Possibly yes. they are sensitive to heat. have you ever had the crank shaft pulley squeal. that too can cause it to fail.

SOURCE: coolant overflowing and now wont start

It sounds like a timing chain problem as far as the starting issue, since it's getting fuel.
As for the coolant overflow, I would remove the thermostat and see if that solves the issue and replace it regardless along with fresh antifreeze and flush.

SOURCE: Car cranks but won't start.

Could be a crankshaft position sensor fault or even a ignition coil fault. I suggest u check the stored fault codes in the PCM first. If there is no ckp sensor codes in the system and a new coil doesn't fix the problem it's possible the coil has spiked the PCM . If this is the case a new coil and PCM should be installed. The engine rpm and signal from the coil is picked up from the ckp sensor.

You are at thhe right trail what controls spark is coil pack crank sensor sparkplugs and plug wire but the most important is power . I mean 12 volt connections and ground This includes checking fuses you need a simple volt meter doesnt have to expensive or fancy just to pick up 12 volts let start with fuses in the engine juction box (there not mark to what it belongs to) make sure none are open. especially fuse 19 and 24 , next go to the crank sensor make sure the tabs are snuggly on now to the coil pack there is a red and light green wire this comes from ignition and feeds 12 volts at the coil pack measure that voltage is it 12 volts if not correct it this is from ignition switch ( you can make a tool that feed 12 volt with a wire and a fuse in series and attatch it to battery and the primary wire this is known as hot wire) next go to the ECM wiggle the wires see if that get a connection going if not go back to the ICM here are the wire you are to measure the tan light green, this is from ECM and it is pulsed it measure 5vlts to 0 volts switched then measure the tan orange the same thing 5 volts to zero,then tan white again 5vlts to zero. any one of these 5 to zero fails you fix is the ecm

99 F350 7.3 RUN 1 MIN SHUTS OFF CHANCHED FUELPUMP STILL RUNS 1 MIN SHUTOFF.

When it fails do you still have spark at the plugs? Sounds like and ignition module or coil to me.

Can anyone please tell me where the cam sensor and crankshaft sensor are located on a 2002 RAV4 2.0 D4D...116BHP Problem is wont start when engine is hot.

this a diesel. (our is 2.4Lgas(petrol)
cold starts fine,runs perfect cold RIGHT?
common rail system.

the PCM will tell you when those are bad, cranking for 5sec or running.
does your run,. ? if yes for get them. and scan engine PCM.
some sensor takes major work to reach.

get the FSM on that car. y
so get the FSM for your car, your engine and your country
The DI chapter covers this. read that yet? diagnosis?
did you use the scan tool an see what up's up or not ?


your engine really is.
1CD-FTV I4 (diesel)
that is the correct name, so study only that)

no start hot.
its too much fuel or tool little?
to little?
did you try test fuel to see if loss of fuel is the problem?
on diesel it's poor compression
or lost fuel , hot starts.
easy huh , no spark to check , there is no spark
some diesels have 1 sensor for injector timing.
if flooding , you get black smoke out the tail pipe, so id suspect
you'd have noticed that and did not see it.
test fuel, tests.
if this fails, a full hot compression test. its not the cam belt slippped
if runs ok cold,

i bet the injectors are shut down
the PCM tell you why, so let it.
SCAN it. after 5 seconds cranked.
almost all PCM report 1 bad pulse of 10 in all speed sensors.
(CKP or CMP )

The car start fine when its cold but when it gets hot it will not start agatn

Sounds like a heat related problem. When hot and not starting pull a spark plug and see if you get a spark. If not suspect a thermal induced problem with the crankshaft or camshaft position sensors. When you pull out a position sensor clean them off with a rag, sometimes metal filing are found on the sensor. If you get a spark it might be a MAF sensor. The maf measures air flow into the engine.

Hard to start at times hot or cold

engine wont start cold or hot could be fuel problem.check for fuel or spark.try doing little troubleshooting make sure sparkplugs and wires good condition.fuel filter been changed.engine need fuel and spark ignition to run.turn ignition on listen for fuel pump operation in fuel tank if no check fuel pump fuse and relay.if fuse relay okay.problem could be the fuel pump but first use code scanner look for PCM, CRANKSHAFT POSITION SENSOR,CAMSHAFT SENSOR AND DISTRIBUTOR IGNITION FAULT CODE.MAKE SURE YOU HAVE FUEL INTANK I SEEN THAT HAPPEN BEFORE.

Runs fine for approx 15 mins,then stalls out and wont start again

sounds like coil problem, coils will start cold then get hot and stop. when coil cools will crank up and run till it gets hot, try to replace the ignition coil,dont think it would be a crank sensor, try a coil,thanks robert b.
