Starts up, but Will Not Run

[BlackdOutGST]

I searched and found one thread about this problem on a 98 GST I will try what they did to fix it, but thats a big age difference and I want to get some other ideas rolling in.

Just finished swapping a good 6-bolt out of a 93 GST into a 94 GST body. Nothing too crazy... Motor will start up and idle up to 1000 rpm and die everytime. My instinct tells me that it is electrical, because of its consistency. Found some plugs that were not plugged in originally after the problem arose, fixed them, but still no RUN. Checked timing, vac leaks, fuses (Not Relays Yet unsure how to test those). Any other ideas? thanks

Fuel. Check the pump and fuel filter.

Thanks for the help guys. Turned out to be bad wiring to the MAF sensor.
