Fuel Pump Issues?

Hey all! I've been working on my grandpas 2001 Prerunner and replaced the oil pan. However it's having some issues starting and I think it might be a fuel pump issue, but I'm not 100% sure. When we turn the key, it starts up for a second, but then immediately dies. If we push in the gas pedal in that one second window, it stays alive for a bit and if we wait a bit for it to warm up, we can eventually take our foot off and it will idle just fine. While it's idling and we try and rev it, it will start to stall out. I'm thinking it's the fuel pump, but was wondering what you all think?

I think you'd have better luck getting an answer in the 1st Gen section.

Hope you get it figured out.

If you have access to a scan tool, maybe take a look at the ECT Sensor and see what is is reading. (Engine coolant temperature) Might be worth seeing what the MAF sensor is reading in Gram/S when it is running.
