When i turn the key on the fuel pump don't run why?


There should be battery voltage at the fuel pump. Check the battery voltage at the fuel pump relay to be sure that there is power coming from the battery. Check voltage at fuel pump fuse.

What would cause gas to be in the oil


On this 1999 silverado there are only a few things that would cause gas in the oil system one being a bad leaking fuel preassure regulator or a leaking injector. the engine should be running rough or rich and should have turned on the engine light. there are not any other ways to get gas in the oil but these are the most common but again the engine would not run to good and the check eng light would be on. the injector depending on the injection system would flood out the cylinder and make it skip inorder to get gas in oil, the most common would have to be the regulator leaking, but that would also make it run rich, if you remove the upper intake pelinum and turn ignition on but DONT try to start engine, a matter of fact dissconnect coil wire to avoid spark or a fire. with key on watch for fuel leaking out of regulator. have someone turn key on as you look at regulator.

yes, it could be a relay... you could also have a leak. Is the pump in the tank or outside the tank? if inside,. you may want to recheck your work..

1993 chevrolet silverado 1500 will not start has new filter and pump can spray fuel in to it will start then dies when it runs out of the fuel sprayed it it


It sounds like your injectors are not firing which could be a crank signal problem or wiring,distributor pickup coil problem or a computer problem.One wire to your injector should be pink this is the power wire it should have around 11.5-12 volts with the key on. The other wire is ground that the computer uses to fire the injector which you can check with a good test light hooked to voltage. and work back from that point if you have neither at the injector.

there is 2 injectors on your truck and one is the start injector and its job is to inject a blast of fuel into the intake when the key is turned on. that injector is either faulty, clogged, or not getting any power.

I have a 1999 Chevy Suburban that is sometimes hard to start. Most of the time it starts just fine. Then sometimes it acts like it is flooded. After waiting for an hour, it starts right up. Installed new...


Hi there,
One of two things can go wrong here. The fuel pressure is supposed to stay after you shut off the eng or key. The reason for this is so the eng does not have to keep cranking while the pump builds up pressure. The fuel pump has a check valve that will hold the pressure and the injectors will hold on the other end. If the injectors are leaking fuel when you shut the key off you should be able to look down the intake after removing the air cleaner and see if fuel sprays down into it after you have someone cycle the key for you. I believe you still have the throttle body injection so i would start there to see if fuel is leaking past the injector. If it is not then the pump has a bad check vale but this is just the tip of the ice berg. Neither of these conditions will cause it not to start. It will just crank longer before it does. in other words don't concentrate on this to fix the no start condition. Be sure you have a good battery. If battery voltage drops below 10 volts when you are cranking it, it will not start because the computer will not fire the injectors. It will still crank but just not start.
