Hi, I changed the fuel filter but neglected to relieve the pressure on the system beforehand (by disconnecting the fuel pump). The car now will start but only runs for a few seconds before dying. Is this due to my not relieving the pressure first? Is there another possible reason? Is there a workaround?
At my wits end...

IMPORTANT: Do not skip the fuel system pressure release step. Injury and other damage can result! Safety Step! Relieving Fuel System Pressure
· allow engine to cool · relieve fuel system pressure · put on your eye protection Before you begin the job of replacing your fuel filter, you must
relieve the pressure in your fuel system. A fuel injection system
operates under very high pressure. If you don't release this pressure
before you start unscrewing fuel lines the result can be explosive. Do
this before you attempt to change the fuel filter. To release the
pressure in your fuel lines (and fuel filter) you'll need to locate the
fuel pump fuse in the fuse box. If you don't have a fuel pump fuse,
find the relay that operates the fuel pump. Once you've found the fuel
pump fuse or relay, start the car. With the engine running, pull the
fuse or relay out. If you pulled the right one, the engine will quickly
die. Since it's using all of the pressurized fuel in the system, the
fuel lines won't be pressurized when you crack the fittings on your
fuel filter. Now that you've relieved the fuel pressure you can remove the old fuel filter. If you didn't do this yet, you must go to the previous step and do it. Very dangerous!

Yes, there is still pressure in the fuel lines even when the vehicle is not running. You can relieve the pressure by depressing the valve on the fuel line in the hood compartment. Be sure to use a rag. Also, take off your fuel cap to relieve additional pressure in the system.
