Searched for this and got like 7 posts, all unrelated.
FSM doesn't mention if you are supposed to relieve fuel pressure before you do this stuff. I looked at my fuse box and there was no fuel pump relay installed where it was supposed to be next to my A/C relay.
And how much force is required to remove the injectors? Everything plastic I touch is breaking on this car.

duh, of course you relieve the fuel pressure

and removing the injectors is faily easy.

im curious, why are you removing them? are the all original, how many miles on them , etc?

i would rec new orings i think they are 7mm [cheap, any parts store with smart employee will get em for you]

How? The way I've always done it is by removing the fuse and running it until it dies, but there doesn't seem to be one in the engine compartment.

#4 was at 6k ohms. Have 180k miles, so all are original as far as I know. If you recall my vibration problem, this was the cause. Which is quite irksome, because I took it to a toyota stealer and they told me I had bad plug wires. I tested every one and they were good. They quoted $390 to change them+spark+cap+rotor. Well, that wouldn't have fixed the problem. Charged me $60 to tell me the wrong thing, and it takes 10 seconds to measure the resistance of an injector on these things. Do you suppose I should get my money back?

Well as long as the engine is COLD, and you disconnect the battery (eliminate all sources of ignition) you can just slowly loosen one of the fuel line fittings. The KEY POINT is no source of ignition, there will be a little gas sprayed around, but not much.
