Throttle body relay locatoin - 1995 Ford Contour

Question edited for clarity and spelling of 'throttle' / 'trotle'.

All involves the Electronic Throttle Actuation System. See the link

You didn't say what engine ect. but I would look at the stepper motor mounted on the throttle body or the Idle Air Control in the throttle body. Use throttle body/intake cleaner not brakekleen or carb cleaner.

Its rare that you have to replace the whole throttle body. The code given indicates its the throttle position sensor on the side of the throttle body. Its parallel from the actual throttle and fyi to you it only that's 10 mons to replace so don't get ripped off

Is it carved or efi??If efi do this::locate your throttle body,pull the air intake hose loose from the throttle body,spray starting fluid or carb cleaner into the throttle body opening, push the hose back onto the throttle body then try to start the car.If it starts & runs for a few seconds then dies,you've got a No Fuel problem.If it doesn't start at all,you've got a No Spark problem.If its a no fuel issue,turn the key on & listen for the fuel pump priming sound.If you don't hear it,check for a blown fuel pump fuse,defective fuel pump relay,a defective computer power relay or a tripped inertia switch.If they're OK,disconnect the harness at the fuel pump,turn the key on and use a voltmeter to test for battery voltage.If voltage is present,the pump is bad.If voltage isn't present,but its present at the fuel pump relay harness, there's most likely a short/open in the wiring harness between the FP relay & pump.You didn't list your vehicle info,so I'm unsure of which type ignition you've got.
Most no starts on a new engine are caused by a ground wire you forgot to connect,wiring harness not plugged in or a timing issue.

replace the injector and throttle body motor and relay

low voltage to the Throttle Body unit causes this problem along with a dirty buttery fly . Have the throttle body cleaned asper Jaguar cars service spec and replace the throttle body motor relay located in the engine compartment center row 2nd back . Then dissconnect the battery for 30 minutes and reconnect .

when you first turn the key on you should hear the fuel pump run for about 10 seconds . this primes the fuel system .If you do not hear the pump run then you need to check the circuits for the pump
the fuel pump has a fuse and a relay that is use to power up the pump . you should check the fuse and if they are ok then switch the fuel pump relay with a like one in the fuse box (horn relay is the same as the fuel pump relay ) I think the fuse and the relay are both in the under hood fuse box on your truck . If these all check out ok then you need to check for power and ground at the fuel pump connector . if this checks out all good then replace the fuel pump . some times if you think the pump is not working you can bang on the gas tank with a rubber mallet this may move the pump winding off of the dead spot and the truck will start ... but this is not a fix .. just a way to get it started to move it or take it to a shop

Might want to check the IAC ( Idle Ait Controller ), which is mounted to the back of the throttle body with 2 8 mm ( 7? ) head screws.

You will need to remove the plastic throttle body cover to see it.



It could be it is gummed up too bad to open for starting, and no air is making it into the throttle body.

The other reason could be the fuel pump relay is bad ( swap with one of the trailer tow adapter relays ) or the fuel inertia switch is triggered.

Hey Jruthesq

The 850 is equipped with an Idle Air Control Valve (IACV) which supplies the engine with air when idleing (a necessity since the main throttle body valve is completely closed when no throttle is applied, thus the engine would lack air without the IACV when idleing). The IACV is suspended in a rubber mount on the front of the throttle body itself, and is easily removed and inspected/cleaned. If it's dead a good cleaning usually gets it going again. Also make sure that the air from the IACV is unhindered on its way from the IACV to the throttle body (it's actually common for the holes in the throttle body to be gunked up so bad by hardened carbon deposits that one sometimes needs a nail or even a drill to open it up again).

Just thought I'd mention this since you said that the gas needs to be feathered for the engine to start. When you press down on the gas the main valve in the throttle body opens up, closing the IACV and supplying the engine with enough air.

Oh and if your fuel pump relay is a green one marked 103 you should replace it with the new and improved red one. The relay is located under the fuse box cover under the hood. Remove the 4 torx srews holding the cover in place and you'll see the relays under there.

Good luck mate!

you maybe dealing with a bad fuel pump check to see if your getting power to it if so the pump is bad bad fuel pump relays are not very commonly bad.hope this helps you !!
