Mazda B2600 cranks but does not start due to burnt wire from fuel pump causing coil failure on Mazda B2600

Problem overview

Some Mazda B2600 owners report experiencing starting issues, particularly when the vehicle cranks but does not start due to a burnt wire from the fuel pump, which can lead to ignition coil failure. These owners note that common causes for starting failures include a dead battery, alternator problems, or a failed starter. Additionally, a burnt wire can disrupt power distribution to the spark plugs by affecting the ignition coil. If the coil is not receiving power, some owners find that the pickup coil or optical pickup inside the distributor may be faulty. To resolve these issues, it is recommended that owners test these components with a scope, as replacing the pickup coil or optical pickup may be necessary to restore power to the ignition coil, given that the coil itself is not available separately. Proper diagnosis and prompt resolution are essential for ensuring the vehicle starts reliably.
