Re: 20V 4A-GE ST - Starting issue

Alright, I got somewhere? Tested the plugs out, found that the plugs were arking to the side, great, found an issue (It appears that the new plugs i brought may have been faulty this entire time). Store was closed so couldn't get some new plugs. Took the plugs out of a corrolla, (They were a little ...

Re: 20V 4A-GE ST - Starting issue

Im back onto this today, I pulled the oil plug and let a little oil out after noticing the volume of oil on the dipstick was quite a fair way up there. After doing this, i noticed the oil was extremely thin and smelt like fuel - going to drain some more out and put some fresh oil in there just to th...

Re: 20V 4A-GE ST - Starting issue

I can't remove the mid-cover, it's locked in there behind the pully, I dont have an issue taking it apart and re-setting the timing belt, I wanted to get in behind there to look for an oil leak at some point anyway. The VVT pully re-seats back to the default position when cranking, so it is already ...

Re: 20V 4A-GE ST - Starting issue

I can't work out what I done, it changed entirely after having a play around with the TPS and timing, it actually ran fine for that moment and I haven't been able to reproduce what I done. Upon looking at the timing afterwards, i noticed I am out by a tooth, so at the moment I am battling the crank ...

Re: 20V 4A-GE ST - Starting issue

I cant re-set the TPS at the moment, but, I did unplug the TPS and the car fired instantly, ran approx 1.5k rpm for near 10 seconds before cutting out. That is the best it has run during this entire time. Could this indicate the issue? Scratch that, I tried to recreate the situation but it didn't gi...

Re: 20V 4A-GE ST - Starting issue

That's the odd thing, nothing was touched. It went from running fine one day, sitting a couple days then on t running at all.


I will check the TPS out tomorrow.

Re: 20V 4A-GE ST - Starting issue

Alright, I re-adjusted the Ign timing, while doing this, i unplugged the pulse to the injectors so the engine wasn't flooding with fuel, after this I tested the COR and the pump runs when i put the flap. After adjusting the timing I plugged the pulse back in and it fired up for maybe 5-15 seconds be...

Re: 20V 4A-GE ST - Starting issue

Ignition timing was tested on Tuesday and seemed to be spot on perfect. I tested the crank pully too after a read up on the legacy forums, from what I can tell it is fine, but I will get under there and give it another go. I will try to test that COR out today. I appreciate your help on troubleshoot...

Re: 20V 4A-GE ST - Starting issue

Geez, sounds pretty similar, but it will fire once in a while until it becomes flooded.

I will try the fuel pump relay tomorrow.

Re: 20V 4A-GE ST - Starting issue

Any idea how many ohms to earth the temp sensor wire should have?

It seems to be directly connected to earth, it seems off to me..

Re: 20V 4A-GE ST - Starting issue

---------------- Edited ---------------- Alright, im a dork. I was measuring the wrong side. I measures one of the wires at a constant 12.2v, while the second wire seems to discharge as soon as i would attempt to measure it. It attempted to fire again after letting it sit a while, without throttle, ...
