Where do you put starting fluid in 1989 ford f150


You would spray it into the throttle body by removing the rubber hose between the body and the air cleaner box.
Open the throttle plate before you spray.

I have a 1990 Ford F-150 5.0 with a no start issue. I have spark, fuel,and air. fuel pressue 40 psi, good compression. I had to replace the tps.


Check that the TPS was installed correctly. If not, she won't start. You have to align it with the slot in the throttle-body housing and turn it slightly to seat it onto the hole correctly.

starting fluid is a thing of the past. dont use it. this car doesnt have a carb, its a throttle body/ electronic fuel injection system. you most likely have a fuel pump or fuel pressure regulator issue. test the fuel pressure, should be anywheres from 35-50 psi

Did you also change the Coolant Temperature Sensor? If it is reading wrong, the computer may not realize the engine is cold, and won't increase the gas for that.
Spray some carb cleaner around the outside of the throttle shaft, if engine speed increases, that could be a vacuum leak. I've never heard of that, but anything is possible. It sounds like it would have to be a serious air or vacuum leak to cause your problem. Have you blocked off the power brake booster to check if that is leaking?

You might want to do a compression test to see if there is any internal mechanical damage.

We have a 1990 f-150 it wont start but will crank


Take some throttle body cleaner and spray it into the throttle body then try to start it. If it fires up for a second then shuts off you need to change fuel pump or fuel filter. If that dont work check for spark. check the distributers cap and rotor. Also check the coil to see if your getting any spark from there

I have a 2001 Mazda tribute it cranks but won't start.


You need 3 things for a car to start. Air, Fuel, Spark. Take some throttle body cleaner and spray it in the throttle body, If it starts you are not getting fuel. Use a spark tester and check if you have spark if not check crank position sensor, and coils. And obviously check your air filter box for anything keeping air from coming in.

1997 ford truck will start wont hold idle


I would start with checking the IAC ( Idle Air Control ) on the back of the throttle body. This provides air to the throttle body when the butterfly is closed ( idle ). Some times they build up gunk in there, and the valve cannot work correctly.

The IAC is on the back of the throttle body, you will need to remove the plastic throttle body cover to get to it.

There are 2; 8 mm ( 9 ? ) bolts holding this on to the throttel body, remove the bolts, and unplug the connector and the tube. Spray the IAC with throttle body cleaner that is MAFS ( Mass AirFlow Sensor ) safe a few times until the clear runs clean. Let dry and reinstall. Might need to be repalced, but worth checking on cleaning 1st.

2002 ford taurus won't start at first crank in the morning


remove the air filter housing from the throttle body, or if its mult-ported injection, remove the large air duct. Do this the night before. The next day, before cranking and having a spray can of carb. cleaner, spray a couple of shots of carb cleaner either into the large air duct, spray towards the engine, or if its single body injection, spray directly on to the throttle body.

Crank engine immediately, preferrably have some one else sitting in the car to start it after you spray.

If the car even tries to start, replace cold start relay.
