engine keeps cranking

Post by Dmitriy Olov »

Hi everyone I have a problem with my polo classic 1999 model 1.6 engine. I just replaced new oil velve Seals, rings and bearings. the online keeps cranking. there is spark and also pulse on injectors but it won't start. it's been going on like this for a month now. when it cranks it feels like It will start but just keep on cranking.

Make sure you have the fuel supply hose on the right side of the fuel rail. Easy to swop them around.

Will it cause damage if you have them the wrong way around or just builds more pressure?

actually there will be almost no pressure in the rail. No damage to anything. Just swop them around.

When it dies is there no spark? Yes can be the coil but do the basic test to see if it sparks or not when it does not start.

It's that pickup sensor on the dizzy ,I had that issue on my g3 .. randomly stop sending spark ,check if any other cylinder is getting spark.if u mechanically inclined , remove the dizzy and rotate manually while it's plugged in and see if spark jumps to next lead .

I'm not too sure if this is going to help,but it may help isolate the issue

Uhm yeah there is no dizzy on that car. Uses 60-2 and a cam pickup in combination with a coil pack.
Yes start by swopping the coil out. I have seen 60-2 pickup die when they get hot and come back when cold but that is not really common. At thatbstage if younlook at it with vagcom you will see no rpm reported when you crank the motor.
