1992 SR20DET won't start, fires but won't fire up. - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I have a 92 s13 with an s13 sr20det, but it won't fire up.
I bought it without a turbo so I knew it wouldn't start, now the owner said there was a missing fuse and it won't fire up after he sold the turbo.
Now, I tried everything, car gets spark and fuel just fine, but it sounds like the firing is in the wrong order..
Tomorrow I will get some fresh spark plugs cause it seems like a few might not fire up.
But this is very weird.

It cranks and you hear little popping noises and when the dump pipe was open you could see a flame sometimes.
Now that lead me to believe that it's sparking at the wrong time.

Any advice on this would be amazing!
Thanks!

Here's the Links to my Video's I posted of the cranking up.
I will post one during the day time tomorrow.

Vid one: YouTube - 1992 s13 SR20det won't start
Vid two: YouTube - 1992 wiring question <-- now this video is a question about a plug and wiring that consists of 2 white wires and 1 black one, I was wondering what that has to do with anything.
I really appreciate any help I can get on this.

Thanks,
Ivan.

could be your timing..., bad cas..
that o2 on there looks like the one that goes connected to a ka wiring harness...

here's what the 02 to a sr looks like...http://www.frsport.com/Nissan-OEM-Ox...ET_p_1117.html

Thats an SR20 harness nothing KA plugs into it

That is the OEM O2 sensor plug, you need to extend it using the a piece of the KA harness

yeah, that o2 is from my kat.
I took the turbo elbow out of it to put on the SR while I wait for the new elbow to come in, so ignore the o2.
And thanks for the link, that mystery wiring was the SR o2 wiring, thanks!

And how to I restab the cam angle sensor?
and the ignition timing is obviously wrong, how would one adjust it? by the CAS?
