Intermittent Starting Problems

[T73]

Let me preface my post with the fact that I live and work in Senegal, West Africa -- where I have yet to find a mechanic who I have confidence in. This has made me see the importance of trying to figure out the problem on my own.

My Toyota Avensis 2000 2.0TD has been a great car. But the last 3 months there have been problems when trying to start the engine. It will always start up right away first thing in the morning. But if you go in to town and it sits for a couple of hours and you go to try and start it again --- it sometimes just keeps turning over but never igniting. Eventually the Battery doesn't have enough power to turn the engine over.

One thing that has always worked if the engine keeps turning over but not igniting is to give the car a push in 2nd gear and pop the clutch --- it starts right away.

So --- what could be the problem? Fuel line? Battery? Relay? Any advice on how to start troubleshooting this?

Thanks,

Dan

Igor the old TD engine does not have the SCV.

your problem lies with, check in this order

check Battery to body earth

check body to engine earth

check body to gearbox earth

(remake if necessary)

Check glow plugs

Check starter motor

check Battery

check injectors

check engine compression.

mostlikey the fault will be startermotor

[T73]

How do you check Battery to body earth? and body to engine earth?

[T73]

and body to gearbox earth?

I have a multimeter --- can I check the earth on these using a multimeter?

[cmia]

inspect them,

If connectors are coroded or damaged,

disconnect Battery

clean and replace.

If you cant find the existing wiring,

Just get some

8awg or 4 awg and make a new earthing kit.

Batt to body

body to engine

gearbox to engine

gearbox to body.

Igor the old TD engine does not have the SCV.

but who is responsible to stop the engine then after it has been started, then?

cheers

[T73]

How do I check body to engine? Gearbox to engine?

unless I am wrong

The TD engine has a mechanical timed diesel pump, but had a electronic govner.

The SCV on the new D4D engine is the govner on the old TD engine.

even I am confused now!

Igor, correct me if I am thinking wrong

I'l try to!

hello again

the main task of SCV is enabling to start and stop the engine -- that's

it's understood the engine heats all located under the bonnet and SCV -- whose internal copper wings resistance is variable depending on surrounding temp. it's also understood each coil has own fate/lifetime and sometimes when its service time is about to be finished -- this SCV starts to play especially when heated. I ve had an old ford sierra 2,3 diesel and experienced the same issue unless have changed SCV. may be this will show the way to an author.Cheers/Igor

[T73]

Thanks for are of you help so far --- but what is an SCV? How much does it cost to replace?

I just noticed that the starter relay may not be working. The car would not start --- so I took out the starter relay --- and it still struggled (as it often does) and then started (without the starter relay). So does this mean the the starter relay needs to be replaced? I think so.

Thanks,

If you took the relay out,

the car should not have cranked!

did you take the right one out?

i liked an old relays thanks to it can be opened and serviced. but what kind of relay is installed now and whether it can be opened ????

[T73]

You are right --- I didn't take the right one out --- when I took the right relay out the car did not crank.

So what is the SCV?

hi matey

SCV -- suction control valve or solenoid control valve

this valve is normally open type -- meaning -- when it is screwed in the pump body -- the fuel line is cut off by this valve stem and when you switch ignition ON this valve solenoid remains under voltage creating a stem lifting force opening fuel line and finally enabling pump to suct diesel in before delivery/injection. Investigate carefully the pump ; coming fuel lines with filter - the correct position of this SCV is on the pump, but all positionning variations might be available. but you should know the main task.

[T73]

This is a stupid question --- but where is the fuel pump located on the Avensis 2000?

please send the good photo of engine compartment to point you on.

So here are some photos of my engine.

Here is another picture of engine

[igormus]

Here is another picture of engine

please type her VIN code

cheers

[T73]

VIN/Frame # 53CBN0 0E047767

Here is a picture of the Battery --- which I am not sure about the wiring a mechanic did for some foglights

[T73]

If I remember correctly --- the intermitant starting problems started when I had these foglights wired to the Battery by some guy here. -- Precision work is not highly valued here --- can you see any potential problems with the Battery photo I just sent?

[igormus]

Here is another picture of engine

two questions, please

- whether VIN has been written in full and correctly ??? the program does not recognize this VIN;

- now look at the lid of the pump -- you will find several wire connections. one of the bases must be SCV that is in question. Check and clean all connections using fast solvent (wire/varnish friendly). look at this link --http://www.toyotaownersclub.com/forums/index.php?showtopic=87986 --- this is for SCV (our ravers section) -- the idea is very similar even the pump of yours is an old. Investigate the pump from alll sides and find this SCV. All connections must be as clean as possible to prevent an electricity leak.

the same is for Battery, as well
