Good day,

Since a while now (3 years) I have my 146 (1.6 TS 16v 1998) in my garage.
Every couple of months I would start the engine and it was running fine.
Though last times it was strangly running at high revs at idle.
Meanwhile battery went dead.
The other day the engine would not start. Not even with a new battery.
Now that I want to use the car again?!?

Could the ECU be corrupted or does it need battery-load (connect battery for some time) to feed its circuits again?
Is there a procedure to test?
I do not have a ODB or other diagnostic tool. Though like to find out my self a bit before I go to Alfa Romeo dealer.

Or could it be something else??

Suggestions and advice very much welcome.

Thanks.

i think you need to get the engine started first !
i would get a 2nd car with some heavy duty jump leads with the 2nd car reeving high when stating your car so you car keep the car turning over high
and have you tried to reset the fuel cutoff switch ?

Hi,
Had some time again to look into my problem.
Thanks for the reply earlier.

Meanwhile:
Renewed battery (60 Ah).
Cleaned spark plugs. They were wet, are used/ worn, but mounted then back.
Ignition leads checked, can be used again.
Fuel goes to engine and leaves fuel rail back to tank nicely. So fuel switch still working, including pump.
Induction voltage to injection coils can be measured while starting engine.
Fuel injector receives signal if ignition is turned on.
Got the engine running, but on ether/ mult-cleaner only.
Engine dies as soon as there is nothing of this light fuel in air inlet.
Throttling does not help,

Could it be the BDP sensor??
EG: air + fuel + injection are available. Seems to me that ECU does not see engien running and is not allowing fuel to be injected.

Am I thinking in the correct direction??
As these are rather expensive: how to test?
Think it is the sensor at the rear of engine and at the back.
Where to apply my leads of multi meter. Just disconnect and with multi meter on AC measure on the leads of the sensor??

Thanks for your answers in advance,

Greetz
