1FZ Denso fuel injector depinning advice? (1 Viewer)

[CharlieS]

Hi all,

I'm looking for tips, tricks and other advice for depinning the Denso fuel injector connectors on the 1FZ. I sent my injectors out for service, and have a fresh set of connectors to go on in place of my 300k mile brittle ones. I see that there is a white center lock that needs to be pulled out, and I presume that there is a little plastic locking tab for each of the pins (although I can't see it with my old eyes). I have okay depinning tools but may need to customize a tool to be thin enough to bend the tab out of the way. Any advice would be greatly appreciated.

Pull the white piece out completely
The metal terminal has a tab on it that locks into the housing.
Push the terminal/wire into the housing a touch more to take pressure off the tab.
Slip a flat, thin blade de-pinning tool into the housing to disengage the tab. I think, on the side the white retainer is on.
Get the de-pinning tool in the right location they come out easy.

Apologies for going off-topic, but how are those JR Ready depinning tools? I mostly make due with dental picks, but it might be nice to have the right stuff.

Thank you. Pulling out the tab completely made a big difference. The plastic seems to have lost a lot of elasticity, and many of the tabs aren't bending, so I have destructively removed them.

Yes, they are JR Ready tools and they're pretty okay. Definitely much better than the last set I had of universal depinning tools that were super flexy and cheap. I'm frugal, but one day I really should invest in a full set of quality asian import pin tools. I only use them infrequently, so often fashion shop made tools or use picks.

On old connectors like that I take a pair of channel locks and adjust them so the jaws are parallel when clamped on h to he housing snd then crack the housing like you would walnuts.
