Water is the problem on this bike. When on the side stand water is trapped on the cam cover where the timing chain is, then water runs into 1 and 2 spark well. remove plugs and dry out, its a problem since 1986.

Your igntion coils/coil might have a crack in them ,when the engine is hot the heat will open the crack up and cause ignition problems,remove tank when engine hot and see if you can see any damage..

98eagle talon won't start,it turns over but the motor won't start.what could be the problam


Hi William:
2 ingredients:

Fuel - Has to be getting into cylinders.
Spark - Hot blue spark needed at tup of spark plugs

Either you have run out of gas, or a component has failed.
If you have spark, I would be suspicious of a fuel pump failure so would check fuel pressure. Should be about 40PSI.

How many and where are the spark plugs located on


Top of the hot bit in the engine, just follow the only 6-7mm thick cable that goes in to the yop of the engine. If it's the single cylinder model then only 1 spark plug. (2 cylinders = 2 spark pluge, 3 cylinders = 3 plugs etc.)

I have a 2006 dodge magnum it will start sometime fine but then it will start then about 3 seconds it would cut off to it to dodge twice they cant find out anything changed the battery got i new key...


can i buy a comma., says Vanna White>?
one rule of dealers, (avoid them use independent ASE shops)
or go broke. ($25 spark plugs there... i warned yah)
rule 2,
never take a car to any dealer unless you can DEMONSTRATE the failure. most shops can NOT fix cars that work,
they will try, and charge you CASH for trying, and no blush.

my impression is, the cars issues are INTERMITTENT.
if you dont know cars and electrics, then it may be impossible for you.
but some nicer independant shops might drive it for a day for you
to get it to fail. that WORKS, see WHY?

your engine stalls. that is the key word, random STALLS.
now lets work that IDEA.
there are 3 paths (one of them works out to 50 causes)
here they are..
1 bad DC power, 2 bad engine , or 3 vbad ISC controls.
all my answers ASSUME the car is 100% tunedup using the 60k miles column ! or up to 100k on some. cars. did you?
when it stalls can YOUR right foot (fast moving) save the stall.
??????????????????
does the stalled engine easily restart?????????????????????


The engine brain, PCM/ECU does all it can to stop stalls.
it does, if it stalls, its a very serious failure !
Now the full list ,( expanded)
1: lost of 12vdc electrical power to the EFI system. (voltmeter 101)
use a voltmeter to catch it. seen even at the cig lighter port.!!!!
2: lost spark? wont restart? (do the classic spark test)
3: lost fueling ? more tests (no start, try test fuel)
3A; flooding,? spark tips soaking wet. use WIDE open throttle to start engine and cut fuel , cranking, this help , try starting with 10% throttle ti see if ISC is stuck closed.
4: bad engine, the 50 ways and engine can fail. lost compression , on any or all cylinders , will do that. hot or cold or both .???????
one way to solve problems is by elimination.
say some head valves stick, only hot and only randomly. (nasty issues)

you find that (not saying it is, i never guess)
you prove that this way, examples
good 12vdc, power, checked.
good spark, checked. on all cylinders, not just 1.
injectors test pass, no leak down test failures and the injector balance test passes. (the FSM covers these 6 tests for fuel pressure)
conclusion"
so must be engine bad, it stalls, and runs bad , restarted or not at all.
so you find compression on 2 cylinders are low , 25psi, hot.
all else was tested good so i attack the engine'.
on old engines, i do that first.

so do tell what engine does and does not fully,
your post leaves out most facts.
stalls, and can you save the stall.
and does it restart.
and do you have 12VDC power at stall.

When engine cold starts ok, but once hot and you switch off and try starting it again, it will not start, runs well and ticks over well


what engine?, they have options, there. cant fix unknown engines....
G16? J20, J25 engine? all are very diffr. motors.

hot soak failure.
probably not lost engine compression, HLA lifters. no gap
so is lost spark
you check for spark at all cylinders. if all are gone we scan the ECU.
if spark is good then its flooding, spark tips on all cyl, soaking wet
or just 1.????
all the above is $2 in special tools, just a fresh new spark plug
found in tool box..

if spark is dead.
we scan it. (all comments are for USA cars, never others)
we conn. the OBD2 tool ($9) and scan it
1: key on,
2: crank for 5 seconds and see scan tool show RPM from 250 to 300rpm. good. CKP is working bit.
3: we then release key , not off yet
4: i look at live and pending DTC,s oops, P0340/355 or ?
and you look up those DTCs and it says, bad CMP /CKP?
BINGO.

IF spark is good, then its just flooding
if yes, then ask how to do fuel tests.
fueling is last. all else must be right first.
(fuel pressure, then injector balance tests)
ask

Only starts after 2 hrs of cooling down


so did it lose spark hot?
ever do a spark test. its not hard.
on all cylinders,
if spark is good try test fuel hot at failure.

1990 honda accord wont fire


Do you have spark, do you have fuel pressure? it is one of these or a camshaft timing problem. I would start with checking the spark at the plugs 1st.

Why isnt cylinder 1 and 5 firing on a 2003 ford mustang v6


First check for worn sparkplugs and if they still god then check for spark on those cylinders by pulling the sparkplug wire off and cranking the engine over.If there is no spark then replace the coil.If there is spark i would have the injectors leaned.

My 98 5.7 vortez has two dead cylinders #2 #4 i have checked spark also took off injectors cleaned and checked but still dead. I ran compression check all at 135 to 140 but #2 #4 have zero.


Ooh...not good. There's zero compression on those two cylinders? Either timing is off, head gasket failure, valve seat failure, or piston ring failure.
