My '87 1.3L (JA) Samarai was very difficult to start when cold, but started and ran fine when warm. I wasn't sure that the fuel filter (mechanical) was the problem, but it was 23 years old so I replaced it with a new one. Now it won't start or run at all. Before replacing the new pump, I cleaned the mating surface, used a new gasket, and turned the engine to move the pump rod back into the head housing as far as possible. The new pump mated snug and I tighted the bolts and ensured that the inlet, return, and outflow lines were correctly connected and clamped. When the starter turns the engine over, I see no fuel flow from the pump outflow port. I didn't check the fuel filter, but it was working ok before the pump was changed. Anyone have ideas on this problem ? Of course, the new pump might be bad, but I'm thinking it might be more probable that I've overlooked something.
