Default 1990 V6 MPV Turns Over, Wont Start, has gas and spark

I checked for spark by spraying starter fluid into the intake, it would start firing briefly. So I started looking at the fuel. I checked the fuel pump, and pump relay... both appear to be okay. I also checked for fuel pressure using a gauge, I was getting 50psi between the fuel filter and the pulsation damper. The EGI relay seems to be working, I can hear it click when the ignition is turned on. I'm not sure how to check that the injectors are operating. The problem started when I got back from a weekend camping trip in the mountains. I came out to the parking lot after about 20mins to find that it wouldn't fire up. I am also wondering if the MAF sensor or Position Sensor could be the cause, but I don't know how to check these. I'm not even sure where the Position Sensor is.

Any help is greatly appreciated.
