Thread: car want start ecu maybe?

still no closer to figuring out wot the f...s up with the car but did a compression test and heres the results 1. 210 2. 210 3. 210 4. 210 think that means there all ok seeing there all the same (not sure wot they should be ????) so happy there the same but still no closer to fixing the prob

The crank sensor output is used by the ECU to time the ignition and fuelling. If there is spark and injector drive then the crank sensor must be working. If the fuel pump failed to run while cranking the engine on the starter motor the engine would attempt to fire on the small residual fuel pressure present from when the pump primed the system. The ECU conectors are pretty robust and rarely cause an intermittent connection, the problems...

coil packs.................. 1&4 2&3 it's a waste spark system these go to the cylinder order of 1 2 3 4, no 1 drivers side/cam-belt side. in the waste spark system each plug fires twice on the four strokes, hence how opposite cylinders are paired together.

for the engine to run you need fuel, compression and spark, a lack of any these three commodities and the engine will not run, You need to disconnect the fuel pipe at the release coupling by the injectors and turn on ignition to see if fuel is there, remove and check all the spark plugs individually to make sure they are all sparking, at the same time do a compression test on all four cylinders to se if there is any fault there.

Have you cleaned the crank position sensor ? Have you tried to tow start it?

If you're plugs are wet and its sparking, it might just be flooded. Mine always flooded when I was using my old leads. How old are your leads? As long as your battery is fully charged, you could try taking the plug off the bottom of the fuel cut off switch (its on the left side of the engine bay, on the bulkhead, next to the bonnet open switch) and crank it over for a bit, and see if it eventually fires once some fuel has been pumped out...
