What makes the fuel pump not kick on on a 92 Oldsmobile Cutlass


There is a red wire close to the battery in the front. It's not connected to anything. Apply positive voltage and that will run your pump for testing purposes.

How do you change the spark plugs on a 1993 oldsmobile cutlass supreme


Your Cutlass is either the 3.1 V6 or the 3400 Dual Overhead 24 valve V6...each motor is clearly marked on top of the engine plenum. If you have not changed the plugs yet...I recomend you do that at the same time...you can purchase inexpensive replacement wires with a limited lifetime warranty...be sure to compare. No special tools needed to switch out the plug wires...I highly recomend using plug wire boot lube grease to assure good clean water proof contact...also helps ease od service later as needed. The lube is only a couple of bucks...Be sure to ask the parts person the ignition firing order...this will help to confirm proper installation...Remove only one wire at a time...this insures you maintain the current firing order...remove and replace only ONE wire at a time...disconnect from the plug, then trace to the coil pack, and disconnect...replace with similar length wire using lube grease on both end connections...Plug wires and plugs should be replaced on your Cutlass OBD I motor by 100,000 miles...they can wear out and leak or misfire prior to that...Your motor is also sensitive to a clean Idle Air Control valve...about $35. or try to clean the old one and mounting hole with injector spray cleaner and wipe out...Also check for any vacumn leaks while changing wires...the old rubber lines and connections crack and leak with age...The Cutlass is usally a reliable long term car...Good luck with yours. Hope this helps.

Change rear spark plugs 1994 cutlass supreme 3.4


If you got small hands and long arms, you can change the rear spark plugs with the right extensions and swivel spark plug socket. You can get to all three from the top and leaned over the passenger side of the car.
If you need more room, your going to have to tilt the engine forward. Here is how it's done, with the transmission in park and parking brakes on with a block at the BACK wheels. Undo the two dog bone motor mount at the front of the engine, once disconnected with a friend.
Push the car forward once your release the parking brakes, push it just far enough that you tilt the engine forward and not in to the radiator. Once that is done, put on parking brakes and place block at the BACK wheels again, so we don't lose an arm.
This should give you more room to get to the rear spark plugs and yes everything is done by touch to get the plugs out and most likely your going to have to replace the spark plug wires. The old ones will be harder to remove then the front ones and a spark plug wire pliers will works best to removing them.
Thank you for using fixy and be safe, after spark plugs replaced, just reinstall everything the revers.

Hi, first there is either 1 or 2 engine struts attached between the radiator and the engine. disconnect them at the engine and reinsert the bolts into the strut then standing in front of car either push or pull the car by hand to make engine lean towards radiator just enough to catch a tab located on the engine strut mount to hold the engine away from the firewall with plenty of room to access the sparkplugs.

Timing marks for 3.4 v6 1995 olds cutlass supreme


It doesn't have any marks. Make your own before you remove the belt. If the belt was broke or you already removed the belt then you will have to remove the valve covers and install specialty tools into the ends of the camshafts to line everything up correctly.
