1971–1976 Oldsmobile Delta 88: Oldsmobile delta 88 Engine specifications

Guys, I hate to break it to you, but if you want this site to be useful the information you provide probably should be accurate. I'm a girl and even I noticed you have some wrong information on this page.

While technically Oldsmobile, and Chevrolet are both GM products, the 305 was a Chevy engine. 7th gen Oldsmobiles used a 307. Still very interchangeable, and quite similar, but it's not exactly the same.

Oldsmobile: Why wont my car still start?

Fri, 16 Sep 2022 08:20:29 -0700

I have a 1999 oldsmobile alero I just replaced the ecu box and ignition . The security light finally stopped blinking and the doors chime again and the trunk opens again but it still won't start. When trying to start it it does turn off like it did before switch parts now it seems like there is no gas or battery no juice but there is gas and battery good. Why won't it start still?

1989-1996 Oldsmobile Cutlass Ciera: Replace Ignition Control Module

Sun, 26 Jan 2020 23:21:05 -0700

I have a 1989 Olds Cutlass Ciera 2.5L 4cyl

After driving for 20 to 30 minutes my car will suddenly stall. I wait about 10 minutes and it'll start back up again. It runs for another 10 to 20 minutes (or 5 minutes at times) then stalls again.

I changed the fuel pump relay and that seemed to do the trick but then I didn't really drive more than quick in town trips. The first time I took it out of town on the highway it stalled 3 times. It took me an hour and a half when it usually takes half an hour at most. It stalled once on the way home. The next morning I went out to start my car and it wouldn't start. It cranks, gets fuel but just won't fire. I was told by my mechanic that it's the ignition control module. My son is going to try to fix it since my mechanic is down with the flu. We don't have a repair manual so I'm looking for some detailed instructions. Can anyone help?

Oldsmobile: 1992 98 2 cylinders not firing, even after coil pack replacement

Fri, 16 Nov 2018 06:34:43 -0700

Long story short.

I bought the car and after 2 days it developed a vibration coming from the engine.

low power, bad fuel eco, gas smell from exhaust.

replaced spark plugs and cables, didn’t help.

I took the cables off the coil packs one by one and confirmed that they would arc, 2 did, one didn’t.

So i replaced that and still nothing, It is getting power but not firing.

I’m thinking ignition control module… Am i missing something?
