I have read that the baffle needs replaced and is a common problem in the vortex engines. How much does it cost to repair or is it time to trade?

The starter stays engaged n the only way to get it to stop is take the battery cable off.put 2 new starters on works good for about a month then happens again.

2007 GMC Sierra 1500 4wd 4.8l

I am taking a long trip. My mechanic says the next thing which will probably fail is my water pump. It is a 4.8L V8 in a quad cab pickup. I am not showing any leaking at 145,000 with original pump. Would it be prudent to get a water pump replacement before my trip?

And it reduces my engine power and I turn off truck for a little while and start it its all goes off but a little while after driving it comes back on and does the same. What could be causing it?

on my 2007 gmc sierra i have a problem with the driver side rear lights my brake light works fine my directionals work fine but my daytime running lights do not work my question is is there a seperate fuse for drivers side rear and passenger side rear i cant figure out why the lights work fine for brake and directional but not running lights.btw the running lights dont work at night either but everything else does.

When I turn the cruise on the light comes on on the steering wheel control but I am unable to set the cruise control. It will not kick in. What is involved to fix and a possible cost for the repair.

Was driving and truck coasted to a stop, check the codes and only get "lost communication with abs control module"

I have replaced the lifters on one side and now having to replace the other side. I was quoted a price which I feel is outrageous. I just want to know what the average cost is to replace all lifters

In the last 5 months we've had to replace.. Transmission, MAF, Crank Shaft Sensor, and the alternator. Now it is running rough, and the rpm's are irratical. Sometimes it will stall with no warning, sluggish most of the time, and sounds like a lifter is going out. Took it to a shop and was told the diagnostics machine couldn't read the computer... HELP...

There is 14 volts to the vent solenoid plug with engine running, but when plugged in doesn't work. When I apply battery voltage to solenoid it works fine. Act like power supply from ECM has problem
