The fuel pump relay can stick or be bad. To check this, park the truck in a quiet place and get out and listen for the fuel pump, ( you mitght have to put your ear right against the tank to hear it) If you do got ot he underhood relay fuse panel and feel the relays if it's hot it's on. If you do this next step you might want to be home or where you can get a ride to the parts store ( don't doit when the store is closed ) If you hear the pump with the key off pull the relay and then listen to see if the pumpis off. Ford does'nt mark thew relays so you can refer to the owners manual ( if you have one ) or you can find it by pulling till the pump quits. this relay that you pulled you might be able to shake it or smack it and plug it back in and the pump be off. Noew the good part turn the truck on and see if it starts if it does the relay come back on. now turn it off and listen to see if the pump is off if it is you can try to trust it or go to the parts store and get a new one.

Where is the inertia switch located on a 2007 suzuki forenza?

the Daewoo wonder wagon, in snake clothing.
and 6 engines, ill guess at gasoline engine.
so what makes you think there is one, (hope:? dreams, rumors?)
you have zero fuel pressure, is that it? did you check that first?
got spark?
run on test fuel?
yes then
do you have 12vdc top the pump cranking> yes/no,

there is no electric fuel switch, period, only the Std, fuel pump relay
that PCM operates only.

that leaves fuel line switches (inertial fuel valves, real name)
and the fuel diagram, shows, no such part.! it's not there, in USA car
is it a USA car?
so you are guessing.?
thanks for the goose chase. what a waste.
why not , post the symptoms and get real DIAGNOSTIC help
and avoid this goose chase.

2003 chevy cavalier will not start after sitting overnight

Usually the sign of a bad fuel pump check valve that allows fuel pressure to bleed off over night. Try this in the morning. Turn the key to ON for 2-secs, then OFF. Repeat 3 times. Then try to start. If it starts right up, you need a new fuel pump. By turning the key on and off you're filling the fuel lines and building pressure that you lost overnight.

Hello, I have a 99 silverado z71, I was driving along and all of the sudden it lost power and started to spit and sputter and ended up on the side of the road,sitting there it continued to idle roughly,...

Have the shop check fuel pressure at the fuel rail. Maybe the pump impeller has failed. If fuel pressure is good, your timing chain/belt may have slipped.

99 chevy express van 5.7 wont start after sitting for a day. fuel pump is new,it has spark,and no codes.

A new fuel pump can go bad but you need to know if the fuel rail has pressure or fuel in it the next day. Take something and press on the shradder valve on th fuel rail and see if you have any fuel. If not the fuel pump may be installed wrong.The fuel rail should have some pressure all the time for quick start up. I do not know if this helps but it is a start.

I've had similar problems on Fords whit batteries going dead very quickly the fastest one was a relay stuck on specifically the fuel pump relay(1986 tbird) and once it was the EEC power relay (1991 F150) both caused the fuel pump to stay running and in less than an hour my battery was dead. I also had an f150 (92) that had a bad glove box light switch) but it would take a day or so. I'd check to see if you have a bad relay that is causing a motor to run, fuel pump, or electric cooling fan(if equipped) otherwise you have some sort of short in the system draining your battery they are usually not so quick.
