It would depend on the engine type, petrol or Diesel. Essentially for an engine to work, you need two or three conditions to be met. 1)Fuel 2)Compression 3)Spark (petrol engine only). In addition to this the engine needs to be spun by the starter motor (or push start) at sufficient speed. In order to answer the question without writing pages and pages of text, more information is needed. 1)Petrol or Diesel engine 2)Battery condition and cranking speed (if cranking at-all) 3)Noise whilst cranking the engine. 4)Circumstances leading up to the failure to start.

The fuel filter on a Toyota pickup having a 22re engine is located on the left side, directly under the intake manifold. It is held on by two 12mm bolts. If you look under the truck, you will see the filter to the left of the oil filter.
There are two types of speed sensors and you can't tell until you look. One is electrical/magnetic (VSS) and one is a cable that goes directly into the instrument cluster. Here is my answer to How to replace the Speedometer Cable in a 1990 Toyota 4x4 Pickup 3.0 3VZE V6. To remove the cable you will need to unhook the e-brake assembly and seperate the speedometer cable from the e-brake at the firewall by the gas pedal. On end goes to rear of the instrument cluster and the other end attaches to a small gear at the rear of the transmission. The instrument cluster will need to be removed.
