Electric fuel pumps are only engaged for a few seconds when the key is first turned on. If the engine doesn't start, the pump is turned off. If THAT's not what you're seeing, check the fuse and the relay.
your car has a starter motor that is powered by the battery when you turn the key. it is verry possable that this motor is shot. a mechanic can check very easily if it is
The remote just connects the starter selenoid with the battery, when it completes the circuit, the engine starts and will run until it runs out of gas or the engine is disabled.
If the timing is off by a few degrees the engine can start but will run rough. More than a few (depending on the engine) it will not start.
It could be as simple as a leaking fuel pressure regulator that allows fuel pressure to drop when the engine is turned off, and it's not getting up to pressure when you try to start the engine. Try this: Next time the engine sits for a while and you're ready to start it, turn the key on but don't try to start the engine. Leave the key on for about five seconds then turn it off. Repeat the process, THEN try to start the engine. It might help but then again, if it doesn't you aren't out anything.
After washing as i turn on the engine, the BAS light is turned on and the lights weakened and not started.
You have enough battery power to power the radio, but not enough to turn over your engine. CHeck battery.
It should turn on when you start the engine
It's a relay. Which one it depends... I would start from testing headlights relay.
does the sound come from the engine,or the radio???
When the engine is on, batteries are being recharged. If you use a lot of electric power when the engine is off, you can drain your battery to the point where it will no longer be able to start your engine, and you will need to jump-start it.
You likely do not have the "Constant Power" wire connected at the back of your radio deck, it is often yellow in color.
check the battery and connections/cables
I had the same thing happen to me and my 96' suburban. It turned out to be that the battery was shot and wouldn't hold enough of a charge to turn over the engine. Might be the same thing with you.
Your battery terminals are most likely corroded or loose, but if you have no trouble starting the engine your radio constant power wire may be hooked up to a circuit that only works with the key on.
Grab the key you inserted and turned to start it and rotate it back toward you, the engine will stop.
There has to be more information before the question can be answered. Does the engine crank when the ignition is turned? There are three things an engine must have to be able to start. You must have fuel, fire, and air. If one of those is missing then it will not start.
