Title: **UPDATE** New engine - starting...but tapping
Post by: ben_91 on March 14, 2010, 08:19:53 pm
Hi all,
yet another problem for me!!
I purchased a new engine of Yoof, which there is no problem with, however the car now doesn't start?!

The engine went in in about 15 hours with no problems whatsoever, however now there is nothing when you turn the key.

The ignition comes on, lights and everything work, but only a click when you turn the key to start.

I can't even hear the fuel pump which i believe i could before!

I've checked for loose wires and earths and fuses but can't see anything amiss.


Is there anything that anyone can think of?
Are there any more fuses other than the ones in the scuttle panel?


Help much appreciated!!!

Thanks

Ben

no the starter doesn't turn, i will check the hall sender tomorrow.
Blade fuse is fine, is there any way of checking the relays?

I forgot to mention something possibly quite big, when fitting the new engine the negative terminal was touching the battery still and we did get a few sparks!

Thanks

that might've done a fuse or something.

Is the starter wired up right? spade on the right terminal? (nearest the engine)

unplug hall sender, look on the dizzy for the -, 0 and + marks.

use a screwdriver or paper clip to short out the - and 0 on the connector.

you should get fuel/spark each time you short out.

if that works, then your ecu/relays/fuse all okay, just need to plug hall sender back in and get the starter working, you should have a working engine if HT leads are on in the right order! :)

No sparks when doing that, so it's down to ecu or the relays? (i've double checked all fuses and they look ok)

Thats what i thought at first.
Starter is wired up ok - just double checked.
Are there any more fuses than them in the engine bay?

Thanks!!

10 points to Pete
connector was on the wrong terminal on starter motor - my dunce of a mate out that on and assured me it was right until i double checked it yesterday.

However, it still doesn't start,
there is no spark at any lead.

two plugs on the coil the wrong way round? dizzy died in the shake up? coil died in the shake up?

test as rae says - if still no spark then its likely the coil.  If there is then probably hall sender

Post by: ben_91 on March 16, 2010, 02:18:19 pm
yep still no spark
so likely to be the coil?
great more money :(

does the coil look like this?

or this?

generally the first is a later spec one.  If it looks like the bottom one then its probably original!

you can get pattern ones fro £20 on ebay.

it looks like the top one, however there appears to be no power coming into it through the connector?!

edit : there is power going in, just made that up!!

new coil, still no good!
there is a current coming through one of the three pins.
Is this normal or should it be through two?

have you got the earth cable connected from your engine to the body/battery, these Polo's need a good earth.
Title: Re: **UPDATE** New engine - not starting

also i have had this issue where i didn't get any spark or fuel priming and it was due to an iffy ECU chip, this might be your issue if you have shorted it out when putting the engine in however mine would crank though.

also how good is your battery?

thanks everyone, was down to the plug going to the coil and the plug that is on the metal bracket next to the coil being the wrong way round.

Next question though guys - what's is the pipe that comes from the scuttle panel but doesn't lead to anywhere?
leaking all the coolant out of there now when turned on.

Thanks again

as Pete said above - I misread it  >:(  ::)

it;s quite hidden but will do my best :)

Post by: PeteG40 on March 20, 2010, 06:43:33 pm
thats just a drain i think...  from scuttle downt he back of the inlet

if its coming from there - would suggest yr heater matrix area has a leak - bleed screw open perhpas?
Title: Re: **UPDATE** New engine - not starting
Post by: ben_91 on March 20, 2010, 06:47:21 pm
yeah that makes sense because there was a puddle in there. I presumed it was because of the rain.
Will look and see why it's leaking there now!

Cheers Pete

Post by: ben_91 on March 21, 2010, 12:31:49 pm
took it all apart and seems to be leaking from the matrix thing inside.
presume this is from me leaving it with only water in over the winter!?

Is there anyway of blocking it off so i can still use the car without the heating?

Thanks
Ben

Just join the hoses together, or connect together both stub pipes in the engine bay.
I'm not sure if the coolant valve closes both sides, or how good it seals, but maybe it'll be ok if you leave the temperature set at full cold?

Post by: ben_91 on March 23, 2010, 12:44:47 pm
Right - water leak is fixed now - only problem is it's tapping really loud!
No idea what it is as i put engine in without touching anything internal!

ideas?

Thanks
Ben

probably tappets as its been stood.  Ensure oil is at right level and give it a good run out.
Title: Re: **UPDATE** New engine - starting...but tapping
Post by: ben_91 on March 23, 2010, 01:42:04 pm
ok will do :)
Title: Re: **UPDATE** New engine - starting...but tapping

Ben- engine was on a stand for about 18 months, so the tappets will have drained down. Usually takes a few hundred miles to recharge them properly.

Only other option is to do what Pete does and keep a set in your kitchen in a bucket of oil!
