What makes you think its injectors because it won't start? You check the fuel heater fuse? Did you change the CPS? What's your ICP pressure? It's not usually injectors if it won't start. Has it been getting harder to start over time? How cold has it been, is your glow plugs or relay working correctly? We need more information.

What Bonanza said.
Do you have the wait to start light?
Puffs of white smoke from the exhaust when trying to start?
Does the tach needle move at all when trying to start?
Is the HPOP full? Engine oil level full?
Before you go digging deep into wiring and injectors, lets check some of the basics first. Could be a simple fix.

Glad you got it fixed. Nice when it's an easy fix and inexpensive.
