I've owned the same car. Check that the fuel relay 'primes' the system before you start the car. When you turn the key to the on position (all you dash lights, ready to start) you should hear the fuel pump run for a second or two. If it doesn't run you can replace the relay for about $30. If the relay is not the problem, it may be a check valve within the fuel line to the engine. This valve keeps fuel from draining back to the tank when the car is sitting. That way, there is fuel close to the motor when it's time to start. The temp senor was not a bad shot, they were thinking it was bad sensor not telling the cold start injector to run. Obviously not the case. However, the injector itself may be faulty in some way. As long as the car always starts, it's one of these problems, assuming the ignition system and engine mechanicals are in running order.  good luck. JK

First from the fuel tank in side the fuel tank there is filter remove the screws on the top where the fuel gauge fitted when you remove gauge you can see fillter that is one sometimes blocked.

Next if you check fuel filter it is ok, but nissan sunny has fuel filter inside the caburator where fitted fuel pipe from the fillter clean that filler.

ather thiing is check your connections any leak or loose.
