Thread: 2014 diesel Hilux slow starting & loosing fuel prime.

Thats why I said to check the oil level to make sure it wasnt making oil.

I would suspect losing of prime is due to the pre filter leaking too. Maybe a plastic part has been cracked or something during the injector work. Look for something unusual.

You could try to pressure the system to see if you could spot some bubbles or hear air hissing etc. It can be a pita to track down.

Very frustrating.
