DId you try a voltage reading at the yellow/blk wire at the PGM-FI relay by chance? If so, how was the voltage there?
In the circuit, the PGM-FI relay enables the injectors to pulse. You need to test for voltage there, which will also be a yellow/blk wire. Voltage can only be shunted to the injectors from the immobilizer receiver unit, after the car is started.
By any chance does this car have an aftermarket remote start system installed, or a security system?
