1st Gen Tacoma: Cranks fine but won't start or dies after starting

Checks, in order

1. Listen for the fuel pump
   Turn the key to ON and listen for a two-second hum from the tank. No sound means check the fuse, relay and then the pump.
   easy $ · under about $50
2. Check for spark
   Use a spark tester on a plug wire while someone cranks. No spark points to the ignition coil, igniter, distributor or crank position signal.
   easy $ · under about $50
3. Distributor cap, rotor and plug wires
   Look for cracks, carbon tracking and corrosion. Worn parts cause hard starting and misfires, especially in damp weather.
   easy $ · under about $50
4. Fuel pressure
   Hook a gauge to the fuel rail test port and compare against the spec in the manual. Low pressure means a weak pump, clogged filter or failing regulator.
   medium $ · under about $50
5. Crank and cam position signals
   A failed position sensor gives no spark and no injector pulse. Read for stored codes and test sensor resistance against the manual.
   medium $$ · about $50 to $500
