87 Suburban won't turn over/start. Any common problems I should look for?
Hello all,
I have a 1987 R20 Suburban. Last night I moved my truck from a parking spot about 100 yards and turned it off. About an hour later went to leave, and when I turned the key nothing happened. All the lights are lit up bright but the truck won't turn over or make any type of noise. Lucky for me I work at a car dealership in the service dept. and the truck acted up at work. Just seeing if there are any common things to check first so I can point my techs in the right direction. Thanks in advance!

Ok update:
After the starter was replaced, when I pulled the truck out of the shop and started driving forward, I heard a loud knocking noise that increased in frequency when the rpms went up. Because it was so late, I left it at work and we are supposed to check it out on Monday. Any ideas or common things to look for? Thanks in advance Posted via Mobile Device

My 88 R20 454 does the same thing. From others that have had the same problem its a common occurrence on the 454, due to the exhaust coming so close to the starter. The solenoid over heats and won't allow the starter to turn over until it cools off completely. Some possible solutions are:
1) Replace the starter make sure that the new starter has a heat shield. 2) Take Turbo heat tape and wrap the starter and/or battery cables. 3) Replace with a high torque starter with adjustable index that allows you to position the solenoid in a different location. Just some things to possibly stop this from happening again if you have to replace the starter anyway. |
