Problem starting

Post by JILLYPIPS »

Hi all
Couple of days ago my 2002 plate wouldn't start. Found out the pipe that goes to fuel filter had come off. Easy fix just clicked back into place. This is where the problem starts, since then the car starts first time from cold but from hot or within an hour of turning off it turns over but won't fire up. Any suggestions

You haven't said which engine you have (there are four possibilities).

My first stab would be the inlet air temperature sensor or the coolant temperature sensor.

Hi it's 2.0 L
Could changing the petrol pump have caused this or is it coincidence?

I can't see a connection between the pump and the engine temperature.

Hi Ian
Where would I find the air intake sensor?

I'm not familiar with this engine, but I think Item 7 is the coolant temp. sensor, Item 12 is the inlet air temp. sensor, and Item 10 is the air pressure sensor. EDIT - corrected in next-but-one post.

If you want to know which part numbers apply to your engine (Items 7 and 12), post the last eight digits of your VIN, and I should be able to tell you.

I've done some research, and Item 7 is the Coolant Temperature sensor, Item 8 is the Manifold Pressure Sensor, Item 10 is the Camshaft Position Sensor and Item 12 is the Inlet Air Temperature Sensor.

It is possible that any of these is defective and supplying inaccurate data when hot. I would suggest trying in this order: 10, 8, 12, 7.

Crank position sensor can cause hot start issues without throwing up a fault

When requesting help of a technical nature, please give as much detail of the fault as possible along with details of exact model, engine size & type, gearbox, year, mileage, and any relevant work carried out to try to solve the problem to help us help you.
Better still, put the details in your signature.

Hi
Another thing is the starter motor clicking when hot?
Only if the starter motor clicks when trying to start , and when cools down it starts then its because the starter is on its way out.
When you are starting the car and say your waiting to get up to temperature there is no air circulation around the starter motor the coil windings break down. so when the coil cools down the ohms can travel to the solenoid..
This Happened to me..

I think you mean current can flow. i.e. amps.

Anyway, Jilly says "it turns over but won't fire up", so it's not that.

Hi all thanks for your response
Looks like I'll be working my way through sensors
Will update when sorted

Quick update
We changed the crank position sensor as this seemed to be the most logical place to start. It solved the cutting out when idling problem but not the lack of starting when hot
Turns out the new fuel pump was faulty so replaced it and touch wood we're all good
Thank you again for all advice

That is quite a surprise. Why a defective fuel pump would allow starting when cold, but prevent it when hot is beyond my ken.

The engine needs a richer mixture, i.e. more fuel, when cold......
