Can't rev??

[silversr]

I just got done swapping in an sr20 in my 92 240, but there seems to be a problem, I cannot get it to rev,I can start it up fine but when I step on the gas it does nothing,so I went outside to turn the throttle by hand, but still nothing. I was thinking it was my z32 mafs but I don't think that would have an affect right?

Is the car properly setup to run that MAF, or did you just plug it in, close your eyes and hope it would work?
Any such situation, stock/modified, KA/SR, "can't rev" issues usually start at the MAF.

my guess is maf also. it doesnt even rev a tiny bit?

I got an Enthalpy tuned ecu to run z32 mafs and 740cc injectors.I'm using the stock z32 pigtail and matched it up to the sr's but the only thing I didn't do is ground the maf to the chasis,I heard it wasn't needed?

Sounds like you didnt plug in your TPS. Its not the MAF if it was your MAF the car would run shitty or most likely not run at all .

everything is plugged in as far as I can see, I was thinking it might be the tps but I have to wait and get a multimeter to check it out.

I've driven my car with tps plugged and unplugged, didn't make a difference.

Check the tps if it's within spec and check the maf while you're at it.
