Re: injector circuit malfunction
It could be poor/intermittent connections with your new connectors. Or a problem with your resistor pack delete plug. Before pulling out your DVOM, I would do a quick check using a noid light or a logic probe on each injector connector one at a time. With key on there should be 12v to each connector on one pin, the other pin is grounded momentarily by the ECU while cranking/running. You might just have to tweak the connectors female pins so they make a good connections.
