Go to website lincolnvscadilac.com and try a search there. Do the lights dim when you attempt to start? Does it crank over with no start? Fuel pumps are a problem and check the fuse (40) amp for fuel pump in the trunk. Can you hear the fuel pump run when you turn key to on (not start)? I switched 7 fuses for the fuel pump before finally changing the thing.
Did you change the primary fuel filter on the frame rail? It's under the truck and looks like a tin can. Most people don't even know about it. Be sure and remove the gas cap to relieve the pressure before you change it. They cost under ten bucks at most auto stores. Good luck!
Check for fuel pressure at the valve on the fuel rail (looks like an over sized tire valve). Push the center of the valve. If you have good pressure, you will get about a 3 foot spray. If not the fuel pump or relay is bad.
From your saying looks like you have a feeding problem. Do you hear the fuel pump working? if it is working check by using the fuel pressure tester how much is the flowing pressure and if it is in the recommended pressure flow. Also check even after the fuel filter if the fuel is flowing into the rail and the pressure regulator is working. Last check if your injection system is working ,if the ecu sends a message to the injectors to work.
is fuel pump working, turn key to on listen for buzzing noise in gas tank, no noise means need pump, or check fuel pressure with fuel gauge , fuel check outlet looks like a valve stem on a bike located on fuel line near top of engine.
You might not have to change the pump at all. Get the fuel filter cleaned thoroughly, change it if required(its quite reasonably priced) and since this has MPFI (multi-point fuel injection) engine, either clean it by adding some nozzle clearing fluid or get the nozzles properly cleaned at a authorized service station, where they can connect it to a PC to check the status of the tiny holes of the injector nozzle.............................sodeep
What you just did is most of the test. Just check that there is power at the pump. If so, change it (don't forget the filter) Problem is common to most if not all electric pumps.
Pretty sure you need a new fuel pump, it may be shorting out inside or seizing up drawing too much current blowing your fuse. There easy to change, if you need info on R & R a fuel pump get back to me.
