starter has a bendix ,if you here a whirring noise and no crank .two poss.starter or the flywheel has teeth missing in that spot.

Sometimes the dealer writes the code down in the owners manual, so that is a good place to start. From there the next step is to call the dealership and see if they can look the code up by the vehicles VIN number. The worst case is having to remove the radio, and retrieving the actual radio serial number, sometimes the dealer needs this to get the code.

IF THE CAR WAS RUNNING YES,IT'S A FREE SPINNING ENGINE MEANING THE PISTONS WILL BE STILL MOVING WHILE THE VALVES ARE NOT.









TIM..

The problem could be the contacts in the solenoid. The starters are not that expensive but to getting to it is very extensive. It is under the intake manifold. I had been having problems with my ls 400 (1990 with 275K miles) engaging the for quit some time and milked it out as long as I could.

Since all starters drive a flywheel inside the bell housing of the transmission, it is always situated close to the engine block with its drive gear poking into the transmission itself. Look for a large assembly looking a lot like a half of a ball that is attached to the engine.
This is true on most any motor vehicle.

The sending unit is on the top of the fuel tank. You have to drop the tank from the car. The fuel sending unit is in a connector that the fuel pump is on. This will have a retaining ring that you have to remove to get to the sending unit. Once you remove the ring then the fuel pump, sending unit will come out.

Hi.

I hope this helps you.

Thanks!

check you battery and cables. if ok check for power when someone tries to start it. if you have power hit the starter with a hammer (be careful not to break the starter) and if the starter is bad it may start when hit with a hammer. if that is the case then you will need to replace the starter.

Did you check to make sure no other fuses blew? I would also check your alternator and battery to make sure you dont have an over charging alternator causing fuses to blow.

It could be a bad ignition switch or bad starter wire from the starter switch, or the PNP is not adjusted correctly:

Here are instructions on how to remove and replace the PNP, but read over it to understand how to adjust:

Maybe try to press the brake pedal and run the gear shift throughout the full range of gears while the car is on level ground, and retry the starter to see if there is a faulty PNP adjustment.

Try to start in Neutral not Park, and jiggle the gear shift back and forth to see if the PNP is not adjusted right.

Good luck on this repair.

Either your stop light fuse is blown or your brake switch is bad.

Remove the wheel and tire ***'y. remove the brake caliper to get it out of your way, then take the dust cap off the rotor where you'l find a nut with acover and a cotterpin. remove the cotter pin, nut coverand loosen the nut, the rotor will come off. the outer bearing will immediately come out if ti's not buried into the race. Remove the inner bearing by knocking out the which you'll need to replace as well. actually to do the job right , replace both races, bearings and the seals. the races and bearings have to wear together and using new bearings on old races is just asking for trouble soon, as they do not wear together like they should. Pack bearings with new grease, install the new races, put some extra grease inside the rotor so the bearings and races will have plenty of lube, install the inner bearing then the seal, put the rotor on the spindle, install the outer bearing nuut, tighten the outer nut just until the rotor rotates one to two revolutions when spinning freehand andinstall the nut cover and the cotter pin, caliper wheel and tire, you're finished, good luck.
