Remove the ignition module retaining ring. Pull the ignition barrel out. Remove the wiring harness from the back of the ignition barrel. Reverse the process to install the new ignition module.
When an anti theft system light comes on while driving a 98 Chevy Malibu, the problem is usually caused by the Security Module. The security module is part of the Ignition Lock Module.
Ignition module bad.
I did it on a 98 Malibu by buying a remote starter and having it installed at car toys.
under the coil pack or on the distrbutor
How do I replace ignition wires on my 98 Mazda 626 2.0L
The engine computer is located on the passenger side of the firewall.
Its on the top of the engine at the right front... coils and ignition module are together. Follow the plug wires, away from the spark plugs, where they will connect into the coil pack. The ignition module is sandwiched under the coil pack. To remove either... remove the three nuts under the ignition module and the six torx screws on top of the coil pack.... voila. After market new modules (10/2010) cost $98-134 at Carquest Auto Parts. OEM Delco module cost New from B&B Auto parts $ 360 Good Luck
No i have a 2002 malibu that had the same problem when i checked it was the park lock switch that was causing it
98 expedition
this site is great
about $1.50 if you have a spare key that they can cut a new one off of.
Go to the junkyard and ask them for the part you need and have them look it up in the hollander book to see what other cars that have the same part that will fit your malibu.
