Sr20det wiring/ecu

Post by s13driftertb »

what wire is the O2 sensor, so I can hook up a air flow meter... I know they are not that accurate, but I have it, and I'm NOT tunnig with it.

or does some one know where to get the service manual for the sr? I checked Zeroyon and I could not find one for the 13.

thanks.

FOERST thing i would check is to see if you have a bad coil. mark coils and switch them around in the motor. if it is still number 4. check to make sure you have power at the coil. then check continuity on the signal wire from the igniter to the coil. if all that is good get back to me and i will give you some more test.

I played the whole switch aroo game in the begining.

(This is the FOERST time I have ever started this engine. I've had it for almost 3 years but was not able to get the funds to put it in)

When I FOERST cranked it up the number 1 and 4 were not firing, I swaped 1 with 2 and 3 with 4 and then cranked her up and one started working along with 2 & 3. I could tell because the new turbo manafold turned gold from crome on 1 thru 3 but 4 hasn't changed much. At the time I got side tracked by a boost leak that turned out to be the #3 o-ring around the fuel injector. Those came in today and I hope to put them in tomorrow.

What would be the easy way to check the continuity? volt meter?

BTW thanks for the help. trying to get her up an drunning for the 24th Nashville event, and I still have to swap over full suspension, stearing rack and brakes.

yeah dvm is your best friend. if it has been sitting that long you could have caroshin on connectors. does not take much to make it happen. unplug the connectors for the coils coil harness and ignitor. make sure the pins are clean and not moving around in the connector. are you using a sr ignitor or a z32?

Q45 ignitor chip. I got the wiring diagram from HT

I thought the o-rings were going to fix my vac leak but it looks like someone bent my fuel rail. I tried bend it back but still no luck. I'm going to look around and see if I can find one cheap. The only thing is I'm running out of money to dump into this thing. :(

i will look around for the wiring of the ignitor you might be a pin off for the coils or something.
