I had the same problem once, check the following:
you might have a shorted injector
You might have a faulty ECM as a result of a short in the wires that come from the ECm and connect to the injectors.
Your best bet is to check all the wires first to see if you have a short in the wires, then check the injectors and last look for an ECU - ECM
I hope this helps.
