Okay so the car won't start unless I hit it with starter fluid, once it starts it starts and runs. Im getting 12 volts in the power wires for the injectors, should there be that much power going to them? Also the maf is only reading 3 volts at wot at 7,000 rpms in nuetral is that right?

The white power wires for the injectors are fed by a blk/red wire directly off the ignition switch. Not sure what pulling the intake piping off has to do with it, that shouldn't change anything at idle to make it not run. Is this a new problem or since the engine was installed?

It just started to happen after I swapped out the maf to a Z32. I did a diagnostic on the ECU and I got two codes one said there was a problem with the maf circuit and the other was the tps sensor. Is there a way to bypass the ignition switch and run a direct wire 2 the injectors?

Okay so I wasn't getting any power to the injectors at all. So I ran a wire directly off the positive side of the battery to the one solid white wire that goes into the resistor pack. Car will start now but I have 12 volts to the injectors..not good since they are low impendece. Am I correct one single wire comes off the ecu then goes into the resistor pack, and then 4 wires come out of the resistor pack and go 2 the injectors?

Is is possible that the resistor pack is bad and the 12 volt current is just passing straight through?
