Fuel contamination, what do i need to do to repair?

If you have discovered that engine coolant is contaminating the transmission fluid in your vehicle, it is important to address this issue as soon as possible, as it can cause serious damage to your transmission. Here are some steps you can take to troubleshoot and fix the issue:

1. Identify the source of the problem: The first step is to identify why the engine coolant is contaminating the transmission fluid. This could be due to a failing radiator, a damaged transmission cooler, a blown head gasket, or another issue. You may need to take your vehicle to a mechanic to diagnose the root cause of the problem.
2. Flush the transmission: If the contamination is caught early, you may be able to simply flush the transmission to remove the contaminated fluid. This involves draining the transmission fluid, replacing the filter, and filling the system with fresh fluid.
3. Replace the radiator: If the contamination is due to a failing radiator or transmission cooler, you will need to replace the affected component. This will prevent further contamination and ensure that the transmission is cooled properly.
4. Repair the head gasket: If the contamination is due to a blown head gasket, this is a more serious issue that will require significant repairs. The head gasket will need to be replaced, and the engine will need to be inspected for any further damage.
5. Test and monitor: After the repairs are complete, it's important to test and monitor the transmission to ensure that it is functioning properly and that there is no further contamination.

It's important to note that attempting to fix the issue yourself may cause further damage, so it's best to take your vehicle to a qualified mechanic for repairs.

It should go without saying that it is not possible to provide a diagnosis of your issue without knowing the YEAR, MAKE, and MODEL of your vehicle.
That being said:

1. Need for tune-up or engine repair;
2. Poor fuel quality or fuel contamination issue;
3. Improper tire inflation;
4. Brakes out of adjustment or otherwise binding;
5. Exhaust obstruction or exhaust leak;
6. Clogged air filter (most common culprit);
7. Lead foot.

It may need a major tune-up, but more likely you are experiencing a fuel delivery problem, or have water or other contaminant in your fuel. Replace the fuel filter, then check the operation of the fuel delivery system (including the fuel pressure regulator and the fuel pump itself). If all systems in the vehicle test good, suspect contaminant in the fuel (especially if your vehicle was allowed to sit unused for a period of six months or more), and replace all fuel with new.

Modern gasolines include ethanol, which can cause water vapor to accumulate in your gas tank. Use fuel system water remover twice a year to prevent fuel contamination.

Are my injectors clogged or faulty or is there a sensor issue? How do we know without testing ! and depressed shrader valve fuel dispensed,isn't the proper way to test fuel pressure . Sounds a whole lot like you need to take your vehicle to a qualified repair shop.

Sounds like a bad head gasket. You need to check cylinder compression with a compression gauge.

remove bolts/ screws to neck at fill area, lower fuel tank and remove tube

Before spending anymore money for those parts you need to remove the fuel from the tank and remove the tank and clean it. The repair facility should have done a fuel sample test. The fuel pump could be damaged.

Then put in fresh fuel, a new fuel filter and see how it runs. The injectors can be spray tested to see how they are working. You need someone familiar with diesels to work on your engine.

If the exhaust pipe was under water in the stream it could draw water into the cylinders. The injectors are at the top of the cylinders and are pressurized. Since your husband started the car again there is only a small chance of any permanent damage and its more likely a O2 sensor in the exhaust has shorted, throwing off the computer.

If there is no "check engine" light, the sensors and injectors should be good.

if you let the tank get too low then it could mess up any contaminants inside the tank or as you say poss water in fuel from supplier, no way of proving either.one question though ? what was wrong with fuel pump...should last 80k at least...if you have an inline paper fuel filter under bonnet this will show any contaminants... very rare....

How could the pump failure contaminate the injectors when the fuel filter will catch all debris. Sounds like someone is trying to take you for a ride! Shop around for a honest repair shop,there out there! Have the fuel pump and fuel filter changed and you should be fine.I hate when shops try taking advantage of customers.
Good Luck hope things work out.

what is a fule tank? if the fuel tank is contaminated either replace or removed and cleaned at a willing radiator shop, may be you should start be checking the fuel filter, check fuel pressure aswell if a car is not operated or will not be operated use STP STABIL its cheaper than fuel system repairs
