1999 Ford Expedition - fuel pump not working after replaced alter

Is the check engine light flashing? Have you determined the cylinder is getting fuel and the injector is ok? Does the cylinder have good compression? Is there any intake vacuum leak? Are any other fault codes present when you run a fault code test?

Have the battery tested and if its good check fuses. If its not that its a wiring issue.

Check the fuel pump cut off switch, may need reseting. On the right side up in the corner of the foot well were the carpet ends.
Some are behind that kick panel, they have a button on the top that you need to press to reset.

No fuel - fuel pump failing or fuse to the pump open, fuel safety cut off / inertia switch has been operated (in a collision recently?), ignition electrics trouble (no spark at plug), computer issues..

There could be many reasons for it stalling out at lights. The first things I would check is the battery and alternator. The auto parts stores will check both for free.

The blinking engine light indicates your problems are severe and could cause more damage to the engine if not corrected. You will need to have a diagnostic scan run to retrieve the trouble codes that are causing the light to come on & flash. From those codes, repairs needed can be determined.
I hope this helps.

It's the battery. Hence why it starts when you charge or jump it. Snag a new battery and don't forget to bring your old one to avoid a core charge.

OK, there are fuses on the driver's side down below.

But, if you are having a fuel pump problem, it's likely that the fuse is alright and you need to replace the fuel pump. Same thing happened to our 1999 Ford Expedition Eddie Bauer Edition. It quit working. And the inertia fuel cutoff switch didn't help, either (flipping or pushing it).

So, if you have no fuel coming, it may very well be the fuel pump.

We changed ours around 112000mi.

I got a 1999 Ford Taurus I have a new battery and a new alternator and now I am not getting nothing from it. What can cause this?
