2004 Chevy Silverado. New tires no engine work. Tried disconnecting battery.
2004 chevy Silverado 5.3 v8 starts and immediately stalls. When given gas doesn't even turn over.
Radio wont work but all dash lights work. Diagnostic tool wont read anything. But truck reads
Tried disconnecting battery did nothing. Please help. I wish I could donate but i just spent my last 11
dollars on gas so i could get friend with broken truck to work. This info is detailed enough because its
all the info he gave me. But if you need more just ask and ill ask him.
All these things may be related, or not. Be sure to check that the battery cable are tight.
For the scan tool not powering up, check the cigar lighter fuse. Is either in the underhood fuse block,
or the drivers side dash fuse block. This fuse powers the diagnostic connector under the dash.
In fact, be sure to check all fuses.
Starting then stalling could be a security system problem. The security / theft light would come on the
dash after trying to start then stall.
Fuel pressure is another thing to check.
As you can see, requires some diagnostics of these different systems to see if all related or not.
Question = I have a knocking sound that repeats about 2 times every minute when the defroster is
on and the fan is running but no other time.
That is the sound of the A/C compressor kicking on and off. The compressor runs when you have
the defroster going, as well as when the air is on. This is a normal condition and nothing to worry
about. If the noise seems odd, or unusually loud, you could have a compressor that is going bad or
about to lock up. Check the belt too, on your vehicle there is a separate drive belt that turns the
compressor. Probably normal, but get it checked out if it seems like something is wrong.
