Question Answered: 

Bolted to the intake by the throttle body (on a 4.6). Did you have someone diagnose it? They do go bad but are not very common.

Question Answered: 

If it is the pump not much you can do but replace it but there are other parts that could have went bad that may be less expensive. Have is diagnosed by someone with the knowledge and equipment first.

Question Answered: 

You have the engine strut mounts (2) on the top near the radiator, kind of looks like a tuning fork. There is a front engine mount under the right front of the engine and the automatic transmission mount under the transmission on the left front of vehicle. The front engine mount usually needs the front cradle to be lowered to gain enough room to remove. I highly recommend having someone with the proper tools and equipment to safely support the engine while the cradle is loose do the job.

It could be the belts. In the morning when it's running and making the noise spray a little water on the belts and see if the noise goes away. If it does start with belts and while they are off inspect the tensioner and idler pulleys by spinning them and listening for noise. Replace as needed. The vehicle needs to be jacked up with the front right tire removed to replace belt. If you don't have the equipment to do it safely take it to a good shop.

To many things it could be... Crank sensor, ignition module, fuel pump, PCM, wiring, and the list goes on. Take it to a good shop who will spend the time to have it stall for them. They will have the equipment already attached to the vehicle and will be able to pinpoint the problem when it is not starting. This may take awhile so plan on leaving it for a couple of days. Guessing can get expensive.

Question Answered: 

P0727 Engine Speed Signal Circuit Low Input - With Automatic Transmission Possible Causes... Engine speed signal circuit is open (PCM to the TCM) Engine speed signal circuit shorted to ground (PCM to TCM) TCM or PCM has failed Setting Conditions... Engine running; throttle angle from 5-94%, gear selector not indicating Park or Neutral position, and the TCM detected the Engine Speed signal indicated less than 96 rpm. This code sets in 2 Trip(s). This code will turn on the MIL (Malfunction Indicator Lamp) Take it to a shop with proper testing equipment and get it diagnosed. Could be a couple of different sensor giving a false signal causing this problem.

Question Answered: 

Depending on how the sensor is reading wrong I don't recommend driving it much. There is a possibility of the vehicle causing damage to the catalytic convertors due to it not having the proper fuel / air mix. To replace the convertors will be even more expense for they are not cheep.

Question Answered: 

When you pull both heads on a vehicle to replace the head gaskets the proper way, depending on the mileage of the vehicle, is to have a valve job and resurface performed. Considering the time and expense to do this and again depending on the mileage of the vehicle the shop may be recommending a whole engine due to cost effectiveness and the warranty available with a complete engine. Just doing the heads and gaskets may cause issues with the rest of the engine later. Have the shop explain to you what their advantages are of a whole engine compared to the gasket.

Question Answered: 

It is the fuel gauge or the sending unit. The fuel gauge is on the instrument panel and the sending unit is in the fuel tank. A properly equipped shop can test the gauge but it is difficult to test the sending unit in the vehicle. That being said... The sending unit is most likely the issue due to age. You will need to remove fuel tank to replace sending unit. The fuel pump is attached to the sending unit and we recommend replacing the whole assembly as a unit. This will be a difficult job to do yourself safely due to having to get the tank out from under the vehicle and fuel lines being opened. If you decide to do it yourself do not cheep out on the part. Pay more for the high quality part because you will not wish to do it again.
