On your Ford Ranger with the 2.3 or 2.5 liter four cylinder engine , with Fords
twin plug ignition system :
The compression plugs are on the DRIVERS side of the engine
On a 1995 Ford Ranger : I'm assuming you mean the 2.3 liter four cylinder engine with Fords twin plug ignition system ( The spark plugs for the compression / power stroke are located on the drivers side of the engine , intake side )
There are three engines available. If it's a 6 cylinder engine, 6 spark plugs. If it's the 4 cylinder engine, 8 spark plugs.
All plugs are mounted in the head. If it is V6 there are 6 plugs. If it is 4 cylinder there are 4 or 8 plugs, 2 per cylinder, depending on which engine you have.
do a compression check on that cylinder. check fuel injector for pulse.
The diesel engine, which ignites the fuel vapors by compression within a preheated cylinder.
This was a design Ford tried on the 4 cylinder engine. The 2 plugs per cylinder was supposed to give you a more complete burn of fuel thus increasing power and mileage. When replacing the plugs, install 8 on this engine.
On a 2002 Ford Ranger : The 2.3 liter Dual Over Head Cam four cylinder engine has ( 4 spark plugs )
On a 2005 Ford Ranger : The 2.3 liter Dual Over Head Cam , four cylinder engine has : ( 4 spark plugs )
In a 2000 Ford Ranger : ( the 2.5 liter four cylinder engine , which was the only four cylinder engine offered from the factory for a 2000 Ford Ranger , not like the 2001 model when they started with the 2.3 liter DOHC later that model year )
a diesel engine uses compression and has no need of spark plugs
( 8 ) sparkplugs for the 2.3 liter 4 cylinder engine in a 1997 Ford Ranger with Fords twin plug ignition system
Because your 4 cylinder has ( 2 ) spark plugs per engine cylinder , a total of ( 8 spark plugs ) with Fords twin plug ignition system
