Why are 1993 ford f150 fuel injectors not working?
1993 ford fuel injector can damage for many reasons. But here I have listed a few major problems that may make the fuel injector not work.
Faulty Solenoid: Proper functioning of the solenoid is essential for pulling the fuel injector pintle. If the solenoid is open or shot, the fuel injector will fail to fulfill its responsibilities.
Bad Fuel: One of the major causes of bad fuel injectors is poor-quality fuel. If you have low-quality fuel, you will accumulate dirt and contaminations in the injector. Such impurities will decrease the fuel flow or entirely stop the fuel.
Heat Soak: Heat soak can be a cause for a bad fuel injector. When you switch off the engine, fuel residue in the injector becomes waxy and causes clogging of the injector.
Leaked/ Damaged Fuel injector: If the fuel injector leaks or damage because of the accident, you will be unable to continue smooth fuel flow.

Things you need:

I recommend the 7448A fuel injection cleaner canister by OTC Tools. It is designed for directly cleaning the fuel injectors. Dust, debris, or other residuals are loosened and combusted to remove them through the exhaust system.
You can apply up to 30,000 PSI. The canister is stainless steel made and also has a gauge for pressure. You will find this simple but very effective.
You may find hundreds of fuel injector cleaners in the market, but my recommendation is Sledgehammer.
It quickly removes the deposits from injectors, valves, and combustion chambers. You will find it awesome against excessive Soot & Carbon deposits.
Steps to follow in cleaning f150 fuel injectors:
Step 1: Fill the Canister with Cleaner.
Shake the fuel injector cleaner and make sure all cleaner mix well. Then remove the cleaner’s cap by unscrewing it and pour the cleaner into the canister.
Do not fill it too much.
Step 2: Connect the Canister to the Fuel Injector
Remove the fuel injector top cap and insert the canister tube in the fuel injector. Make sure there is no loose option or leakage.
Step 3: Start the vehicle
After that, sit on the driver’s side and switch on the car. Leave the car in the switched-on position for a few minutes.
The cleaner will start working through the fuel injector and melting all the residues. After melting all the dust or carbon deposits, it can be easily exhausted through the exhaust system.
Step 4: Remove the Canister
Once you ensure the entire fuel injector is cleaned. Detach the canister from a fuel injector. Put the fuel injector cap back on the fuel injector. You have done the cleaning.
Test it by driving your vehicle for a few kilometers and ensure the fuel injector is working fine.
