If you checked the EFI fuse and it was good, the ECM probably is getting power, assuming there is power to that point already.
I can see a few scenarios here. and a few things left you should try, or have a mechanic try.
Meter out the coil to rule that out. If it's out of spec, your truck won't start. It's the box that the 7th ignition wires goes to. Trace it from the middle of your distributor cap, over to the black box sort of down and in front of the master brake cylinder (going on memory here). That box is your ignition coil. Measure the "primary resistance" between the two terminals + and -, and then the "secondary resistance" between the + terminal and the coil wire ouput. I don't know what Toyota's specs are for the coil, so you will need to call a dealer and ask them, or reference the FSM. Your coil readings should be close to spec. Do you know how to use an ohmmeter? That's the measuring tool you'll need.
Second thing, if it were me, I'd measure the fusible links, instead of relying on pulling them to determine whther or not they're good. Yeah, they probably are, but still, just to be 100% sure...
Third, you might have a dead ECM. I doubt it though. But it is a possibility.
Fourth, maybe your wiring harness got toasted somewhere by the EGR pipe. Our trucks do have that issue in North America, where we run an EGR system. You're probably going to need to have a knowledgeable mechanic to check that out if you want to perform continuity tests on the wiring. You could do a visual inspection however. Search on the topic to hopefully find some pictures of where the EGR pipe is, and where the wiring harness intersects it at. It's on the driver's side firewall, the EGR valve (the one closest to the fender) and the VSV valve that control it (the one more toward the middle of the engine bay) being the two saucer shaped things, and then the EGR pipe you can see going from the EGR valve down towards under the truck. You should see where the wring harness is right by it for a section of length.
Also, I've read that the wiring harness can sometimes short out against the sheet metal somewhere by the passenger's side firewall, where it goes into the cabin. You'll have to search more for info on that, not too familiar with it.
I think, personally, it has something to do with the doofuses at Jiffy Lube, since your truck was fine until they messed with it. It would stand to reason, IMO. I'm wondering if the wiring to your MAF got screwed up and shorted when they replaced the air filter.
