Relay diagrams, and pin locations

1998 5.7 Chevy 1500 C truck. It will run for two seconds without pouring fuel in throttle body, then stops. Changed fuel pump relay. Fuel tank, fuel pump, fuel filter, cap and rotor. I will change wires and plugs next. It does run when I pour fuel into the throttle body. Im getting these codes po452 p1626 po463 po108 not sure what they mean. Should I clear these codes?
I have good fuel pressure 60 psi at the test port. This is not a daily driver. Truck has been sitting several years!

Well it all started one day when i went to the store for lunch turned off my truck went in then came back out, went to start my truck the dash came on as normal, then when i went to start it i turned the key and lost all power everything was gone i coulndt even us my remote to lock/unlock.

Sorry in advance for the length of this. This truck has set for a couple of years the mice have found it home. I've not yet found chewed wires anywhere but there has to be some. I put a used battery but a good one in it and tried to start it nothing happened at all. I started looking into the fuses. I found several missing one of my boys must have needed some I guess. I don't know if I have found all that is missing and I'm not sure how to find out if ive got them all replaced. So I finally get some dash lights to come on battery light, brake light, and of course the lock down is also on. T… Read complete

My Silverado was broken into an they cut my stereo harness an took something from my fuse box on the side of the dash. A relay or plug of some sorts now my truck won't start turn over or none of my gauges work? Any advise would be so great to have my truck back

The electric coolant fan relays , underneath , buss bars are totally corroded and need to be replaced ! Saw a relay upgrade for my year &model truck , an upgrade for the relays on E'bay. Will they work ?Is there a wiring diagram for it ?

Horn fuse is intact. Can't find the horn relay labeled anywhere in the manual or fuse boxes. Car was broken into yesterday, but it worked afterwards. Horn failed to work today. Which slot in the fuse box is the horn relay in?

Left the window down during a rain storm driver side now I have no power from door, panel and truck will not crank or start. When turn the switch, the gauges work, but turn the key. Nothing happens. Can fill the relay, clicking starter has power. Fuel pump comes on.

Some one removed my starter relay along with other relays. Starter won't turnover

I put a new battery in this truck about a week ago. Then a few days ago I ended up getting ahold of some bad fuel which had me stalled out in front of my house barely making it back from the store. So long story short... when getting fresh gas In the tank I figured I outta go ahead and change the plugs since I had them anyway plus the bad fuel issue figured it wouldn't be a bad idea. Then that lead to 5 out 8 broken spark plug wires which took another 2 days to be delivered. So now I get these replaced everything sound as it should be and now I turn the key, I have plenty of power from the bat… Read complete

It had 51,000 Mi two and a half years ago when I bought it. It has 95,000 on it now. New battery 14 months ago. It has plenty of juice. So I think it's either the starter, or maybe a starter relay.

When I turn the truck key on the tail lights come on but the head lamp switch is in the off position. When I hit the brake the tail lights go out and the third brake light comes on.

My driver's side mirror works fine using the controls on the door, but when I select the passenger side, I can't operate the mirror using the buttons. I looked up the fuse box diagram on this site but it doesn't show a fuse or relay for the passenger mirror.

I have windshield wipers not working and no power to the windshield wiper motor I changed windshield wiper switch and checked fuse cannot find relay

My low beams all of a sudden stopped working first it was the passenger side which the wire is completely dead then it was the driver side. I had to jump a wire from my low beam driver side to my low beam passenger side because it changing the headlights. I lost complete power to the low beam on the the passenger side i.e. me jumping wire. Now my issue is my driver side one out. I tested the wine at the jump point and there is very low voltage when I touch my Test light to it. I believe I changed a headlight relay not sure if it was for high beam low beam and I've checked the fuses and I can't… Read complete
