How to troubleshoot a no fuel problem, no fuel at fuel rail in a 2000 olds sillhouette.

First check there is battery voltage to the pump and the pump starts when the ignition is switched on , if not check fuse and relay, check wiring from relay to pump. If ok and the pump is working , check for fuel blockage from the tank inlet to the pump , some have a sock type filter in the tank pick up tube, if all ok remove the fuel filter , switch on and fuel should flow at the filter, fit a new filter, if still no fuel at the rail fit a fuel pressure gauge an check for low pressure , if ok, the fuel pressure regulator may be stuck causing a air lock replace it.

My 03 Nissan Altima wont get over 2500 rpms

first check your fuel system, replace fuel filter, also check your fuel pressure regulator on your fuel rail it may be leaking internally if ok check your fuel pump operation. if your fuel system is ok then check for a restricted catalytic converter its a common fault I encounter with them. if that to checks out ok then have the ecm scanned by a shop or the dealer could be a faulty engine speed sensor or crank or cam sensor

1996 Silverado 5.7 Won't start . I replaced the fuel pump and it is getting fuelto the rail but won't inject. If I prime it at the throttlebody it will start.What could be the proble?

Verify the fuel pressure is 60-66 psi at the fuel rail. Fuel pressure regulator could be the problem.

Car wont start

My routine to check non-starting motors: (petrol/gas models)

  • Check immobilizer status
  • Check fuel supply -does it reach the fuel rail when starting. If not OK, check 12v supply to fuel pump when starting. If OK, fuel pump maybe dead.If not present, check fuel pump fuse and relay.
  • If fuel supply is OK, check spark ignition. If not OK, follow the supply circuit backwards to the ECM. Coils and/or ignition amplifier connector should have one 12v supply to it when ignition switch is on.
For Diesels with 'common rails' you can take same approach for fuel. No ignition testing possible. The diesel fuel pump still needs battery power. It will make some sound when IGN is on. If not, check ALL fuses and relays.

Chevy tahoe 1999 now it starts but runs for a few seconds then i wait it starts and run for a few seconds again

Seem's like your fuel pump isn't able to keep the good fuel pressure.

Might be a good idea to check your fuel rail pressure. I assume that it drops before your engine dies!!!

If fuel pressure is ok in your rail, try cleaning the fuel rail and injectors. Sometimes dirt can go from a trashed fuel filter an clog yor rail or the injectors.

Have a international dt530 that turns over but will not start. have replaced inj's, fuel pump, fuel tube sleeves,pressure regulator on back of fuel rail, getting 980 lbs at huei pump, has a little blowby...

for common rails or any injectors to work properly the pressure has to be around the 22,000 psi mark
check the fuel control module for operation and or check the pressure regulator for the common rail

When I drive along it's all fine, but when I put my foot down the car starts to skip like its short of fuel.

Do not do anything if it is a common rail diesel without more instruction. Common rail can be very dangerous & the following instructions are not for common rail. Probably is short of fuel. When was the fuel filter last replaced & the sediment trap drained. A lot of diesels also have a lint filter (fine mesh) located in the pump where the fuel line goes out of the filter into the pump. You just remove & blow out with compressed air. Do you know how to prime & bleed the system. Did the problem start just after haveing a fuel filter fitted?

if you have the same problem with the engine Hot or Cold then it may be the cold start fuel injector in the throttle body / carb. may need to be cleaned or replaced.

if it starts using ether, it suggests a clogged fuel filter. You need to know what the true psi value is across the fuel rail. you can rent kit from major auto parts stores. be it remembered that many cars nowfays have 2 fuel filters- one in tank and one on frame or firewall. a quick check is back pump air through your fuel line till you hear bubbling. recheck fuel pressure and note diffetence. if it goes up you probably icked up larger debris on the screen.

It won't stay running

meassure the fuel pressure or have some one do it it should be at least 35 psi of pressure if lower by 10 psi or more replace fuel pump. if pressure ok disconect map sensor or maf sensor it will have only one of these sensors. and id gets better repalce semnsor
