The gas heater has a timer system that will kick to power to the heater if you don't get ignition when you turn the heater on. The red lever is the reset for this system.

Yes....the first on the left is the power relay for the fuel injection system. The black one as Wildthings and Albert noted is for resetting the heater (most specifically power to the fuel pump), the third one....large silver....is the combination heater relay that controls switching for power for the blower, fuel pump glow plug system. The small one on the right is for rear window defrost.

I had almost forgotten about the black reset relay. It is controlled partly from the thermocouple probe next to the main blower fan in the heater unit. If the thermocouple does not sense heat in a set amount if time...it assumes you have a fuel leak and trips the reset button on the black relay.

What happens is that if you have not used your heater for a while the fule in the line evaporates. It can take several minutes of pumping to get the line full again. If its been months....it cna take up to 2 cycles of pumping and switch restting to get flame in the chamber. Ray

No....these relays are for the gasoline HEATER system only and have no connection to the fuel injection or engine.

You need to make a full description of what the problem is with your car, what equipment it has and what you have done to it if you want us to help you.
