Drivers side

Then look for the reason there is no spark.

could be the rubber got soft on the balancer or a crank bearing

Do you have spark? No fuel pressure.

REMOVE HOSE AND UNBOLT

That would depend on where on the diff. the leak is coming from. If its leaking where the driveshaft connects to it, then it's a pinion seal. If it's leaking near the wheels, it's an axle seal, and if it's leaking where the cover is, it's a bad cover gasket. If it's the cover, you can reseal it with RTV gasket maker.

sounds like its bleeding back to the tank. try putting in a 1 way valve.

check fuses

It has 2 possible solutions 1) fuel sending unit is going bad which the tank has to be dropped to change, 2) you have a bad cluster panel. Hope this helps

yes its in the taillight itself. But before you do that check the prongs in the socket to make sure they are getting a good connection. This is a common mistake on general motors period.

I had the same problem with my 02 malibu. Most of them are located on the right side of the car, right under the dash. Most of them are very easy to swap out. When you look under the dash, you will see the compartment and should be 4 screws. take those screws out and remove the old fan. Replace it and you will be on your way. This is usually a very easy and cheap fix.

My husband had the same problem with his 1988 S10 Blazer. We drained the tranny, cleaned out the pan and put in a new filter etc. Filled with new fluid and all problems solved. Shifts better now then before the tranny service.

Checked fuses? Tail light bulbs? Brake light switch? Flasher?

Check underneath for interferences, etc. Look near the transmission. Those transfers had a bad habit of wearing our the splines. You made need a replacement.

the only way to know for sure is to test fuel pressure. The test port is on the fuel pressure line on the back side of the motor near the distributor. You should have at least 57 psi of fuel pressure. Anything less and it will not start.

If you have no fuel pressure than you'll want to check for power of the fuel pump. You should be able to find a spot where you can access the harness as close to the fuel pump as possible. You'll want to probe the large diameter grey wire. It should have power for 3-5 seconds as soon as you turn the key on and anytime the key is in the start position.

Another thing you can try is spraying a little carb spray down the throttle body. If it starts and runs than this is a classic sign of low fuel pressure. The injector poppets require high fuel pressure to open when you start the vehicle. When the vehicle is running the poppets are under vacuum and require less pressure to work.
