Jetta 4 doesnt want to start

Post by vmanoke »

Hi guys can someone tell me, if you did the whole service, changed the petrol pump. Even the module (coil). But now the car still doesnt want to start. When i want start it, it only crank like it doesnt have fuel. And that time there is fuel.

What is it thats missing? Please help

can't remember how many times I have said this.
petrol engine requires really three things to run.
Fuel in the correct ratio
Spark at the right time
compression - which by definition includes the correct cam timing.
If all present it will run.
You are missing one or more of these.
test for spark and check timing, do a compression test and be sure fuel can reach the cylinder. Which have you tested.

Thanks guys for the efford of replying.

The problem that was causing that after checking all of car, was petrol pump and the fuel pump relay. Changed the petrol pump but still wasnt starting then took back the old one. Now its starting perfect. Thanks guys
