You most likely fried the computer (ECM). There's a pigtail that comes off the positive (+) battery cable that feeds power directly to the ECM. You can check your fuses but the computer is probably done. HTH. -Jim

Also check the ignition module. They will go bad doing the battery thing. Also check fuses as the injector fusr couldv jsve blown ,
