Engine Mechanical problem
1997 Other GMC Model C6500 V8 Two Wheel Drive Manual trans 65000 miles
The truck lacks fuel after it has been running for awhile. It will not start until it cools down. It runs for about 15-20 mins. Before stopping.
I changed the fuel pump but the problem persists. I did a little research and found that there may be a defective fuel pump relay. Can you tell me where to find this relay?
