Hello Psullivan and welcome to Just answer.com, Super mechanic here. You will have to see if there is power at the 15amp trans fuse. If not then I would say to check the fusable link at the starter, or back of the alternator. Here is a diagram of the injector circut. You might want to run power to make sure that the injectors are going to pulse, so that you know the ECM is good.

The fuse link at the starter could have very well burnt out. If you pull on the wires you will feel one stretch if it is bad, but I would check it with a test light to make sure.
