The 222 4v arrived on a load loader. The seller (a salvage yard) and the driver of the recovery truck both insisted that it was a runner. In fact, the driver claimed to have heard it running only the day before.
I couldn't even get the engine to crank, but Marc, who has a bit more knowledge of the immoboliser, set it to 'Valet' mode and it would then crank.
After a fair bit of unsuccessful cranking, the driver piped up that it has run out of petrol 'yesterday' so they has poured a gallon in. Thinking that it was low on fuel, I pour in another gallon or two.
Still no joy, so back to basics.
I used my Xenon 'Supastrobe' timing light to establish whether there was a spark. No spark, no go.
We eventually discovered that ther driver hadn't actually heard it running - and the man who sold it to me couldn't talk on the phone because he was in Preston!
So, we do a deal and offloaded the car.
Next day, we check the voltage at the coil (12v, good) and now we are into diagnostics.
This engine has a cam shaft position sensor and a crankshaft position sensor. Both are identical and should have a resistance of about 650 ohms when tested on a multimeter. The camshaft position sensor gave the correct reading, but the crankshaft position sensor read open circuit.
Luckily, Marc had one to hand, so this was fitted (although this was no mean feat due to seized bolts on the bracket).
Next, we checked for a spark - all good, but still no firing.
Next along the line is petrol.
A quick disconnect of the fuel line at the bulkhead connector reveled a distinct lack of fuel.
Knowing that the car had had a bit of a knock, I expected that the fuel pump cut off had activated, This is located in the top of the boot, near to the fuel flap solenoid. I pushed the reset button, but still no fuel delivery.
The fuel cut off switch has 2 wires on it, on goes to the fuel pump and the other to the fuel pump electrical feed. I wired one of these to a switched 12v and could immediately hear the fuel pump whirring.
With the the fuel lines securely reconnected, it was time for another go.
With fuel and a spark, she fired within just a few seconds and soon settled down to a smooth idle.
