Starts then stalls

my Z was running great the one day I parked for an hour, now it wonít stay running. It turns over with no problem but after 5-20seconds it stalls, Giving it gas makes it stall right away. If i prime the fuel pump and pump the gas it runs a bit longer. Iíve changed my fuel relays, and fuel filter. Next I was going to check my fuel pressure and MAF.. any other ideas?
also changed the TPS because the housing was broken.

I would start with fuel pressure first. Pull the vacuum line off the fpr and make sure there is no gas coming out of the vacuum port on the fpr.
