hot starting problem

(1/1)

JIMBOBLY:
ive had this hot starting problem for a while,ive fitted plugs,leads,cap and rotor arm and coil and module,and still no cure,lolit starts fine cold,but if you go a few miles,then go to restart it,it will wind over n over,if you back off the key,as soon as you hit the key again,it fires up,cough a nd a pop smelling very rich,then its fine,i thought to much draw from a knackerd starter,but that would do it when its cold i'd of thought,what do you think?any help is always much appreciated,jim.

Rossko:
Let's guess its a petrol V8 ... but carbs? EFI, hot wire or flapper?

Rainbird:
If it's the one in your avatar, then I'm thinking 3.9 hot wire EFi.  Have you checked the temperature sensors?  There are two; the easy one to get to is the sender for the temperature gauge and the other nearby which is more difficult to get to is for the ECU.

I can't remember how the 3.9 cold starts.  If there's a cold start injector on the plenium, then this could be causing the problem if it's firing each time you start.  you could try disconnecting it to see if that makes a difference.  It will still start from cold without this connected

JIMBOBLY:
yeah sorry,bit stupid of me,lol,it is the one in my avatar,3.9 efi hotwire :lol:,i havnt tried the cold start injector no,but i have done both the sensors,sorry,should of mentioned that too

Range Rover Blues:
Np cold start injector in the hotwire system.  It runs rich untill it gets a reading form the MAF sensor which is why they often stall after a couple of seconds when a sensor is bust.

The Haynes manual is actually very good for testing the basic operatrion of the EFi system ;)
