Question about 2007 Chevrolet Captiva 2.4

1 Answer

Chevy captiva 2.4 no fuel pressure

The car doesn't want to start. We check the fuel pump which seems to be working, however the is no pressure. My logic tells me its the fuel pump that faulty but I want to exhaust all possible causes before replacing something only to find we have replaced the incorrect part. If we put fuel into the throttle body it starts up and idles beautifully. and suggestions and advice would be appreciated.

THE FUEL PUMP IS BAD.

if your losing fuel pressure after the pump runs the drain back valve in the pump has failed.

and i doubt that you are seeing enough fuel pressure to run a vortec engine.

low fuel pressure equals a non running vortec

That eliminates the crankshaft and camshaft position sensors. Have you checked the fuel injector itself for an open winding or stuck valve plunger? There should not be a steady 12 volts to the injector--if good injector, it would be spraying fuel steadily into the throttle body. But at least the engine should try to run if poorly. Take the injector out, dry it off with air, and intermittently apply 12 volts to one terminal while grounding the other. You should hear a click from inside every time you touch 12 volts. If not, replace it. If it does, it may be plugged with debris. Try blowing through it in reverse with compressed air.

My fuel pump seems to be pumping gas but my van wont start 02 chevy venture cranks gets fire an gas but wont start


Just because it pumps gas doesn't mean it is at the exact pressure it should be? Most fuel pumps have a psi of 40 to 45 psi, your fuel pump could be pumping at 25 psi or less which is not enough to start your car even though you can see some fuel pumping out. A simple tool to check fuel pressure can be bought at any auto parts store, check the specs on the fuel pump for your 02 Chevy first to see at what pressure it works, then use the fuel pressure gauge to check it. Anything less than what the specs on your fuel pump are suppose to be and you have a bad fuel pump?

Let's say your fuel pump works at 43psi, you hook up the fuel pressure gauge and you find that it reads 25 to 30 psi, that means it's not enough fuel pressure to start your engine.

Has anyone had problems after disconnecting the factory alarm system in a 96 Chevy Blazer S 10?


you might want to check your fuel injectors as they might be going bad. AutoZone can test them for you. also check the fuel pressure at the TBI a "new" fuel pump doesn't mean it is good. ask the parts store the proper fuel pressure. also it might need the fuel filter changed.

My 2000 chevy S10 wont start I changed the battery and it ran fine for 2 days now it will turn over but won't start


Check Fuel Pressure. First turn key to on position (without starting) and listen for the fuel pump motor. If no motor sound, your fuel pump is not working. Check fuel pump fuse and relay. If fuel pump works, check for pressure at the fuel rail (schrader valve on fuel rail for pressure testing). If no pressure, or not enough, fuel filter might be clogged or fuel pressure regulator may not be working properly. IF fuel is not the problem, start checking electrical, such as ignition control and proper spark to plugs.

1988 chevy celebrity No fuel to the carberator.


without starting the engine position the key to the on position.
you can hear the fuel pump operationing for 4 to 6 seconds upon having the key on.
if not heard running check the fuel pump fuse, the fuel pump relay, and the engines oil pressure switch.
they all work the pump you see
the engine oil pressure switch runs the pump untill the engine reaches normal pressure
once the pressure is reached to the normal range the computer shuts that circuit off and turns the fuel pump relay on

the fuel pump is triggered by the engines oil pressure switch upon starting
when oil pressure reaches normal psi the relay takes over powering the fuel pump
you see know that your relay is not operating now for the pump

1987 chevy r10 won't start


Assuming it is a fuel problem I checked at the carb. to be sure no gas was being pumped through the filter located under the power steering pump then the fuse on my 87 s10 was the ECM fuse.then check for the relay to click and the had to replace the oil pressure sending unit and mine started right up..the oil pressure must be about 4 lbs for the Pump tp operate...I loosened the fuel line to ck. for fuel but thats living dangerously...a pressure guage would be on the safe side......

Check your lift pump. It is on the framerail. If that is not working check your oil pressure sensor it is behind the fuel filter. The lift pump does not get voltage if the oil pressure switch fails.
