I don't think the igniter is the problem, it could be a bad pickup coil in the distributor, it sends an rpm signal to the computer, if this signal is lost it won't start. Did you check for diagnostic codes using a jumper wire in the check connector? Are there any diagnostic codes? Is this carbureted or EFI?

Saw your post on another thread. I have the same truck. The fuel filter is located on the rail just below the passenger door. Its an easy one to remove,...couple bolts, but access to it is a pain.

At the cost of the igniter i recommend checking your pickup coil.( The 2 wire sensor in side of your distributor. The The igniter will not allow the coil to fire with out reference form the pickup coil. Coil has primary and secondary resistances. when the primary coil powers up and then pulses off, this cause a high voltage due to magnetic degeneration. Check the coils primary and secondary resitances along with the air gap in the pickup coil, and also check the resitances on the pickup coil. If i am right your igniter will be okay.Get a good manual for you truck, It will save you money down the road.
Toyota does not have at test proseger for the ingiter.
Also check the wires in between the pickup coil and the igniter.
I hope this helped.

you should also check the crank position sensor this is what tells the ecm when to spark. this is a prox switch and when unplugged and checking ohms while cranking you should see a sqaure wave. should go from 0 ohms to infinity. when these go out you will not get any spark on any cylinder
