Question Ford Explorer 1991 V6 4.0L injector replacement ???

Hello:

Well my Explorer have 2 pistons without combustion ..

The spark plug are clean on those pistons ..

It have spark on those cylinders ..

I check the piston compression and the compression is more than 150 Lbs.., sometimes 165 lbs .

The Explorer is old and I assume that is ok for old 1991 motor,,

No big difference between cylinders compression ..

I think ok ???

Suggestions welcome ..

I think I have a some fuel injector problem ..

I want to check the injectors ..

What Can I do ???

Please somebody give me the instructions to check and replace the injectors .

If have photos .. better ..

Thanks in advance

the reads out are between 155-165 lbs .. some times more ..

Too get a accurate compression reading, all 6 cylinders need to be tested, but the ones you did seem fine.

Have you checked the ignition coils?

If the spark plugs are really clean, then that could be a sign of a leaking headgasket. The antifreeze will steam and basically clean the plugs.

Ford Explorer 1991 6V 4.0L

I check the spark in the spark plugs and seem to be ok in all spark plugs..

With the motor running , I remove the cable from electronic ignition of each piston , the spark jump over a inch of separation between cable and electronic ignition in all cables ..

The involved spark plugs are clean because are completely new spark plugs.

There is no steam or water in the exhaust system.

There is no oil in the radiator .

There is no water in the oil .

Why should not be the injector ??

You can rent a fuel rail pressure set gage from most auto stores. This will be probably be cheaper then replacing the injectors if they are not the problem.

I deleted your other thread. Please post all questions regarding one vehicle in one thread. Creating multiple threads for the same car is confusing.
