94 Ford ranger won't start
This is a 94 Ford Ranger 4 cylinder. Some time ago replaced water
pump. Started truck up after repair, it ran ruff for about 30 seconds then
stalled. Wouldn't restart.
Have replaced vacuum device on injector rail, computer, fuel pump
relay,fuel pump, and now fuel filter.
Truck turns over but doesn't fire, and I've checked both coil blocks and
they are making sparks.
