Hello,
I have a 2000 Ford Taurus 3.0L DOHC V6 Duratec with 158,000 that currently will turn over but will not start. For the past two weeks I have noticed that the car when the gas is pressed lags or lurches a slight amount before you can feel the transmission kick in. Almost as it missed a cog on a gear and then catches abruptly.
Today all of the sudden (I have not had engine starting problems since last winter) while parked in a warm underground garage the car will not start. The car has power and the headlights flicker when the starter is trying to start the car. I cannot hear the fuel pump running when listening at the gas cap (dont know if that even works on a Taurus I saw a video for a Ford pickup diagnoising this issue). I have checked the fuse box, no burned out fuses.
That is the extent of which I have troubleshot the issue. Anything else you can recommend? I am not a gear head by any means but I am willing to do what I can to get this pile of junk running without running me up a huge bill.

All "crank, no start" conditions are approached in the same way. Every engine requires certain functions to be able to run. Some of these functions rely on specific components to work and some components are part of more than one function so it is important to see the whole picture to be able to conclude anything about what may have failed. Also, these functions can ONLY be tested during the failure. Any other time and they will simply test good because the problem isn't present at the moment.
If you approach this in any other way, you are merely guessing and that only serves to replace unnecessary parts and wastes money.
Every engine requires spark, fuel and compression to run. That's what we have to look for.
These are the basics that need to be tested and will give us the info required to isolate a cause.
1) Test for spark at the plug end of the wire using a spark tester. If none found, check for power supply on the + terminal of the coil with the key on.
2) Test for injector pulse using a small bulb called a noid light. If none found, check for power supply at one side of the injector with the key on.
3) Use a fuel pressure gauge to test for correct fuel pressure, also noticing if the pressure holds when key is shut off.
4) If all of these things check good, then you would need to do a complete compression test.
Once you have determined which of these functions has dropped out,
you will know which system is having the problem.

The one thing I would check 1st on this is the fuel pump inertia switch in the truck. If someone bump the car in the garage it may have tripped the switch......There is a reset button on the top, if tripped just push it back down (you'll feel it click).
If the switch is good, then start on the flowchart HT posted and that will let you know what you are missing....
