Still trying to get my SR to run.Getting good vacuum. Good fuel pressure. Fuel lines are correct (I believe). Inlet between 3 and 4 runners. Discharge to fuel pressure regulator out the front of the fuel rail. Starting to think it may be the maf. If I try to start it with the maf connected, it may run for a few seconds, but when I disconnect maf, it will idle for minutes. Also ecu is going into fail safe and cuts revs at 2500 K. I have tried connecting a ka maf along with the sr maf, but the result is the same. Am I correct that the maf is the problem and does anyone know if I can use a Z32 maf using an apex neo? Was planning on upgrading someday, but don't have the money for a bigger turbo and Jim Wolf ecu right now. Does anyone have an SR maf or Z32 maf for sale?

Get another MAF, sounds like the issue.

Know of one for sale? Know if the Z32 will work with a neo?

I wouldn't mess with a Z32 one yet. Just make sure the stock one works before moving on.
