Sr20det running on 1 cylinder

[Sr20probs]

My sr has spark to all cylinders. It is only firing then running on 1 cylinder. Timing is good. It has a ka maf lol. Any ideas what it could be? I have yet to compression test it and I have to check the other injectors other than that I'm out of ideas. Please help

You can't time an engine running on 1 cylinder. Mechanical might be correct, ignition is not!
If you have spark, then the next thing to check is fuel! simple test include listening to the injectors, and or removing the fuel rail and watching them spray.

if you find you have fuel, you should consider passing this of to a mechanic.
the sohc ka mafs works for certain sr20's.
so a ka mafs on an sr20det is moot, without knowing make models and years.

Why did you post this twice?

I have fuel and spark

Check those other injectors and compression on all four. You can rent compression tools at nearly any parts store and it takes maybe thirty minutes. You can't expect us to diagnose your problem if you haven't done the relevant testing...

I have compression 140 in all 4

It still won't run with spark fuel and 140 psi in all cylinders on a cold block. I'm not sure what's going on at the moment. Gonna mess with the timing a little more hopefully it will run. Thanks

I ran into the same problem with mine when I first swapped mine but I wasnt getting spark in all cylinders. It turned out the ecu pinouts were wrong

I ordered a new igniter chip hopefully it's the spark not being strong enough if not I'm gonna go with the CAS or ecu other than that I have no idea. Any ideas what else it could be?
