon as I can, thanks.
I"m back online, let me know when you have an update for me.
