Hi, My name is Greg and I own a 1996 Chevy K3500 Pick-up. Can anyone tell me approximately how much boost my turbo should put out when it is new. I am getting a maximum of 8 lbs at 14 years and thinking I might need to replace it.

I am tring to wire a 4 wire trailer plug. the brake lights and turn signals are separate wires on my 2005 Chevy silverado. I don’t know how to wire brake lights and signals to trailer plug. it is like I can have 1 or the other but not both.

My car shakes a lot when stopped.  What is wrong.

2000 Chevy S10 Extreme is cutting out when being driven long distance. My fiance drives the truck an hour to work every day. Once he gets almost there there is a hill to climb and every time he gets to the hill it starts cutting out and will then continue to have this problem the rest of the drive there. Well he also says he can pull over shut it off and start it again within a few minutes no more than 5 and get several more miles down the road before it will do it again. I had the truck all week last week in town to see if it would do it while I drove it around town and it never did. He drove it today and once again got to that same hill and there it was again. We changed the fuel filter already and that didn’t help. Any ideas what might be wrong?

i have a 1995 chevy 1500 p.k. and my fuel pump will not go off unless i disconnect the battery. i replaced the relay also unplug the computer and ingtionion switch to make sure they where not the problem. even with this all un hook if i connect the battery the fuel pump is up and running. i also figure out that if i take the relay out of the fuse panel and use a jump wire i can make it turn on or off. as soon as i start the vehicle it goes back to running all the time until i unhook the battery or jump across the fuse box

Y is my battery dying even when my car is turned off . i have replaced the battery and the car just drained that one to … when i hooked the new battery up it was sending large sparks and everything in the car was turned off ….. i can jump the car and it will start and i can drive but the minute i take my foot off the gas it just dies…..

I have put a 4.25 stroke forged rotating assembly into a 30 over 454. When I received the block from the machine shop, they had painted the lifter valley with a grey graphite paint. ( they said this would aid in oil return). When I assembled the engine, I had trouble putting several of the lifters in the bores. Assuming the paint would quickly wear off shortly after initial fire up, I took no steps in cleaning the paint from t he bores. Unfortunately the engine is now complete and I have what appears to be a top end tick after 1500 RPM. In your experience, should I allow the engine to wear itself in or am I looking at a top end tear down to remove the paint from the bores?

I have a 1996 K2500 4×4 5.7 liter that suddenly stopped running while I was driving.  It had to be towed and now I am stumped as to what the problem is.  The filter is fine, all fuses have been checked, if I pour gas into the carburator it fires up it is just not getting gas to the carburator.  The pump is okay.  Anybody have any suggestions as to what I can do to try and get this truck running?  Please post and thankyou.
