Question about 1998 Oldsmobile 88
Where can I get this diagram?
SOURCE: My 1998 Delta 88 LS
First lets start out with finding out if its a fuel problem or electrical as in no spark. You need to pull a plug wire off and if you have a tester put it on the wire if you dont have a tester put a screw driver in the wire and place it close to metal on the engine but not touching and crank over the engine if you see spark then your good there if no spark then thats where your problem is going to be. If there was spark then squirt a shot of starting fluid into the intake or throttle body and turn over the engine if it starts then dies then fuel delivery is going to be where your problem is at.Have some one turn the ignition key to the run position dont try to start it just turn it to the run position while you listen at the gas tank remove the fuel cap and place your ear as close to it as possible and listen for the pump you should hear a humming sound for a few seconds then stop if you dont hear it it could be your fuel pump could be bad check to make sure you have voltage to your fuel pump with a tester before going through changing out the pump. I hope this helps you let me know how this turns out.
