engine wont fire

Merhaba Mehmet,

well it is the ECU that lets the fuel pump run via that relay.

Can you check on pin 19 of ECU whether it is set to ground for 2 seconds when you switch on ignition? Also whether there is 12V between pin 16 and pin 11 and pin 24 and pin 11 when you switch on ignition.

Before you do that measuring for too long: Remove pin 15 from ignition coil. Otherwise your coil and power resistors can burn.

I sent the ECU of to a Specialist AVILEC Ltd based in isle of wight
and ran a diagnostics and they said it ran 100% perfectly and it came back with all the test results which i have. I know its something simple

Merhaba Mehmet,

I never heard of Avilec and a D-Jetronic ECU is something totally different than a modern ECU. It is analogue electronics from the 60s.

If you are so sure that your ECU works. you should follow wiring diagrams and test all components and connectors there. Fuel pump must run for 2 seconds after ignition is switched ON. There are only few compoentns involved as you can see here on my D-Jetronic web site: jetronic.org/de/downloads/download/3-wir...p-control-d-jetronic

Hi Mehmet,

just for curiosity: How many function blocks did Avilec verify on your ECU? I really wonder whether they know their business or whether they just resolder everything and claim it works.

A failure of fuel pump control in ECU is something that can even happen temporarily.

hi DR-Djet
