What do you do if the 1 and 4 piston is not firing Replaced the coil pack Compression is 190 on each Dont know what else to do 2001 ford Focus Please help again?
Well, if disconnecting the battery for about an hour so the brain (computer)could reset itself didn't work, looks like you need to go to a used parts place (junkyard) and get a brain and try it. If that's not what it is they will probably refund you if it's a reputable place. But, more than likely that's the problem. If the coil is firing 2 cylinders it would fire all 4 unless it's not getting a signal from the brain. Check the distributor for a crack??
What else can I help you with?
What piston must be at the top when firing order is 1-3-4-2?
#1 piston must be at TDC / Top Dead Center on the compression stroke.
Piston firing order?
Depends on engine and manufacturer - please be more specific.
Why is an engine times?
Engine timing is the way that the spark is synchronized to the end of the compression stroke of the piston. Firing early will fight against the engine's normal movement and firing late will reduce power to the wheels.
What causes no compression in a 2 stroke dirt bike?
No compression could be various things from your piston to your crank start with your piston by doing a compression test
Why wont motor start with wrong firing order?
Because the spark plug must fire when the piston is at top dead centre of a compression stroke. If the plug fires when the piston is at any other position then you get backfiring etc and no start. The correct firing order ensures the plugs fire at the right time.
What the internal combustion engine made?
pre ignition , example : carboned up piston crown retains heat from previous burn and combined with compression , self ignites before firing point tending to stall rising piston
What made the internal combustion engine knock?
pre ignition , example : carboned up piston crown retains heat from previous burn and combined with compression , self ignites before firing point tending to stall rising piston
What is the work of a piston?
piston work of the compress air and fuel compression
Does the first piston return to the top position once for firing and once for discharge and can you get the firing order off 360 degrees?
Yes - at the compression stroke both valves are closed (ready to fire) at the exhaust stroke the exhaust valve is open
Why would a motor loose compression in a 5th cylinder when it is a 6 cylinder?
from what i know there is no difference in what piston loses compression based on the layout. a piston loses compression due to faulty valves/seats/stems or damaged piston rings. if you have low compression problems, check the above, in that order
Why is your Honda Civic DX blowing oil into the air filter and carburetor even after you replaced the PCV valve?
it either needs new rings on pistios or one piston is cracked causing blow by or ... blow by is when compression escapes your piston..
What is the reason of miss firing in a gasoline engine?
Bad spark plug Bad plug wire Bad valve Bad piston Do a compression test to see if problem is engine internal
