S13 sr when I go to start it, it turns on revs to about 1500 and then dies and it does it a few time then I'm able to use the gas to to keep it on and eventually it will ideal on it's own. I've also noticed my afr is off running more lean and when it bounces off rev limit it's very slow even in 1st gear any thoughts??

check timing,tps

Ok I've also been having problems with my ecu but I don't think that's a problem cuz the car does run and drive almost normal beside the afrs being off

Could it be my fuel pump, the car came with a r33 or r32 pump but not too sure, it's really loud even louder then a wallbro

I had a bad MAF that caused all kinds of crazy problems like that.

Well I checked my timing, tps, grounds and changed my fuel pump and still same shit so I've been having alot of problems with my ecu so I just bought a power dc d-jetro so if it's the maf I'm using the map sensor so itwont matter any more

Sounds like a bad Maf, nice pick up on the power fc I can never find one with a map sensor

If the maf was bad would it still make a difference if u disconnect it?? And wouldn't there be a engine code?? I bought the power fc from frsports I hope it comes with the map sensor lol now u have me nervous
