Corolla & Avensis
It also doesn't pick up when you give it some throttle when it started up?
Check that injectors getting voltage, one of the wires should always have 12v when engine is on on position, the other line is controlled by ecu and goes to ground in order to fire the injector.
hmm, any blink codes when you short the diag terminals?ok so Ive got 12v on both wires for each injector
I think thats correct, do you get any blinks? If you got the right terminals it should blink once, long pause, blink again and keep repeatingno codes... unless I'm doing this wrong the guy I bought the car from said it had a distributor code but haven't been able to reproduce that
Were the wiring harness connectors connected to the injectors when you did your voltage check? If so, this would be normal. If you disconnected the wiring harness connectors from the injector when testing for voltage, only one wire in that connector should have 12v. It makes a difference regarding if the connector remains on or is removed.ok so Ive got 12v on both wires for each injector
I don't believe the fuel pump "primes" before attempting to start the engine on these models. I believe the fuel pump first turns on when the key is in the START position when trying to start the engine. Once the engine starts and the key is released to the ON position, the ECU activates the Circuit Opening Relay to maintain the fuel pump running. Only way to prime before starting (key in ON position) is to use a jumper in the diagnostic port.Have you tried allowing the pump to prime before you start the engine? This could tell you something about the pressure if fuel pump is working.
Yup, I've used starting fluid to see if an engine will start, as a way of verifying that the pump is either good or bad. In the winter months I have to cycle my key (listening for the pump relay to cycle on then off) a few times to build pressure in the fuel system before the engine will actually start. I may have to do this several times before it'll actually start depending on how cold it is outside. This is because my cold start system is broke (I think the injector died, or the temp switch for it did), and I haven't fixed it in the 12+ years I've owned the car. Note it starts just fine above 40*F. It's just a quirk I live with on that car. Sure, it can be a pain in the butt when it's -5*F out, but then the oils nice and thick then too, but it'll eventually start. I like to think of it as an "anti-theft" device.Try spraying starter fluid into the intake to see if it runs. When it does, then it’s not fuel pump.
