The TPI is batch fire (firing left bank, then right bank...). If it is fuel related, it is most likely either harness or the injector itself (swap the injectors to determine). Spark should be easy enough to determine with a spark tester.
Did you have it running prior? They wont run with the distributor 180 out (dont ask me how I know)
Depending on the year, you should be able to plug in an OBD scanner, or simply ground out the MIL and read the codes.
The problems we face today can not be addressed at the same level of intelligence we were at when we created them - Albert Einstein Or with the same level of $ - Me
