Hello Rehayes83569, Just off-hand, since you contend that your sound system has a profound effect... I would skip past the BATTERY... (+ voltage regulator) and move quickly to your GROUNDING system...to VERIFY good clean connections throughout... More importantly... if you have any recent MECHANICAL or BODY-WORK... Very IMPORTANT ground straps are accidentally left disconnected... Typically your PRIMARY GROUND is to the engine block and BODY grounds (your trouble area) are strapped to various body elements from there... A detailed DIAGRAM on Technical Service Bulletins (TSBs) are available FREE on BBB Industries WEB at BBB Industries Premium Alternators Starters Power Steering Products Registration is required (as these are real documents. Jumper CABLE: A simple test from major BODY BOLTS in your dash area to your GROUND post directly on the VEHICLE BATTERY ought to prove/disprove my theory. Hope this helps. Carnac the Magnificent

First I think you need to take your car to a different shop and get a second opinion. It's hard for me to see a cam failure unless you abuse your vehicle.

The security system receives it's voltage through the BCM (Body Control Module) To check the security system schematic complete the main page of the link below by selecting: (Wiring Diagrams) Enter your vehicles (Year): 2001 (Make): GMC (Model:) Sierra 1500 (System:) Body And Accessories (Sub System:) Security/Anti-Theft 1 diagram found. http://bbbind.com/free_tsb.html The first step is to always perform OBDII Diagnotics to see if any fault codes are logged.

No controller should energize the trailer brakes without a signal from the brake pedal switch. Something is not right.

If the light was on and then went off, the code will still be stored in the computer. Getting the codes read is always the first step to avoid guessing. Also, driving with a flashing check engine light is a great way to damage the catalytic converter...very expensive part.

It may be the transmission input shaft bushing or bearing, located in the rear of the engine crankshaft, in front of the clutch assembly. If the bushing or bearing is dry (needs to be greased), the input shaft will still try to turn with the engine rpm, even though the clutch pedal is depressed. Also, the clutch disc may not be fully releasing, which could possibly be corrected by adjusting the clutch pedal linkage. good luck

4wd actuators are in the transfer case not the diff housing on a diff housing it is more likely to be a diff lock to lock the 2 front wheels together

Hey Anon, Take it back to the mechanic that performed the engine swap... he should fix it!!

Sounds like it is more likely the high pressure switch on the accumulator acting up (a common issue with older vehicles). To verify this, try putting 12v on the clutch with a jumper (but only for a few seconds each time) to see if it engages. If it is the pressure switch, you may have to replace it and the schrader valves as well. If the problem is an electrical connection in the clutch, yes, it can be replaced without removing the compressor but that must be done very carefully.

could be a bleed of for later models or a manufacturer modification so that the same part can be used in different in different vehicle applications vehicle manufacturers do not make may of the parts in use but use products made by specialist shops and you new unit could fit a range of applications some of which may require that hose connection

try the stabelising arms rubber could be warn and this can sometimes cause sufficient movement on the gearbox ,gear shift to kick out

With fuel injection if the pressure goes to low the fuel pump will stop and the lifters will get noisy.If you are seeing 10 lbs hot at idle I wouldn't worry to much. If you have a high mileage vehicle and live in a warm climate,go for 20w50 oil at your next oil change,some use straight 40w oil to help oil pressure on worn engines.
