I have a 1994 Olds Bravada - 4.3 CPI Engine. Car won't start. I changed the Distributor cap, Rotor, Ignition coil, as well as the spark plugs. The fuel pump tested good according to my mechanic. He said he called the dealer and that it might be the ECM unit costing about $800.00. Can any body please let me know where the ECM unit might be, so I can remove it and match it up at a junk yard.

I have a 2000 Oldsmobile Bravada and it has been completely shutting off in the middle of the road without a service engine light coming on. I have replaced the fuel pump and the PTSI sensor but it still shuts off after about going the road less than a mile. What could be the problem. is it the computer telling it to stop the fuel from coming to the fuel injectors, or what is it. can anyone give me the answer?

Did you ever get any replies about the ECM on your 2000 Bravada? I've been having the same problem with the car shutting off while driving it, mostly in hot weather, but no one seems to know how to fix it. I've had 3 fuel pumps, a new radiator, a thermostat, and only my mechanic knows what all else. I was chatting with my brother yesterday and he told me to look into replacing the ECM. The car only has 68,000 miles on it, I'd like to hold onto it for a while but want to be sure about the ECM before going forward with replacing it. Any thoughts?

I too am having simular problem. In the winter time, all is dandy, but in the summer time, with 80 and 90 degree temps, I can be going along and it feels as if I am running out of gas. Pull off the side of the road, wait 15 to 20 minutes, and I can start up once again. Only problem is it keeps shutting off but only after a few miles each time after. I have checked fuel presure when it was acting up, reading 40 to 50 psi. I am thinking myself, (I am not a Mechanic) it's either the fuel pump going bad AGAIN, or the presure regulator. Reading specs on the regulator, I have found 65 PSI, and the fuel pump from 60 to 90 PSI. It actually acts like it is VAPOR LOCKING, which I have been told is impossible with fuel injection???

Hot weather and Bravadas don't get along, I just got suckered into another fuel pump two weeks ago. It took me two hours to get home from a 15 mile trip and my car actually died in front of my mechanic's station. I spoke to him about the possibility of it being the ECM but he told me that it couldn't be because when he "sprayed" the fuel pump (I have no idea what he sprayed) he said the car started right up and if it was the ECM, the car wouldn't have started, so, another freaking fuel pump and another $800.00 and I still have the problem. I've given up driving any distance in this hot weather. Have you been able to find anything out?
#9 of 271 1998 Bravada will not start

Hello all. First post here but unfortunatly it's because of a problem. I just recently bought my wife a 98 Bravada that has 110,000 miles on it and is in imaculant condition. We have only made a few short trips(less than 100 miles) and really like the vehicle. While she was running some errands she went to leave the store to go home and the truck wouldn't start. She ended up getting a ride home frome a friend. After getting off work we went to see what we could figure out thinking it may be a bad battery. Before trying to start it I checked the batt. voltage and it was 12.3 and while she tried starting it dropped to 10.1, started and ran for about 10 seconds and died. After a few more tries we pulled the battery and took it to get tested. The battery tested good and the parts guy said it may be the alternator so we went back and I pulled the alternator only to have it test good. The engine turns over strong but wont fire. Something we noticed is in the upper right of the gauge cluster is a battery icon that is lit and has not been in the past. Also when you turn the key to the run position none of the other "idiot lights" come on, Service Engine, Seat Belt icon etc. This leads me to believe its an electrical problem but where do I check? I did check the fusible link on the positive batt. terminal and it's good. All fuses under hood and on the interior fuse panel are good. One last thing that may help point me in the right direction. I was going to and roll the truck into a "better" spot in the parking lot (yes it's stranded) but when you turn the key to the run position and push on the brake it wont come out of park. Any insight or experience would be very welcome. I just hope this isn't a sign of things to come.

I've never seen an automotive forum with so little activity. On other forums I visit somone would have at least tried to help. Does the moderator have any auto experience or is this place all about checking out each others mud flaps? My problems been solved, thanks anyways.

I guess there aren't too many '98 Bravada owners who could pitch in to help. So, how did you end up solving your problem?

Spent a few hours visually inspecting and started troubleshooting with a volt meter. Bad ignition switch.
