Bravada has gone haywire
97 with 107K.
Our son's Bravada was acting up, start it and drive fine but shut it off and you had to wait an hour or more before it would start again. We had had problems with a short in the past so thought that might be a possibility or that it needed a new fuel pump.
It had been starting, but only if you could hear the fuel pump come on, so we had not been driving it. Cleaned the cables and ground wires. Then it stared and ran but died and would not restart. Number 4 fuse to the guages and number 10 to the ECM ignition has no power. ECM battery has power. When this started it was draining the battery, now it isn't.
Bought a new fuel pump since it was probably time to put one in anyway and got ready to install it. We were going to pull it under a shade tree, but now it's locked in park and there is no electricity to the fuel pump at all showing on the voltage meter.
Does anyone have any idea what's going on with this vehicle?

My nephew had the same problem with a 95 blazer that had the central point injection on the vortec V6. It turned out that the injector was going bad. He had already replaced the fuel pump with no change. After changing the injector problem stopped. He found the injector on Ebay.

This is was fixed it.
Found another posting at another website for a 97 Blazer doing almost the same thing. The suggested fix was a new ignition switch. We took the new fuel pump back we had bought and got a pretty good chunk of money back and put a new switch in it. Now it's working fine, but I am waiting for some new strange glitch....all those wires to the power seats look like a accident waiting to happen.
