Fuel + Air + Compression + Spark = Non-working engine??
Okay I'm still having troubles with my car starting after my EA rebuild. The primary problem was that there was no petrol, as the fuel guage decided to be dodgy and show half a tank when it was completely empty. Fixed that problem, put in 10 Litres of fuel, new fuel filter and checked the flow again. The fuel injectors are all working as I have taken the fuel rail off to see if they were all firing which they were.
Checked the compression of the cylinders and they all came out fine. There are no blockages in the air intake as I have taken the intake tube off completely. Double checked the timing again, and adjusted the distributor accordingly. Was getting spark from spark plug lead number 1 before adjusting timing, but will test it again tommorow and will check all other leads.
Spark plugs are brand new, and I have cleaned the petrol off them before trying to start the motor again.
The shitty thing is, that last week when I started it before the car ran out of petrol the motor ran perfectly and would start everytime with a single key turn. Now the bloody thing doesn't even sound like it's trying to start, it just keeps turning over continously without firing, not even a splutter or any sign of life!
There is only 3 other reasons I canthink that it won't start, either the exhaust is blocked, the intake manifold is getting blowback through it or what I think is most likely is that the fuel injectors aren't firing the petrol in at the right time.
Does anyone know what controls when the fuel injectors fire the petrol into the motor? Is when the injectors need to fire detected by the TFI module? And could the ECU affect the the injectors as well?
The ECU has come up with no errors either, even though it has been disconnected from the battery for hours and I thought would have shown a "relearning" code.
Sorry for the long post, but I really need some help with this... I'm just about to go the extremes and get a mechanic to finish my project if I can't work it out soon!
