Having a fueling issue at the moment. Fresh rebuild which has larger turbos, injectors etc and a running in chip programmed for the changes made.

The car is over fueling. The car starts fine first time and runs with no issues, once the car starts to get warm the car stalls and we can't restart it. There is a strong smell of fuel which you can smell from the exhaust as well. Friend spoke to John Dixon and he suggested that the fuel lines could be on the wrong way round going to the pressure reg and the damper. Checked and both were fine. Anyone have any suggestions or is anyone local that may have a fault reader that could pop down for a couple of hours or that I could borrow and test on the car please?

The car is so close to being back on the road and hoping this is a minor problem.

I have new water temp gauge sensor, water temp ecu sensor and new loom as well. Definitely seems like its running on choke lol

Brett at Custom exotics managed to connect my car up to a console of some sort to try and get to the bottom of the problems I’ve been having. Thought I would share some of the readings that were coming back hoping if anyone could help to see what’s causing this.

 

When the ignition is turned on but not started the temp reading counts up from around 17c and goes up one degree every second or so. When the car is started the engine gradually rises to around 70c-80c but then when the engine is switched off the temp drops back down to around 18c again and then car won’t start - guessing because it thinks the engine is cold and is trying to do a cold start.

 

The ECU before did give a faulty engine temp sensor which has since been replaced but the same error is still showing.

 

Does anyone have any ideas to what could be causing this?

Assume you have no warnings lit up still when engine is running?

 

Take it you have done an ECU diagnostic to look for error codes?

Yeah we done ecu diagnostics check which showed the temp sensor fault in the first place. There is no warning lights when engine is running

I would remove the temperature sensor and check the resistance both at cold and hot using a multi meter whilst the sender is immersed in hot and cold water.

20 deg' c = 2.1 / 2.9 resistance, k ohms

50 deg' c = .68 / 1.0 "

80 deg' c = .30 / .33 "

If memory serves me right.

At least you can then eliminate the sensor.

have you checked the connection to the ecu... sometimes this will cause issues particularly if not connected evenly all the way along....

Yeah thanks for the loan of it mate I think we have got to the bottom of it now it appears that somehow in the re wire the aux water temp pillar gauge has caused the prob being wired into the ecu temp sender wire it was like this prior to all the work so not sure why its caused a prob now but all is working fine with it disconnected . Onwards and upwards now Ant get steering and supension set up then run in then loads of wonga for someone to tune it all up !!!! good luck mate ...... was beginging to think it was never leaving the workshop !! evn thought Vijay would have his done 1st lol !!!

cheecky f**k! lol I'll be calling you by next week to discuss getting mine back into yours ;) So Ant, hurry up cos I need your space :D
