Possible faulty coolant temp sensor

How about something more basic like a tired battery ?

roadkill

1st in best served!

is the problem solved? am curious to find out. similar symptom to my v9

[subiesti]

have been too busy but think that it is the battery cause all the cars that we have owned do this after 3 to 4 years of age and if its 0 degrees outside its a lot harder to start. Has ur car had a new battery yet? 8)

[embai]

Not yet, still on the original one that came with the car when new , might be on its way out, seems to start fine during summer. Does your cranking become slower making it hard to fire up with the colder weather out there?

550cca...no problems then!

Mine starts mint everytime. A good battery solves alot of problems.

[subiesti]

yep mine slows down alot when cold think i have ta get new battery before we get -10 degree frosts otherwise it will stay in the shed 4 winter. and i want to do some driving in the snow. So batteries only designed to last 5 years normally even big tractor battories 8)

[Swindog]

I got my 550cca one for the same price as a 320cca one. Has a big reserve on it so its good for the sounds when im waiting for clients to turn up.

[subiesti]

that sounds great i want it to be able to run subs and all that so 550cca sounds the pick cool thankyou 4 ur help 8)

[embai]

a small update... i just got a new 550cca battery for my v9, still the same but do notice it does crank really strong due to the new battery... another thing i found is each time i disconnect the battery, reconnect them, starting the car up will be instant none of that cranking then start ... ???

Glow Plugs :)

I would guess at battery as well

cold weather all ways will show this up

try jumping it of another vehicle if it start better then yes battery

(My landcruiser has 1500cca of starting :) )

Got any reccomendations on brand of battery to go for? My one's almost shagged and my car has been a bit sluggish...

[Guest the_return_of_the_jedi]

if u want a decent battery you be lookin at $100+ make sure you get a 12 month warranty as well

[Swindog]

Just get high ccas. A heavy duty no less than 350cca will do you for awhile. Mine has a 550cca with a 90min reserve. Cant remember what brand. Cost me $130.

Think its a champion. The GTB has a repco heavy duty in it with 330-340ccas.

[Guest]

ECU start proceedure, = coolant temp and crank signal, no other sensor is used for initial fire up

possible system is logging codes, and you disconnecting battery is clearing codes and allowing start straight away

get dealer to check codes and temp sensor calibration alignment

[embai]

how much do dealer normally charge for checking codes and if this is the problem how much you think it will cost to fix thanx

[Guest]

prob around $30 to check codes

Temp sensor around the $80 mark plus fitting

Crank sensor around $120 plus fitting

Costs are from memory, call a dealer and ask

make sure battery is all good and terminals are well secured too

[embai]

battery are brand new, terminal are definitely secure

i get them to check for the codes

crank sensor are easy to change,

coolant temp sensor <--- do i have to drain the coolant?

so i assume the price for both sensor are pretty cheap

I bet on Marshall/exide,This comes from 20 years of diesel experiance

I would suggest a NS70 (or NS70L I cant remeber which way around the terminals fit)

It is the biggest battery that barely fits in the hole

[embai]

update = have scan for DTC codes and came back everything was fine, no pending codes either... ???
