Check the EFI fuse, Ignition fuse and the EFI main relay then comeback for more help. Its right on the bottom of the J/B cover identifying the relays and fuses.
Coil has power do you mean the positive terminal of the coil-disconnect the coil wire at the distributor, have someone crank it over, ground it and check for spark.
Find the check connector under the driver seat put a test lite on the battery terminal tell me if you have power there.
At J/B- when you turn key On, the EFI relay should click-do you have this?
Also stick the test lite at the EFI fuse both contact- test lite should lit.

Suggested Repair
Check the EFI and ignition fuses, EFI main relay, coil spark while cranking, and power at the check connector. On the 2TZ-FZE, test the crankshaft position sensor on the left front of the engine. The original no-spark issue was fixed by replacing the EFI relay and a bad computer.
Conversation Summary
A 1995 Toyota Previa had no spark despite power at the coil and good fuses. The expert advised checking the EFI and ignition fuses, EFI main relay, coil spark, and related power. Replacing the EFI relay and a bad computer fixed it. A later Previa with a supercharged 2TZ-FZE had no spark on cylinders 1 and 2, and the expert recommended testing the crankshaft position sensor.
