Driver rear exhaust manifold

Well, the fluid sounds like it is going somewhere. Look on the ground.
Could be a line that blew, or a hydraulic brake component that is leaking.

I would leave it up to a brake service professional to repair this problem, which is beyond just adding fluid to the master cylinder.

Brake systems can be complicated to repair properly when the pedal gets to the point of going to the floor and the brake light going on which is always a bad sign of impending bills to repair either with parts or with brake expertise.

If you have more specific questions on the braking system I would be happy to answer.

first thing check all fuses, if ok your problem more likely rear tail lens circuit board where your bulbs push into. the sockets over heat and melt . this is a problem with these trucks from 1988 to 1999

Check for ground in the harness or add one directly to the radio

Damage wires,did you check gap,did switch wires?

Best way to fix it when you run out of gas is this. Because you ran out of gas, means your fuel filter is out. When you run out of gas, you end of getting like a air blockage in the line. Now, professional way is to take fuel filter off and fill with gas and put back on, BUT i will tell you a back yard mechanic secret way. Is get a can of starting fluid ( you can get at any auto parts store) and while someone is in side the Pickup, have them ready to turn the key. You are outside with the hood up, and you will be spraying a little bit of the starting fluid in the air intake of directly in carb area ( if carborated) but just spray into air intake. Have them crank the engine, at same time you will spray starter fluid in air intake, just a couple of quick sprays. You will notice it will start and maybe die again. That is normal, you might have to do this a couple times to get things flowing. HOWEVER, what normally happens when you run out of gas, the fuel filter picks up all that junk that has been gathered in the bottom of fuel tank and it has clogged your filter. FOR SURE, if you replace your fuel filter, it will solve this problem. Thank You, and I hoped this helped you.

you have a wiring issue there...check battery connections, connections at altenator, junction box and fuse pass through at the firewall. Make sure you follow your ground wires too should be one from the battery to block and frame to block

CK COMPRESION AND FOR SIGNAL A THE INJECTORS LIKE POWER AND GROUNG SIGNAL FROM PCM

If you haven't found the problem already. I suggest looking at the drivers side radiator tank they usually crank and seep slowly. If not leaking there, it's probably the intake gasket. Both of these problem are common to this make and model.

Make sure the injectors are metering. They are fired off of the pick up in the bottom of the distributor.

A 4L60E has 16 pan bolts and a 4L80E has 17 pan bolts

You can replace it with another 4L60E 1998 and newer and you can upgrade it to the 4L65E which is the same but uses 5 planetary gears in stead of 4 that is used in the 4L60E.
1998 was the change off year i believe where they started to section off the transmission in to three parts. The bell housing, body and tail end. The tail shaft housing uses 5 bolts to connect to the transmission and the 1997 transmission and earlier uses 4 bolts, but internal parts had no changes other then the 4L65E.
Thank you for using fixya and good luck.

P1404 = EGR valve closed pintle position.

There are 2 fuse centers. One interior and one in the engine bay. The diagrams for both should be in the owners manual. If you don't have one, you can get one at the link below. http://justgivemethedamnmanual.com/gmc/gmc-sierra-owners-manuals/
