Grounds are located on the passenger side cam covers (brown wires with bolts into the cam covers)
Computer grounds are located in the passenger footwell above the Central fuse panel.

Normally, the L-Jet computer is very stable and is not the normal cause of failure, however IIRC the ground for the injector relay gets that ground through the L-Jet computer. At least in the later cars, the lack of that ground is a beginning stage of that computer failure. I don't know that to be the case for the L-jet, but you might keep it in mind and test the L-Jet by asking a friend to install your L-Jet computer into their running car to test it.
