I had same prob m8

What i did was bridge the fuel pump relay plug so the pump is going all the time then gently push down on the mfi flag and fuel should start to come out of the injectors.
If you just take a injector out and turn the ignition on so the pump starts up this wont work as there is now a air leak.

Hope this helps
pete

Volt drop the fuel pump to see what it is doing. It could be a blockage before the pump that is preventing enough fuel getting through.

The pump should be zero volts both sides when volt dropping. What exactly did you do?


Do an amps draw test as well.

im not too sure what volt dropping is, but i juts tested the voltage across the connectors when cranking and when not. i think when cranking it went down even more...
