Car won't stay running. Assistance please...

Hi there guys. I have a stock sr20det in my 93 240sx running off a Power FC that won't stay running. It starts right up, but then dies right away. The car was running fine with this setup before I upgraded my turbo (T25 -> T28) and MAF (stock -> 300zx) over the winter. I have 2 main concerns right now.

1. After the installation I noticed that the CAS was missing the bolts that hold it in place. I don't remember removing these bolts but nevertheless they were gone. I replaced them, but I'm wondering if the change in positioning of the cas would cause the engine to not stay running.

2. I am also wondering if my MAF is bad. According to the PowerFC, it is seeing a 500 or so mV signal from it. But this was the only electrical thing I changed.

Any thoughts would greatly be appreciated. I spent Sunday afternoon doing some searching on here but I just wanted some input on my particular situation.

Thanks.

if you didn't have the bolts in place on the CAS when you were starting it, it might have missaligned it self. Have you pulled the cam cover off and ligned up the CAS to the marks on your timing chain?

I have not. I was hoping I wouldn't have to do that, but I guess I'll do what I gotta do. I'll give that a shot when I have some time this week. Thanks,
