  3. Place suitable container under cold start injector fuel line. Cover fuel line connection with shop towel. Slowly loosen fuel line union bolt to release fuel pressure. Once fuel pressure is released, remove union bolts, gaskets and cold start injector fuel line.
  4. Remove EGR pipe retaining bolts. Remove EGR vacuum modulator from bracket. Remove retaining bolts/nuts, air intake chamber and gasket. See Figure.
  5. Remove fuel pipes from delivery pipe, fuel pressure regulator and fuel filter. Disconnect spark plug wires. Rotate crankshaft so cylinder No. 1 is at TDC of compression stroke. Ensure timing mark on crankshaft pulley aligns with "0" mark on timing belt cover.

    NOTE: If cylinder head removal is difficult, pry between cylinder head and projected area near front of cylinder block. DO NOT damage sealing surfaces on cylinder block and cylinder head.
  9. Remove No. 2 timing belt cover, delivery pipe, insulators and spacers from cylinder head. DO NOT allow injectors to fall from delivery pipe during removal.
