Corolla NZE. It runs for a few secs when starting then shuts off. What's wrong?


Could be that your fuel pump is going bad? Have the fuel pump pressure checked, the average fuel pump pressure is around 40 to 45 PSI, anything less and the car will stall or stop.

Engine runs 15 or so will shut off and starts when cool. Replaced fuelfilter and fuel pump relay. still does the same thing.


If you don't have any check engine warning light on your dashboard relating to EGR system means it has to be the FUEL PUMP according to you fuel pump relay and fuel filter was replaced but the most common cause by that is fuel pump...to verify have you try to install Fuel Pressure Tester to a fuel line it might not be the specified psi while observing the tester a several minutes tester shows it dropping down the pressure till it shut off by itself.

Fuel Pump problems. Diagnostics shows a pressure loss.


pressure loss is either a bad fuel pressure regulator on the fuel rail where the injectors are, or a bad check valve in the fuel pump in the tank. usually the latter.

A quick test is to turn the key to on and measure pressure. Should be 40 psi. Pump will hum for 5 seconds and shut off if engine is not running. (Safety step).

Pressure should drop very little for 5 minutes.
You can cycle the key off for 15 seconds or until you hear the relay click off. Then turn key back on to start pump for 5 seconds again to build pressure. This will help get it started for the day as it builds pressure that bled down over night.

Please rate, thanks.

1999 hard starting expedition, with 5.4 engine


fuel pump may be going. try this. turn key on, listen for fuel pump to run for 5 seconds. Turn key off, wait 15 seconds or until you hear relay click inside car. Turn key on again for 5 seconds and ff for 15 seconds. repeat once more. This will pressurize fuel system to 40 psi so injectors have full pressure. If it starts quickly now, you are getting bleed down through the check valve in the fuel pump or the fuel pressure regulator on the fuel rail.

1997 tahoe wont start


it is not the regulator if it has 40 lbs of pressure try to pinch off the return line and if pressure drops quickly it is either the check valve in the pump or the rubber seal between the pump and the sending unit

Fuel problem


fuel pump could be overheating and need replaced, if this happens exactly the same each time it seems that is the case, the gasoline in the tank cools the pump through the returned system, alot of people that drive around near empty all the time will burn out their fuel tank quicker because of the pump not being cooled properly, you have spark when the car wont start?
