SOURCE: Runing high rpm while in idle

The concern happened after you relaced the plugs? You need to look for a vacuum leak that may have been created during the install.

Hold gas pedal down start car


If this has a carburetor, look at the Power valve that is connected to the throttle lever. It is a small plate in front of the carb with a lever that moves with the throttle. There is a small rubber valve inside which allows gas to flow between chambers.

Another possibility is the fuel pump. After that, a bad Vacuum leak like from a ruptured EGR diaphragm can cause these problems.

93 saturn wont start unless you hold dowm gas pedal


Have you tried cycling the key a few(3-5) times, before cranking(and trying to start it?
What i mean is turn your key on, then off, and on, then off(3-5 times), and then turn the key back on, and try to crank/start the vehicle, See what that does!

If that works then you have a fuel leak somewhere.

if that DOES'NT work, fuel is leaking into your engine while it sits
(more than likely bad fuel injectors!)

I have a 1995 Buick Regal with a 3.8 V6. Car will start just fine on a cold start but will not continue to run unless you hold the engine on at least 3000 rpms for about 30 seconds. it will then idle just...


i think you might be right it sounds like your engine is getting over fed fuel you are probably not getting very good fuel mileage either the 3.8 and 5.0 would defintely require the same volume of fuel it is probably playing havoc on the pressure regulators i would get another fuel pump and start there

its not getting enough fuel to engine. it could be a plugged fuel filter, low fuel pump pressure, or a bad pressure regulator. check the fuel filter first and then go from there. also be sure plugs and wires are ok.

theres a couple things it could be 1. you could have low fuel line pressure which means fuel pump could be bad or a ground wire that runs to your fuel pump or your fuel pump regulator could be bad

1998 jaquar vanden plas won't start


The early V8s were bad to flood out. Try holding foot all the way down to floor when cranking.(This tells on board computer to shut off fuel while cranking) Crank like this for at least 45 seconds. Repeat this two or three times. The next time, while cranking, take your foot off the pedal for just a second, then back to the floor. These gives it just a little bit of fuel. Do this for five minutes or so. If it is flooded, you will hear that the longer you do this, the more the car sounds like it will run. If it catches, hold gas pedal half way down while running. This will clear the raw gas out of the system. If this doesnt work, in the trunk fuse box(take cover off) is a row of relays(brown 1 inch squares) in a "T" configuration beside fuses. Tap on them or swap them around. They are bad to stick. The second relay down in the center of the T should be the fuel pump relay. If these suggestions don't work, I would advise calling the dealer. But these are the most common faults. Good luck!

99 fire bird wont start


Sounds like the fuel pump is bad. You need to test fuel pressure. I can tell you the fuel pressure spec, but what year is it 89 or 99? And what engine?
