For a engine to run or start it needs compression, spark, fuel and air. I tend to think in this case the fuel may be leaking back into the tank due to a leaking check valve in the fuel pump or line. If you do not find the pump is at fault read further...

Before you do get carried away it is very important to start with the basic and simple checks; Get a can of carb cleaner and when the engine is running spray in areas where there are any vacuum hoses or possible intake leaks. Check and replace spark plugs if needed as well the ignition wires. Check oil level just in case since the pump will not run if oil pressure is too low in many autos made these days

There is the timing of spark and the correct mix of air to fuel. If this is a new vehicle then this gets a bit involved, if you had it all summer and it started great in warm weather we can narrow it down to the cold start circuit which may involve the fuel pressure. Some autos use two fuel pumps; one in the tank and one inline to provide the correct amount of fuel I did not check in this case but if it does use 2 pumps then I would be looking at the in-tank fuel pump.

This engine is computer controlled so I would also be looking at the temp sensors to be sure that they are within range. Most tests can be run with a cheap multimeter.

Back in the day truck drivers swore that using some ATF in the fuel would clean injectors but I already know that most cleaners are just not going to do it. At the shop we would remove the injector and run them with a special set up and a concentrated cleaner. Often we would find that the injectors that need to be cleaned also leak and so do not spray well no matter how much they were "cleaned". But you have little to loose by trying a cleaner. Seafoam is a popular item that you may buy to clean the fuel system.

Lastly we saw a lot of strange problems caused by poor grounds in the electrical system. A ground strap that is poorly connected can cause any number of issues. Unfortunately there is no one great answer to this problem and some troubleshooting may be required.

Try running some concentrated fuel injector cleaner on next 2 tanks of fuel, before you get to pulled fuel pump. Spark plugs need to be changed every 60-80k miles for city driving or 80k highway driving on regular fuel. Fuel pump filter can also restrict fuel, that would be the next thing to check/replace (every 200k on reg fuel).

On a 2004 chevy tahoe. Once the instrument cluster wire clip is detached and new bulbs are soldered on the cluster. Does the instrument cluster have to be reprogrammed ?


Shouldn't need reprogramming. I removed the cluster from my 04 Silverado and sent it in for repair and replacement of the bulbs. It was out of my truck for 2 weeks. When I got it back everything worked just fine, no problems at all.

I have a 1995 Ford Explorer Limited and the high beams work but the low beams and fog lights do not, please help....


These trucks are known for bad multifuction switches.
the switch that i talk of is the signal switch , the handle is the switch, it bolts to side of steering column . this switch controls the signals and the headlights and high /low beams. the other thing is the headlight switch connector, the connector some times goes bad and starts to melt or just comes out of the connector. you will need to remove the cover to steering column, the screws are located under the bottom cover in holes. remove cover and check connector and then test for power if you have power going into switch but not coming out then switch is bad.

the last thing is to make sure the bulbs are good , make sure the headlight bulbs are good , and also the driving light bulbs, test for power at the connectors to those lights to.
You will need to do a little testing to find the problem.
