u check for stupid shit? like the dizzy/wires coming out of alignment/loose? wait, if u have spark, then nm that one....

wouldnt hurt turning the car over once with the rail/injectors off, just to make sure u got gas spraying out (i dont need to go into how OUTRAGEOUSLY DANGEROUS this is, so please be careful)

check all your TB connections? (MAP/TPS/IACV and throttle cable)

it really just sounds like a ground or power came off for the ECU or some really important relay under the hood....

you sure you arent just out of gas?
