Where can I get the wiring diagram for a 1998 Buck LaSabre? I am interested in the part on the ignition switch/starter motor area (where I am having problems) Thanks! When I turn the key to Start, the starter motor does not turn over, but if I jump the heavy yellow and purple wires, it does. If it does start, it almost immediately dies as if the fuel pump were then shut off. All relays and fuses are ok. Battery fully charged.

I have a 1998 buick regal that has 2 thick wires hanging. They are now extremely tore and my car won't start. All outside lights and windshield wipers works. About a month ago I gave someone a jump and my window radio and inside light's stop working. I need help dont know where to start.

Key wont start car ,jump starter run briefly then shuts off fuses under hood are good ,looking for starter relay

Starter enable relay is under the hood in a fuse box that runs along the bottom of the windshield wipers, there are (2) twist knobs and (1) wing nut in the far left hand corner of the fuse box cover. remove cover. now you will see a group of smaller fuse box remove covers and look inside there will be I.D. to tell you which is which.

Looking at the end of the solenoid on top of the starter, the battery cable hooks to the larger stud on the top "12 o'clock". A smaller purple wire connects to the smaller terminal at 3 o'clock and the stud at 6 o'clock connects to the flat wire coming out of the starter. The purple wire comes from the neutral/park safety switch, which is fed by a yellow wire coming from the start relay which is fed by a yellow wire coming from the ignition. The start relay is also controlled by the Pass Key decoder module. Hope this helps, as for starters.
Check the fuel pump relay

The fuel pump relay is located to the right of the glove box.

Remove three 8mm screws (along the front edge) and a wingnut (drivers side near the accelerator) to loosen the insulation panel. Twist out the light courtesy light and using a pair of pliers squeeze the plastic nipple to remove the SIR. Remove the insulation panel from the vehicle.

After the insulation panel is removed, the fuse/relay panel will be to the right of the glove box. The insulation panel should have a diagram of the fuse/relay panel layout.

The relay should be in the left column of relays just above the fuses.
