engine fails to start up sometimes, 2017 Mitsubishi Eclipse Cross after few hours starts up normally Fuel Pump

Car was brought brand new, first time happened after running for over 2 years,
1.Road assist jump-start solved the problem. mechanics couldn't find any faults nothing showing in the computer. Replaced the battery.
2.Happened again while stopped at the airport for a pickup jump start again started the engine.
3.Third time happened RACV mechanic could,t get it started. Had to tow it to mechanic. next morning Mechanic said no fault in the car it started normally. Could,t detect any fault.
4.Happened again and after waiting for nearly one hour it started normally.
5.Happened again let the engine rest for nearly one hour and tried but nothing happened. Road side assist could not get it started Had to leave the vehicle parked at the road side and leave as all the near by mechanics closed. Next day car started normally so drove it back.
6.Yesterday evening drove it home and stopped in the garage wanted to go for dinner out it did not start, took a uber and once I came back home started normally

The Mechanic think it may be the fuel pump and wants to replace it but he is not 100% sure just a guess work
Has some one experienced this problem before
Car runs normally but occasionally fails to start. But starts again after somtime
What could be the problem ? Can it be a relay or a sensor?

Hi there,

That is understandably frustrating experiencing intermittent "failure to start" issue on your car. Here are top four possible causes of that problem:

1. Wiring issues. A loose or partially connected wiring could cause the intermittent "failure to start issue." Please check the wiring system of the battery to alternator (and starter) for loose or rusty portions which may affect or impede electrical flow.

2. Faulty starter motor or solenoid. If the starter or solenoid is bad, it will not engaged properly at a given time.

3. Ignition system issue. A defective spark plug or an ignition coil will disrupt spark needed for engine ignition.

4. Fuel system issue. A bad fuel pump or clogged fuel filter can cause "intermittent no-start issues."

I hope this helps!

Fuel Pump

Dealing with a bad fuel pump can be stressful. You may get issues like hard starting, poor fuel economy, and loss of power and acceleration when it starts to fail. Don’t wait until you’re stranded on the highway before you replace your bad fuel pump.
