Help needed- 4runner not starting

[MorgzMods]

yeah, this one is definitely fucked haha. I can't hear any chain rattling, and it used to feel like it was seizing upon cold starts. but after I drained 3L of oil out and have filled it with HPR30 she seems to be running great.
I'll even cut n polish it tonight for behaving so well

In the manual for the car it mentions pumping grease into the uni? joints with NGLI#2. I assume this hasn't ever been done since it was bought new. Should I try and clear out the old shit and gunk? or just pump new grease in through the nipples?

Just pump new grease in until it comes out the cups- the correct way is till it comes out of all 4 but that's just a fuc around

Haven't yet pumped in the grease, waiting on more work and money hopefully.

Took the new starter motor back for a replacement, it's been sent off but in the mean time the old starter motor is giving me grief - there's probably sand and gunk in there from when I took it up to rainbow. I'd rather not pull it out and clean it again. Much rather put in the new one when I get it. Bit of a pain in the ass D;
