 Hi

I’m hoping for some advice on a problem with the monopoint throttle body. Engine fires up and then dies instantly. When I restart the same problem. The rubber throttle body mount (gasket) split and the running problem started after replacing the rubber mount. I’ve cleaned the throttle body and replaced the air idle switch. Is it likely the monopoint fuel injector is faulty and is causing the problem or is it possibly something else? (I’m wonderingif it is possible to test the injector before tracking down a replacement?). Fuel is getting through when turning over the engine with the starter motor.

Any advice greatly appreciated.
Thankyou

It sounds like you may not have plugged something back in or even the plugs connected to the wrong sensor?

If definitely sounds like it is not it is not reading a vital sensor reading or an actuator is also unplugged

Thankyou I’ll check all the connections.

Checked all connections all good. Thinking it might be the acclerator sensor?

Hi again 

I changed the accelerator switch ECU and the car now runs for about a minute. Engine shuts off with a few misfires then won’t start for a couple of minutes. Restarts runs for a minute misfires and shuts down again. Any ideas on what’s causing this. 
 

Thankyou
