So you were really careful when you pulled your plug wires off, and you still managed to get the order wrong. How you can start over and get the wiring order correct for your 5-cylinder Eurovan? By using the pictures above. The number 1 cylinder is the that is nearest the Timing belt end of the engine and then numbered from left to right 1 through 5. Now just find the notch in the distributor housing and work counter clockwise from there: 1-2-4-5-3 That is the correct firing order and wire order. Let me know if this helps you.
