Starter is bad but can get engine to turn over but will not start, belt to the front of engine is good, is this the cam belt or timing belt? is there two different belts.1999 Mitsubishi diamante 6cyc

not told correctly at all !

• starter motor (cranking) is dead silent or clicks or only its relay clicks?
• or (i will answer for ned one here ,only, the hard one.!)
  
• start motor spins fast and the engine cranks fast but the engine does not start or starts and stalls in 2second flat.?

sorry cant see your car fail or hear it fail. not me, and MATTERS
the service manual covers that, SURE does.
even some sensors must be gapped to work installed
so guessing CKP bad, can now by 2 problems just throwing it in
and not reading the service manual first
but wait you forgot to scan it first the PCM so work blind, really?
the PCm scans will show P03xx codes that state CMP or CKP fails
not looking first is why you failed, even using wrong new parts
and what V6 IS THERE. 2.7L IT IS, USA CARS , I only do USA.
DTC P0335, is ckp bad, crank sensor and if replace not it is bad again. learn to SCAN first and not add bad parts over good. ok?
335 error page shows Out of allowable air gap
I looked at new sensors and they are not the tunable kind.

the internet is full to the max with no starts and ckp sensor swaps guessing and 99% fail.
well guessing does that. as does most have bad cam belt. oops.\
we even see barking up wrong tree, starter dead CKP swaps
now car has 2 bad problems. and wrong sensor put it .
now this V6 is hybrid cam drive engine, 2 cams each head are chain drive but the cams down are belt
and the belt fails at 60k to 100k miles and now is TIMED wrong
the PCM sees that gross ERROR and cuts SPARK dead.
and DTC for CKP AND CMP not in SYNC errors due to the silly $30 belt died, as ALL DO and soon.

the bad belt is here
see clearly goes inside engine this is not and accessory drive belt
it is for the 4 cams here.

xxxxxx,
iit must be timed correctly or engine will not run or bends valves.

Jamie, Is or was engine light on, are there any codes, was there any recent work done? The more info. the easier to help diagnose.
Removing the oil fill cap and have a helper crank the engine, while you look for cam movement,if you have cam movement that's good.
Next squirt some starter fluid in throttle body and try starting, try a couple times. If starts and revs fine while running on starter fluid, problem is a faulty fuel pump filter,fuse, relay or pump.
If it spits sputters or backfire while trying to start, timing belt has slipped probably and needs replaced.

you meant, car will not run right (unsaid)
so i unplugged the MAP sensor (forcing limp home mode)
when was last time car had fresh fuel.
when was last time car was a daily driver?> last week, last year?
by removing the map the limphome goes huge rich state.
so id say , the engine is in a very lean state and going to limphome
hides this situation.
why not post full symptoms , with all parts back on engine.
did do the 60k mile , tune up yet? if the cam belt snaps, say good by to a good engine. (boom) Timing belt, sparks and filters.?
1: cranks ok.?
2: wont start
3: is it flooding? or starving for fuel. spark plug tips dry or wet.
if spark is good all cylinders, (no engine option stated) then
i check timing, if off the belt (cam) slipped.
if the engine is flooding i do the flooding tests.
if its to lean i do the lean tests.
ASK .
for the lean test i check the ECT , then fuel pressure.
the fuel pressure is 10 tests on a V6.
I can also test the MAP in 5min with a voltmeter, to see if its right.

here is the list ,
Good voltage 12vdc to the EFI starting and running.
Good engine, spec compression,
good spark and timed correctly if, off its the cam belt slipped,
good fueling,
there are simple tests for each.
i also make sure the EGR is not stuck open on all cars with this.
and that the ISC is not dead.(stuck and dirty)

Head lights work , parked, and are not dim.
i turn key, the dash warning lamps all glow for the lamp test
this is a must, do they>? and the CEL glows, IT MUST.
if all that works
we then turn the key to start. and the starter motor cranks fast
and Sounds normal for starter. does it.
the the engine fails to start, and sustain running. right>?
all the above true?
we then check for lost spark. (with a dream of engine good..bla bla0
it is good, on all cylinders. but i check spark timing cranking and
its bad, cam has lost time , cam belt or chain, im too lazy to look up.
spark timing is good.
so i check spark plugs tips.
oops , owner skipped the mandatory 60,000 mile tune up. they are at
END OF LIFE.
new sparks and it still wont start. sparks good. sparks dry. not floodihng
so i try TEST FUEL, i spray some in the plenum or intake.
and bam it runs for 3 seconds and stops, good ,this proves
engine is good, and spark is good.
just lost fuel.
so , can you get this far?
if yes, we can work lost fuel or flood, never of which i can predict.
ask

That could be any number of things. Is it out of gas? Does it have spark at the spark plugs? You need to check a few things to find out if it is a fuel problem or ignition problem....Depending on the year, make, and model, it is possible that you could also have something like a broken timing belt. Much more information is needed to help you with this problem.

ALWAYS START WITH CHECKING FLUID LEVELS AND CONDITIONS.THIS ENGINE SHOULD BE A NISSAN BUILT V6 OVERHEAD CAM DRIVEN BY A TIMING BELT.ENGINE BEARING FAILURE NOISES USUALLY INCREASE WITH ENGINE RPM.IF STARTED IS SUSPECT THEN FIND SOME MEANS OF ROTATING ENGINE AT FRONT CRANK PULLEY,GRABBING LOWER PULLEY BY HAND AND TURNING OR SOCKET ON CRANK PULLEY CENTER RETAINING BOLT.IF ENGINE CAN BE TURNED IN THIS MANNER THEN THERE IS MOST LIKELY AN INTERNAL ENGINE FAILURE.IF IT DOES TURN OVER THEN LOOK CLOSELY AT STARTER OPERATION.

Hello, I have read about the Keyways in the crank and camshafts shearing off. If you disconnect the Battery and take out a sparkplug, you can turn the engine with a breaker bar. Then put a probe into the sparkplug hole and you should be able to feel the piston coming up in the cylinder. If the piston does not move you can start disassembling the front cover to check the Keyway on the crank.

If the pistons are moving. remove a Valve cover and turn the crank while watching the Valves or cam on the topside of the engine. This will give you an indication if the Cam is not turning. It is not impossible for a Cam to snap so watch to see if all parts the entire length of the cam are turning.

Another potential problem much easier to fix is the Starter bendix. If you only hear the Starter cranking without a load, was the engine turning? The Starter gear could fail and the starter will just spin while the engine does nothing.

Would be interested in the outcome of this problem.

If you hear that the engine cranks when you try to start the car then that is good. It means that the starter is working. If the starter cranks but the engine won't start, there could be wide range of problems. Here are some of the most common:
- Problems with fuel delivery system (e.g bad fuel pump, fuel pump relay, clogged fuel screen, etc.)
- Problem with engine electronics (e.g crank sensor, cam sensor, air flow sensor, power relay, engine computer, etc.)
- Ignition system problems, especially on older vehicles with the distributor (e.g bad ignition coil, commutator, rotor, distributor cap, etc.)
- Defective ignition switch
- Problems with vehicle security system
- Internal engine problems (e.g broken timing belt or gear, low compression, etc.)

Starter turning slowly sounds like:

- bad starter, or
- bad connection to starter, or
- bad connection(s) on starter relay, or
- low charge on battery, and
- and maybe some others... but these are most likely
