Would the relays along the fire wall make your car stall?
The relays along the firewall will make your car engine not to start. The fuel pump relay is what turns on the fuel pump when you start your car and powers it down when you shut off the ignition. The engine control module (ECM) uses the fuel pump relay to control when the fuel pump is on. The fuel pump relay supplies electricity to power up and power down the fuel pump. Once the points burn or the coil breaks, the incoming voltage to the fuel pump is blocked and your car engine cannot start. If engine takes a long time to crank up, it probably is due to a bad fuel pump relay. Another way you can tell the fuel pump relay is bad is when you don't hear the fuel pump run for a couple of second when you turn the key in the ignition forward to start the car.
Can a fuel pump relay switch control the way a car starts and the way the fan comes on and off?
A defective fuel pump relay will cause starting problems. In fact if the relay fails the engine will not start at all. But the fuel pump relay has nothing whatsoever to do with the cooling fan.
What will a bad fuel pump relay do to your car?
Bad fuel pump relays aren't very common but i do run across them every now and then. If the relay is bad one of 2 things will happen - if the relay is "open" (unable to complete the circuit)then the fuel pump will not run and the car will fail to start. If the fuel pump is shorted (the contacts in the relay are fused together)then the fuel pump will never shut off...even if you shut the car off and the key is in your hand the fuel pump will continue to run until the battery is drained of voltage. Then the car will not start without charging the battery or "jumping" the car. About the worst thing a bad fuel pump can do to your car is cause it not to start. It could possibly ruin your battery if the battery sits discharged too long. However the odds on that are not great. Just charge the battery - change out the bad fuel pump relay and everything should be OK.
