The fb 25 weedeater has fired off a time or 2 one time it started but died like 2 seconds and only fired one more time with25 pulles

Put a little in the cylinder via the spark plug hole and see it will run a second or two. If it does then your carburetor needs repairs or replacing.

Most shops will not even accept these cheap unit in for repairs.

Why won't my jeep start after replacing the battery & the spark plugs?

Need four basics to start the engine; timing, spark, fuel and air.

Is the engine cranking? If so, have someone to spray 'starter fluid' into the immediate air induction port. If it doesn't fire and run for a few seconds, check the distributor source. If it does fire and run for a second or two, you may have a fuel pump down.

1993 Grand Cherokee Lardo runs great then it decides it does not want to start

THE JEEP ZJ ! NO ENGINE STATED, so real hard to help !!!!
cranks robustly (crank shaft actually turns, look)
and will not start.?
no engine stated, there are many , must know engine to fix them.
so did you check spark at all cylinders. ?
and timing of them.
and spark wire firing order, one guy had a friend swap them for fun.
(he had a accident later.. LOL)
if spark is hot on all 4 or 6 cylinders.
and #1 fires near zero on the pulley, then
try test fuel, spray it. runs for 3 seconds and sounds good.
that mean engine and spark are good and you lost fueling
the steps are same 1920 to now, on mr. otto cycle engines.

a 60k tune up is more.
1: spark plugs , J plugs, stock & gap'ed right.
2: spark wire. new.
3: cap and rotor.
4: air filter, and fuel filter.

when you replaced the dizzy(why?) did you read the FSM
to retime it, it times injection too.
be sad to make it worse throwing parts on top of a good dizzy

there is no reason to replace the DIZZY unless
one of these fails #42 or 54. 54 is dead dizzy Cmp sensor.
ever see this? DIAGNOSICS.

got a ignition spark strobe light?, this is childs play.
check spark x6
check firing near TDC #1 , near 0 degrees. see hood spec for exact spec. (open hood ,USA, look up, see EPA, timing spec, BINGO.)
and firing order, do not cross wire to wrong plugs
do not guess at firing order or rotor direction or all this fails.
true for all cars with dizzy,
the fsm is there. no need to guess. ever


  1. if engine is good (compresson)
  2. and spark is good
  3. and not flooded, (look)
if not flooded it will run for 3 seconds, at least.
if flooded
use super secret , unflood mode, crank WOT
wide open throttle, its in the oper , guide this for all cars made, 1988 to now.

91 toyota v6 is not firing

ok , (killed?)
there are 6 spark plugs, it will take all 6 firing to run
are all 6 sparking, called a spark test.
BTW1, the ECU will not inject fuel if it even suspects spark is bad.
it has 3 monitors for spark, if one dies, fuel is cut and in many case
the fuel pump too, all cars. (fire safety)
so SPARK is first.
  1. check spark? if spark is dead.
  2. then Insert the diagnostic jumper clip (paper clip )
  3. in to the check terminal.
  4. and then crank for 5 seconds.
  5. Got DTC errors (flash codes) for CMP, or CKP dead? or spark dread codes. ? BINGO?
  6. The ECU will tell you most times if spark is bad. and why.
ever do a 60,000 mile tune up in the last decade?
if not , maybe now is that magic moment?
fuel can burn weak or no spark.
the 60k also nets you a new fuel filter .
check spark directly at the the coil too....not just the 6 spark wires.
if the coil sparks and not the 6 that means the cam belt slipped.
(hard to believe a chain can but see 2 like that, owner was deaf)

if you have spark, then test fuel works
spary it in now.
verrrommmmmmmm stall.
that means the fuel pressure is low.
if you get this far,the rest is easy, ask.

Spec vin ecu specs

If it turns, then the battery is OK. Either spark plugs are not firing in proper order (wrong firing order), no power to spark plugs, or no fuel because of fuel restrictions (dirty fuel filter). Inspect the air filter to ascertain its not clogged air. If you smell gas, then you saturated the spark plugs, which is why it refuses to run.
Let it sit for half hour to let spark plugs dry. Inspect to ascertain its not dirty spark plugs, which will also prevent engine from running. After ascertaining its proper firing order, spark plugs are clean, and there's power to distributor cap, ascertain there's fuel in fuel lines by squirting half second (short squirt) of starting fluid into air filter. Close the air filter housing to trap flammable starting fluid gas. Turn engine without giving throttle. Let starting fluid be ignited by spark plugs. If it won't start, then spark plugs are not firing to ignite starting fluid gas. If it starts briefly, but won't run when you give throttle, but catches when a 2nd person squirts more starting fluid into air filter just before engine stalls, then its a fuel restriction issue or no fuel in fuel lines.

Which fires first front or rear cylender on a 1982 FXR 1340

Neither. The front cylinder fires on one rotation of the crank and the rear cylinder fires on the second rotation or vice versa. Since both cylinders fire on different revolutions instead of the same rotation, neither fires first. But, the ignition system, provided it's stock, fires both spark plugs at the same time. It's called a dual spark system because it fires both plugs at the same time. Since one cylinder is on the exhaust stroke and is of no concequence, it's called a 'wasted spark". You can switch the spark plug wires on a stock Harley Big Twin, not the V-Rod, and it will run.

Good luck

Replaced cyl head assy, now engine won't start

Fuel pump won't run unless it starts, it is designed to run for two seconds then shut off, if it were to run and you had a damaged line you would cause a fire. The cam shaft sensor gives you spark and injector firing but the crank sensor has to work two, check to see if you pinched off the wires on the crank sensor, also does it have a coil pack? If it does leave me a post.
