Maintenance required lights are an oil change light (as long as it's yellow). The shop may have just forgot to reset it. It happens. Take it back and have them double check it or... Reset the system by the following procedure: Turn the ignition key to the "OFF" position with the odometer reading shown. Turn the ignition key to the "ON" position while holding down the trip meter reset knob. Hold down the knob for at least 5 seconds. Dashes will bling and slowly count down off the odometer display. Wait until the odometer indicates "000000" and the light goes off. Now you can release the trip meter reset knob. If the system fails to reset, the light will continue flashing.
A couple of ideas - If the trip reset button is close the the speedometer needle sometimes you can bend a paper clip CAREFULLY slide it in the hole and flip the needle back around. Be careful not to scratch the face of the instrument panel. - Use a strong magnet and a soft cloth. Put the cloth on the magnet and hold it up to the panel by the needle and move it around trying to get it to move that way. Sometimes it works sometime it don't. - Go to a shop and have them do an gauge sweep test with there scanner. Only other thing to do is remove the cluster take the clear lens off and move the needle by hand.
Check all connections at the battery and starter. Make sure they are in good shape, clean, and tight. Remember that at the point of no crank the starter is hot so if it was tested out of the vehicle at that point it was cool and may test fine. What will really need to happen to diagnose it properly is to drive it, let it sit so it won't crank and test for battery voltage at the small wire at the starter. If you have voltage (12+) when you turn the key to the crank position then it's most likely a starter. If you don't have voltage then it could be a relay, neutral safety switch, PCM, antitheft system or other issues. At that point a good shop will be advised so you're not guessing and spending money where it's not needed.
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.
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.
Check fuel pressure... should be around 49 psi.
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.
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.
