Initial Test

WARNING: This page is about a different car, the 1994 Mazda Navajo and 1994 Mazda B4000. However, it is still accessible from the selected car via links, so may be relevant.

Check for any stored trouble codes and repair as necessary. See appropriate G - TESTS W/ CODES article in the ENGINE PERFORMANCE section below. Using a high-output spark plug tester, check for spark at all spark plugs. If spark is present at ALL spark plugs, go to CHECK PROFILE IGNITION PICKUP (PIP) AT ICM. If no spark is indicated or spark only occurs at some spark plugs, go to CHECKING PLUGS & WIRES.
