Car: 205 Rallye 1.9 from 1993
Engine: 102 hp 1.9 with Bosch LU-Jectronic, O2 sensor and catalyst. So basically it should be like a pre-cat 1.9 with L-Jetronic, except for the O2 sensor and catalyst. It's quite different from the Motronic on later 122 hp 1.9 GTIs with a catalyst.
Symptoms:
The car had been sitting for two weeks, but the battery had been topped up with a CTEK charger which indicated that the battery was fully charged. It started and ran fine before being parked.
* Engine cranks when the starter is activated by the ignition key, but it doesn't even cough - so no combustion taking place.
Checked:
* Spark is ok, checked visually by removing a plug and looking at the spark. Ignition coil, distributor and rotor replaced less than 3000 miles ago.
* Fuel pump running, tried loosening the hose at the top of the fuel filter. Fuel came spraying out.
* Tachiometric relay next to the ECU replaced with a new one from Hella. Old one didn't click, new one does. Makes no difference.
* Fuel injectors checked by dismounting the fuel rail and looking for signs of them squirting fuel.
And here comes the part I don't get: The injectors are not firing, when the engine is cranked by the starter no fuel is squirted from the injectors like it normally would.
Instead, when the ignition key is turned counter-clockwise and the starter is switched off the four injectors all give one simultaneous squirt of fuel.
Has any one on here experienced a similar problem, and solved it, or have any ideas as to what causes this?
