We've been having the same problem with our 1999 Tahoe. We were also told either fuel pump, fuel regulator, or injector. We believe it is the fuel injectors, particularly since reading this:

I have a ed v8 won't start been sitting for two years put new fuel ,, new fuel pump new injectors ,, got spark got fuel pressure won't fire unless u spray fuel in the throttle body


This is fairly normal for cars left standing for lengthy periods, u can start most vehicles by spraying fuel directly into carb, or a great product called Bradex in the air intake, this is an ether in a can, once the engine starts it should run, but some vehicles that r started this way to often, get to start only this way, it sounds like despite new pump, the fuel is draining back over night & not there for starting in the morning, check ur fuel lines I bet its 1 of them causing the drain back, fit a 1 way valve as close to the carb/injector system as possible

I have a chevy colbalt 2006 ls .it is fuel injected. i ran out of gas and now it will not start even after making sure fuel tank is full ......


It probably needs a little priming. In order to do such priming, I would turn the key on for about 20 seconds, until the fuel pump goes off. Then, turn it off, do it again. Do it twice more, and it should be primed. Just to make sure, spray some ether down the air intake, and try and fire it off.

Start out by spraying a small amount of starting ether down the air cleaner. If it cranks and runs for just a few seconds at least, you probably have a fuel problem. Turn the key to "On" and listen: Do you hear a whirring noise, the fuel pump kicking in? If you do, then you need to replace your fuel filter. If not, you may have to replace the fuel pump. If the engine does not start up after the ether, you might check the distributor, make sure all the wires are plugged in. If they are, The coil may have failed.

possibly a bad fuel pump, check there first. Have someone spray an ether based aerosol cleaner into air intake while starting, if car runs while spraying then your fuel pump is bad and needs to be replaced.

93 gmc jimmy wont start turns over and theres spark but it wont fire. fuel pump sounds like its priming


spray ether into intake , if it wants to run then you have a fuel problem. if you can rent a timing light, check the timing, it could have jumped, and it will still have spark. also check the plugs for proper gap.

Try replacing the fuel filter and check the fuel pressure at the shredder valve. Low fuel pressure from a week fuel pump or dirty fuel filter will cause hard starts, a bad ground will also do the same thing so check the ground wire for the fuel pump which is separate from the main wire harness to the fuel pump sending unit.

Good luck and thank you for using FIxya.

Hello. If you remove the fuel filters and fill them with fuel, then hold the accelerator pedal to the floor while cranking the engine it should start. If that does not work, spray a little starting fluid (ether) into the air intake while cranking, just use the ether sparingly. This should get you going again, good luck.

(TOYOTA SURF 1990 TURBO DIESEL) No diesel coming out of fuel pump


If it has glow plugs or an intake heater you will need to disable the circuit. Then you can use a small amount of ether to spray into the air cleaner.!!! If you spray too much and/or Dont disable the circuits you can damage the motor!!! When you spray the ether, if the engine starts and stalls then its not getting fuel. This could be related to the fuel pump, injection pump, the fuel system loosing its prime(fuel line leak), fuel shut-off valve or solenoid. If it doesn't start then it could be related to your timing, valves or maybe compression.
