The car does not start unless I spray fuel into the air intake. Then it starts and runs. The main relay checks out. But when I check the power to the fuel pump it is there. The manual says to replace the pump. But the pump works when I sprayed fuel in. Is the manual right?

If the car runs after it starts, then the fuel pump should be OK. Does this happen when the engine is cold/warm? You could have a problem with the fuel pressure leaking down, which may be from a bad check valve, which is located on the pump, but this will normally cause a no start when the engine is warmed up.

no, the relay may work but did you take it out the black box and check the circuit board. because of the change in temp the solder joints rise of the circuit board i had the excact problem when and brought everything from starters to alternators fuel pumps distributors new plgs and wires nothing work. when i fixed the back side of my relay it worked like a charm.... or just by a new relay.
