Thank you for these videos!!! Quick question if you have the time: Toyota 8FGU30. Intermittent crank but no start. If spark checks out fine, I am thinking regulator. I will drain it and see if oil comes out. If I see a lot of oil, I should replace the regulator ??? I heard we shouldn't overhaul them, not worth the time. Any advice would help.
@@forkliftgeek10 Thank you for your response, greatly appreciated. I think I have a fuel problem though. Is regulator replacement common on these 8 series Toyotas ???
@@justinlang5481 I would not say common but they do go over time.. You might want to check the lock off first to make sure fuel is reaching the regulator.
Yes. But it could also be wiring to the throttle motor or the throttle motor it self. They would have the same effect. As long as the throttle is not able to open. You would also want to check that the rpm signal from the distributor is reaching the ecm.
@@forkliftgeek10 thanks for answering in my case take time to star cranking cranking star but no throttle at all you push the pedal nothing and after a couple minutes throttle good and unit runs fine any advice
It is still possible that it is the throttle motor starting to go. But, I would check also the signal from the distributor. The ecm needs this signal to know that the engine is cranking to open the throttle plate.
That is the whole point of the video to make sure that when doing a compression test make sure that the throttle plate is open. To maximize the air coming in. What poor understanding.. 😆
As a heavy equipment tech I would have not guessed to make sure the throttle is opened up, not a thing when working with diesels. I'm very glad I've seen this as I do run into forklift/LPG engine repair jobs from time to time and if I come across a compression test scenario, I WILL make sure the throttle plate is open so I do a proper test like you've shown. Awesome vid

Thanks for you time, nice tips! now is time to perform a good diagnostic...
Nice one. Good job.

Just because you see oil come out does not mean the regulator is faulty. Spray brake clean into the air eaner box while cranking and see if it starts.

@@forkliftgeek10 Okay. Thanks bro for your response. Greatly appreciated!!!!
Your the best I have the same problem what you replace the ecu??

Throttle plate does not control intake air the idle speed controller does. Please put a mechanic on that knows what the hell they’re talking about
You would be partially right if there was a separate idle air control, but there isn't. Lol.
A compression test is always done at full throttle. You did the compression test wrong! What a piss poor mechanic

He is a very good mechanic .
