Hi,
The ECU is located beneath the steering wheel on the left hand side , under the dashboard. You can open the screws and take it out to check.
Thankyou

I think that the ECU (computer module) is located inside the motor compartment, on the left front corner of engine compartment

It keeps stalling and won't keep running after the


Check the egr valve by located it and the vacuum hose connected to it. pull of the hose and check it for wear like cracks or hardening of the rubber. If it looks ok, reconnect it to the egr and start the engine while it is cold and with the engine idling, remove the hose from egr valve. If the engine sputters and then dies, pull off the vacuum hose one more time and try to start the car. If it runs fine with the hose disconnected, replace the egr valve.

1992 pontiac boneville, keeps stalling


Have you chg.fuel filter and had a fuel pressure test done? Does it have spark after it stalls? Fuel pumps are a common problem, they work when cold get warmed up they quit, after a while quit all together. Do the fuel pressure test.

1997 Bonneville stalls and dies on the road


Shell has had issues with contaminated fuel in the past cant recall what it was but it actually damaged the fuel pump. I hope thats not the issue here can get costly in some cases fuel pumps on GM are a whole assembly. DOes the gas gauge still read properly? This was a big tell with the contamination last time. Gauge would read empty even when full.

95 dakota dies when warmed up


yes it can but you may have a coolant temp sensor acting up which causes the computer to open the injectors to much which can also cause this 02 sensor code. when it stalls do u have spark and fuel pressure.

1995 pontiac bonneville stalls


I just went through lots of troubleshooting and expense on my 1996. Whenever I would lift my foot off the accelerator and was below about 30 mph, the rpm's would starts jumping around and sometimes it would stall. If I gave it a little gas (accelerator), I could sometimes keep it running. It also backfired once in a while. Starts right back up. Also, if I let it idle while in part, it would die after 1-2 minutes.

I ended up finding a hole in the fuel regulator. About a ~$70 part if you get an AC Delco, but very simple to change.
