2003 Chevrolet Silverado 2500 - Page 3 - Answered Questions & Fixed issues

Do you have normal fuel pressure and spark ?

Does the static change with engine speed? If so there are filters you can put in the power wire to the radio

check the firing order and timing after a distributor replacement

on the line, lube the seals and make sure nothing is inside hole.

had a 1999 suburban do the same thing the new pump came complete with sending unit and a new end plug the connecters are bad about getting moister in them at the top of pump and corroding did you change the plug part stores should sell these if you did not get one i found this out after changing my pump 3 times same thing also found cheap pumps the wiring going through the pump plastic at plug is very small and gets hot and melts when it cools it shrinks back and makes connection runs for a while then stops

check the oil level.

there is no reset switch on any GM products. have fuel pressure check

Only Ford products have a switch for the fuel pump.If your pump is not working, the pump relay would be the first thing to test.

could be the bearings have u tried some wd40

You may have a bad fuse or a bad relay or master control switch on the drivers door or broken wires at the drivers door where the wiring goes from the door between the door hinges into the body or bad lock motors.

check the slave cylinder

Max Pressure is on the sidewall of all tiresI usually go about 2 to 4 lbs less on all vehiclesIt should be on the label inside the drivers door,but I would never go by that & everyone willtell you toIf you want to run 1960's air pressure go aheadIt's about the tire, not the manufactures recommendationIf you run less than near max, you will wear them outvery soon

On a 1988 model which should be the same as 87, I show two injectors in the throttle body. Inj 1 has red and blue wires and inj 2 has green and white wires.The red and white wires should be battery voltage, and the other two are ground signal wires from the computer.

It is most likely the water pump, the air flow under the engine causes the coolant to go back under the truck. Fell under the front of the water pump for moisture or a slimy liquid.

If the passkey system were not working the engine should not crank and the fuel injectors would be dead. The security light would also stay on.The fuel pump relay gets battery voltage and also voltage from the key switch. The computer grounds the relay to power the pump.The crank sensor does not come into play until the engine is cranking and it supplies a signal for the ignition and injector pulse.Are you not getting power from the key switch to the relay, or from the battery side to the relay ?

it could be the hubs are not all the way engaged or disengaged but most likely it's your universal joint between hub and axle

firewall on the passenger side under the hood.

check you fuse and relays

check ****** fluid... your clutch or tanny might be going out also

I will give you a general answer. Some cars have an Ignition relay in the powerbox and when you turn on the Ignition key, it activates the relay.Now you can go to Autozone.com and register your vehicle for free and then print out images of your fusebox and chassis diagram.The horn relay is the same on many Ford and GM products. You can switch the relays or test one relay with the horn button. If you can not get the horn to work after you put in the former Ignition relay, then the relay was bad. You can also use the former horn relay to start your vehicle.When you ask for info, you do need to let us know what you are driving.
