it would be easier to answer if one knew what was meant
Replace the fuel filter, that is a good place to start.
why does it matter if you're driving down a hill? At least it didn't cut off when you were driving up a hill? And I don't know why it would cut off I'm 13.
If the engine won't turn over, clean the battery cables. If it will turnover but not start, findout if it needs fire or fuel to run then go from there.
What would cause my VW golf to cut out whist driving
The cause for a 1991 Ford Taurus to just cut off while driving is probably a problem with the computer. If the car will start again after about 90 minutes, then check the computer module for code errors.
timing is off check it
If you mean 'cut off' as in the car dies while driving its probably your alternator.
A faulty engine coolant temp sensor can cause that.
Change air filter and clean or replace spark plugs
Cut them off- after 10 years it's time to replace
It may be fuel pump,but likely not.Try finding out if it has a fuel pump resister in the wiring harness. If so you can bypass it to make it run. Hope this works.
My 1995 would cut off while driving ,i'd turn ignition off and start right back up found that the fuel pump was going bad replaced and works great. You have to pull the tank it's inside , be careful when working around fuel if your'e not mechanically inclined hope that helps
