Question about 1984 Ford LTD

Open Question

My 84 ltd 5.0 wont start after you first start it unless you shoot starter fluid in the intake of the injecters

It usually starta right up the first time, but if you turn it off you have to shoot starter fluid in it to get it to start again. it is fuel injected

check to see that you have fuel all the way to the engine.to do this: pull the fuel pump fuse and, crank the engine a few times to releive pressure then open the fuel line, cover it with a rag for safety then: replace the fuse and, crank the engine just for a second or, two if no fuel comes out it's another fuel filter probably on the truck frame rail that is the problem or, low pressure from the fuel pump

SOURCE: i have fuel pressure but the engine wont start

Not likely. I believe the injectors have 12 volts going to them all the time. The PCM then grounds them so they operate when the crankshaft or camshaft sensor tell the PCM when the cylinder is on compression stroke.

I would check for an injector fuse first (see owner manual), and then check to see if you have a bad crank or camshaft sensor.

The PCM very rarely fails.

Section 03-14: Engine Controls, Electronic 1994 All Aerostar, Ranger, and Explorer Vehicles Workshop Manual
DESCRIPTION AND OPERATION Powertrain Control Module (PCM) The center of the EEC-IV system is a microprocessor called the powertrain control module . It receives data from various sensors:

  • Throttle position sensor (TP sensor) (9B989)
  • Mass airflow sensor (MAF sensor) (12B579)
  • Intake air temperature sensor (IAT sensor) (12A697)
  • Engine coolant temperature sensor (ECT sensor) (12A648)
  • Heated oxygen sensor (HO2S) (9F472)
  • Camshaft Position (CMP) Sensor
  • Crankshaft position sensor (CKP sensor) (6C351)
  • Power Steering Pressure (PSP) Switch
The powertrain control module contains specific calibrations for optimizing emissions controls, fuel economy, and driveability. Based on information received and programmed into its memory, the processor sends signals to control various actuators:
  • Fuel injector nozzle tip (9E527)
  • Ignition coil (12029)(s)
  • Idle air control valve (IAC valve) (9F715)
  • Ignition control module (ICM) (12A297)
  • EGR vacuum regulator control (9J459)
  • EGR external pressure valve (9F483)

Hello! The Throttle Positioning Sensor (TPS) is defective...It is bolted to the throttle body...It is a round black device about the size of a 1/2 dollar, with a mounting hole on each side...It has a 3 wire connector...Wire colors are...Gray/White...Gray/Red...And Brown/White...Cost $55...Use 2 safety pins...Push the pointed end into the rear of the connector on the Gray/White wire and the other on the Gray/Red wire...Do not disconnect the connector...Set a volt meter to read a maximum of 5 volts...Place the + probe on the Gray/White wire...The - probe on the Gray/Red...Turn the key to on...Voltage must be less then 1 volt (.85)...If not TPS is defective...

Do not move probes...Start the engine (if you can)...Watch the meter...Slowly increase the throttle...Voltage must rise to 4 volts (wide open throttle)...As voltage rises...If the voltage skips, jumps, or acts erratic the TPS is defective...

My mule will not keep running. Stopped suddenly after good start. Replaced the fuel pump. Still will not keep running. Fires. Then stops. Fires on starting fluid. What could it be?


When you say it fires with starting fluid can you keep it running with the starting fluid or does it just fire while cranking the starter then stop when the key is turned to run if it keeps running with the starting fluid then you still have a pump problem or the filter could be plugged or the carb could be bad but if it'd fuel injection then it might just not getting enough pressure fuel injection takes high pressure

Timing is right on, good compression, got spark, good fuel pressure, wont start or even try


Try some engine starter fluid. Spray in the intake and see if the engine will at least try to start. If so, you have a fuel problem. If its fuel injected, something could be keeping the injectors from opening.

What would make a 1988 2.5L celebrity crank an run some time but other times have to spray starter fluid in injection to start


Having to spray starter fluid is an indication of lack of fuel. Possible restricted fuel filter or fuel pump getting bad. If the problem occurs in the AM when vehicle is cold and is started for the first time, there may be an issue with the coolant temp sensor providing inaccurate information to the computer. Have the computer scanned and monitor operating parameters of the sensors to help isolate the cause of the problem

Where is the fuel pump relay switch on a 1988 Ford Crown Victoria 5.0


The computer controls the injection of the fuel. If you look at the wiring diagram you will note the bottom 4 pins that are the negative and positive to the left and right injection. Atleast on my 1991 it is .Could be the ecm or computer is sending a false signal or not sending one at all. A sign of this is the fuel pump in the gas tank can be heard and will continue to run as if pressure in the fuel system is not building. Tthe truck want crank as if no fuel. When starter fluid is injected into the Throttle body the egine will start and run untill fluid is used up. It will keep running as long as fluid is added.

I have good spark on all 4 cylinders but it won't start up, i already replace the fuel filter.


Get some starting fluid and shoot it in the throttle bore while someone turns the starter ,if this starts the car this confirms it is a fuel problem if it starts. second check fuel pressure with fuel pressure gauge depending if it is carburetor or fuel injected (fuel injected is anywhere from 35 to 55 p.s.i) (carburetor type 8 to 12 p.s.i.) t.this is the starting point.check fuses to relays and if ok the fuel pump is at fault and needs to be replaced.
Thank you for your questions

87FordRanger 5spd 2.9l. Bad starter. Truck sat for month and a half with very little gas. Changed starter for rebuilt. Put in gas. Motor turned over, but no start. Tried a few more times. No start. Last...


Your starter solenoid stuck on. (This may be internal to the starter). You need to replace the solenoid (or starter), then get the battery charged, and try again. If this has a carburetor (rather than fuel injection), you may need to prime it with starter fluid or a little gas in the throat of the carb (put the air filter assembly back on before you try to start it, you don't want to start a fire).
