Ok so I was driving and all of the sudden my radio goes out, and so did the speedometer and all the lights on my dash...got home checked out fuses found the radio 15 fuse is blown out tried replacing it and it kept blowing out sparks...why? can it be fixed quick? does anyone know what can cause it to keep sparking?
Yes I think there is a problem in radio or in cigarette plug check if the fuse are the same for both
SOURCE: shuts off while driving. no fuel pressure. pcm fuse blows/ fuel pump relay inserted.
Sounds like the fuel pump is shorted.

just fixed this problem, change your fuel pump module, fuel sending unit shorts out on fuel level swing arm blue wire... unfortinately you must replace it as unit because of the design, fuel pump and tank guage fuel level sending unit are a one peice item, fuel tank has to come out to change unit, about a $ 700.00 repair too... fuel pump module runs about 350 to 700 $ depending on aftermarket or factory, try to find one with a lifetime warranty even if it is $ 50.00 more worth it..labor is about $ 250 to $ 400 depending on shop labor rate... definate problem though I ahve no doubt, common problem on GM... please rate my help, thanks...

On the full size, the front actuator is electric, not vacuum.
When in 4wd mode, a switch on top of the transfer case conducts 12
volts out to the actuator. Wire #50 (brown) is the 12v feed, and it
conducts to the light blue wire (#900) to the actuator.
When shifted out of 4wd, the switch opens up and no voltage goes to the actuator.
Check voltage at the connector for the front actuator (at the
front differential - it looks like a large bullet that threads into the
front diff.) If it has 12 volts, the actuator is the problem. If it
does not have 12 volts, check the transfer case switch and the power
feed to the transfer case.
I'll assume it is the actuator, if the plug to the actuator is getting 12 volts when in 4wd.
The way this actuator works, is it is a sealed chamber that gets heated
by voltage. When it heats, the pin in the end swells and pushes a shift
fork in the front differential. The shift fork engages a spline on the
passenger side of the differential, and boom! you have 4WD.
GM offered an upgrade to this actuator that is a motor instead of a
heated device. However, it requires a small harness addition, a spacer,
and a new actuator. It is about a $150 to $200 option.
If I were you, I would buy a new heated actuator. They are available at
most auto parts stores, and are about $90. They are also on eBay for
about $55 plus shipping. These are very easy to change - just thread out the old one, and thread in a new one.
Good luck. The actuator is usually the problem 90% of time but recheck all of the wire harness just to maker sure there is no short before replacing any parts.

You need to replace cluster, 99-02 Silverado GMC all will work even if it has a trans temp truck is pre wired for it. I put a 02 Denali cluster in my 01 silverado no problems. GM can reprogram hours and odometer if you want.

Make sure Parking brakes are fully released and then check the diode under the dash, drivers side above right foot, remove diode and shunt tyhe connection if lights lite diode is bad. These diode reduce the power by 25% and are prone to fail
