SOURCE: firing orde ford 6 cyl f-150 truck distributer to spark plugs

you didn't say if you have the straight 6 or v 6.But i'll give the order for both.
The 4.9L straight 6 is 1-5-3-6-2-4----------- distributor rotor turning clockwise, and #1 plug is the first plug.
On the 3.0 and 4.2 V6 engines is 1-4-2-5-3-6-------#1 plug is the first plug on driver side---- facing engine.

SOURCE: I have a 1.8 n13 sohc pulsar that will not start.

It might have a damaged valves caused by slipped timing belt making the piston and valves banged each other. That is why the compressions are low. Big job.

SOURCE: Mazda Eunos 500 - Engine lacks power -

when you change the wires did it bring back the dead cylinder? If not check the resistance on that injector it should read 11 to 15 ohms, check another injector to see specific ohms they should be close if not exact.

SOURCE: if a cylinder shows low

1)You injectors could be clogged, and needs cleaning. Buy some fuel injector cleaner and see if you get compression back. 2) If not, have your car recently done any timming work to it?, if so, timing wasn't correctly set and top dead center isn't being fully achieved and needs to be set agian. 3) You car isn't getting the correct fuel to air ratio mixture and this is causing lost of compression, and needs to check your throttle intake or sensor. 4) Your piston cylinder suffer mechanical damage.

Does low compression on a 3.1 litre 1999 cause a p0303 code?


Could be a fuel injector, as long as you are getting around 150PSI in that hole I wouldn't think it would register a miss fire.

Why my 2006 ford f150 titan 4.6 cyl keeps coding cylinder 3 i all ready fix the threads and again now what ???


Did you re tap it or use a helicoil kit? Re tapping won't work. You need to use the kit. This is due to a poor head design only allowing about 4 threads of the plug to grab the heads threads.

1998 Acura 3.5rl My engine light came on got the codes P1206 P1399 its a misfire in cylinder6 and to start with spark plugs what should I do if it stays on And how bad this could be, please help(:


Plugs rarely cause a misfire. Bad gas mileage yes. Try swapping plug wires first and see if the misfire follows the swap. If it does, you still need a tune up, plugs wires, cap, and rotor. If it doesn't, pull the plugs and do a compression test on it. If it is within specs(sorry, I don't know the numbers). Then do a tune up. Look at number six plug. Causes for the plug to misfire would be, Cracked ceramic, fouled out from oil, and in some cases the electrode is completely burnt away.

I have a 1988 Yamaha Phazer 500 and it is not running on one cyl. Checked spark and good on both cyl and it has 130# of compression on both cyl


If spark and compression seemed good you may need to check the fuel. I would assume that cylinder has its own carburetor. Make sure it is working by spraying some starting fluid through the intake while the engine is running. If the cylinder starts firing you have a carb issue. The often gum up from storage or poor fuel.

No power one cylinder


old post, but.... others will like it in same jam....
you didnt try a new spark plug? after all spark plugs LOVE TO SHORT under pressure, !!!!!! has spark means ZERO to me.
only TECHNIQUE has meaning, HOW? Done? (3 ways )?

does your engine (displacement not stated) have a timing belt.
did you replace it on time, if not FAIL! ( off topic, but very real)

yes, YOU DO that, but , fate does rule the universe. (no guessing)
the tests are easy, why fret? gee the compression test is 5min work. ?
spark good,
injector balance test shows, injector injects same as other 3 (long tests times say 1hr done right) can advice every step. on all.

i POINT my IR gun to cyl. X, (dead) and see pyro reading of cold
oops CYL X is in fact near cold. or fully. cold.

i remove all spark plugs (read the paper in the box , with compression gauge $20) WOT testing only.
i insert the fitting in to cylinder X
i crank until the the needle goes steady.
150psi, 90 is bad timing belt , near zero is bad compression
150 or more is normal, all modern cars.
why wait?
then if it is a flat cylinder, we don't ask why, we find out why.

but in fact you can hear, what is leaking,
valves or whatever. in fact I DO ! (junk car, or fix it logic)
I have a $40 leak down tester, tool
with side tool i can hear the leak path (shop air, got shop air?)
i can hear the leak in 3 places,
head gaskets blow in up to 4 directions, far be it for me to guess.
L/Right/F/Rear
or the block or head is cracked, running pure water in the coolant
is guaranteed, are you?
water in the oil? green death to engine oil looks like chocolate milk shake.
oil in the water (signs)
see hissss tests here.

see"You find gross leakage? discovered in test 13"

http://www.fixkick.com/compressiontest.html


do the compression test WOT, or all data is useless.
WIDe OPEN THROTTLE WITH SPARK DEFEATED .

im sure you have a new head now, right?

1988 302 f-150 #5 cyl. not registering on compression test


Could be a broken rod that has left the piston up in the cylinder somewhere and not moving or there is a very large hole in it. With a spark plug out can you get a long screwdriver in there and push on it so see of the piston moves. Either way it sounds like a rebuild is in your near future.
