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.

Remove the distributor cap,and have a friend crank the engine over to make sure the distributor is turning over smoothly,not a jerking motion and skipping,
SOURCE: how do i change fuel filter under intake manifold
I changed to one on my 99 Tacoma and it is a problem to get to. What I found is that I could get to the front of the filter through the wheel well. If you have a Pre-Runner you do not have to remove the tire, but if you have a standard Tacoma you will have to remove the left front wheel. This will allow you to reach the front of the filter. You can reach the rear of the filter from under the vehicle by reaching up through the space available. It is for sure not easy to get to so if you do not want to deal with it just pay someone else to do it. Horrible location for the filter.
