Look in the trunk and you will see the air ride switch. Look on further back behind it and you will find the fuel cut off switch. Just check it to see if it needs to be pressed back in or not. I'm not sure if the fuel pump would burn up with the switch being left on all night or not. I don't think anyone here has ever tried that before.

thanks,i did that,and nothing....do you know if there is only one relay?

Really not sure but I don't think so. You could always try to disconnect the battery for about 10 min or so and then reconnect and see what you have from there. Maybe the PCM needs to be reset and then again, setting like that could have burned the pump up. When you turn the key on, do you hear the pump humming? I know you hear a clicking noise but that's just your shock solenoids in the rear doing that, if you still have them connected. Listen for the pump to turn on.

You left the key on all night, and the battery isn't dead?

 

[soulcanvis]

it was near dead,i hooked a charger up to it.

Sounds totalled...sell it cheap

Try leaving the charger on a low setting overnight with the battery disconnected.

Reconnect the battery in the morning and cross your fingers.

it has a good charge to it,i herd there is a relay by the trunk hinge same side as the rest,not around the car to look. and i know the car has atleast 4 gallons of gas in it,that should be enough to reach the pump

no i dont hear the pump,how do i reset the pcm?

By disconnecting the battery for a few minutes.

 

[soulcanvis]

weird,did that (reset pcm) and now i have nothing,no power at all,lol car is the devil

Keep it disconnected for a while and make sure the battery is taking a charge. You might have a dead cell but if not, it needs to charge up completely because if not, you will likely burn up your alternator when you do get it running. Marks love eating up an alternator with a half dead battery. If you got nothing at all, you either had very little connection from possible corrosion or just didn't have the terminals on good and tight but the battery needs to be fully charged and don't rush it.

I bet the battery won't pass a load test. You can charge it overnight and then take it to have it tested. If it is bad, the alternator will be next to go as others have said.
