Need help with 97 Suburban
My parents have a 1997 Suburban 1500 with the 5.7 350. Last week, the 02 sensor went out and they also had the fuel injectors cleaned and the throttle body serviced. They also had a fuel filter sitting around which got put on too at the same time. When we got it back, it drove fine for about 4 days or so. Yesterday morning, it was driven about 10 miles then parked for about 7 or 8 hours. Yesterday evening, it wouldn't crank and still won't. The starter whines and whines but the motor won't turn over. While sitting there, the fuel pump actuator was replaced but to no avail. What is the problem with it? There's not many places open on Saturday's to take it. I posted in both forums so maybe I'll get a few responses pretty quick. Thanks for the help guys...it's needed on this one.

The truck's got 160K, but the starter is good. When I said it whines, I meant that it's turning the motor over and over, but the motor isn't cranking. It's like it isn't getting gas. I guess I wasn't clear enough on that.

How's the fuel pressure? Even though the TBI is a low-pressure injection system, it still needs the right amount.

Could be the ECM...control module in the distributor and/or the fuel pump, as mentioned above.
Edit...oops meant Ignition Module...had a brain cramp

Check for fuel pump whine when you turn the key on.
You should be able to hear the pump standing near the left rear....if no, smack the tank a couple times and see if it'll come on. Replacing my integral pump a few years ago set me back 450.00....if there is a next time, I think I'll just install an external pump.

No I can't hear the fuel pump come on. I tried hitting the bottom of the tank trick, but I still can't get it to come on. I'm guessing it probably is the fuel pump...hopefully, a wire going to it, but owning a 'Vette has taught me that the easy way will NEVER happen.
