No a car won't start with a bad fuel pump relay because no power will go to the fuel pump, meaning no fuel is coming into the engine. Will a Fuel Pump Relay Throw a Code? Yes, a fuel pump relay will throw a P0230 fault code but only on some cars. Depending on what's wrong with the fuel pump relay, you could also get a P0087, P0251, or P0148.
Thefuel pump will try to compensate for a bad fuel filter, placing undue pressure on the fuel pump motor causing the pump to fail prematurely. Contaminates that get past a dirty fuel filter can damage, clog or cause a fuel injector to leak, leading to all types of engine drivability problems. Unless totally failed, replacing a dirty fuel

Chryslermodels equipped with a total integrated power module or TIPM may exhibit a fuel pump relay control circuit failure. When the key is removed from the
Anotherthing you will want to check before replacing the fuse block is the fuel pump current. If the fuel pump is drawing too many amps, then it will burn out the fuel pump relay. You can do this right at the fuse block with the fuel pump relay remove. Just run a jumper across the fuel pump relay to get the pump to run and check the amp using

Thistells you that the relay is bad and needs to be replaced. This is only true, if you have done all of the 4 previous tests: The fuel pump relay's low current circuit (wire 2) is getting power . The fuel pump relay's high current circuit (wire 4) is getting power . That the fuel pump does come on and is producing the correct fuel pressure

Nofuel coming out of the fuel line further confirms a bad fuel pump. 2. Find the wire (circuit) that feeds power (12 Volts) to the fuel pump and with a multimeter in Volts DC mode, verify that 12 Volts are reaching the fuel pump when you crank the engine. CASE 2: The engine did not start, not even momentarily.
Anotherpotential cause for bad fuel pump symptoms is a faulty fuel pump relay. This relay controls the power supply to your Dakota's fuel pump, and a faulty relay may lead to: Intermittent power loss to the fuel pump. Inability to start your truck. Unpredictable pump operation, leading to stalling or rough running.
Doinga little digging on the ecoboost forums (f-150 and mustang) this seems to be a rather common issue. Consensus seems to be a bad fuel pump relay, bad sensor in the pedal, or various other fuses that could be bad or corroded.
