If you have replaced the switch, and it is still doing it it sounds like you definately have a short somewhere in your wiring. On the other hand if the dimmer is in the turn signal arm ( forward bright back dim ) the problem could also be there in the dimmer switch, such as a short being caused by that dimmer switch being faulty.Auto Zone and Discount Auto Parts both test a lot of your electrical problems for free, and/or may have some knowledge to more accurately pin point the problem. Not sure about Pep Boys or some of the other discount auto part chains.

by looking at the manual for my 97 Camaro and if you say that the switch is good then that helps narrow it down a lot, because i found a circuit breaker... not a fuse!...located inside the headlamp switch itself. good luck and let me know if you find it... c.b's. are usually resetable please let me know if you fix it because i have the same car and it might go out on me someday..thanks man! also you can see if your getting voltage on the yellow wire when the switch is in the "head" position..if its not there, then its almost a guaranty that its the c.b.

Be sure that the fuse to the fuel pump is good, and the wiring to the connector at the fuel pump is not damaged and the ground wire is grounded well.
The fuel pump circuit on some applications is controlled by the OPSU (Oil Pressure Sending Unit) and it will shut down the fuel pump if there is not enough engine oil pressure to safely run the engine, and you can tell if the OPSU is controlling the fuel pump circuit in your vehicle because there will be more than just one wire going to the OPSU, and this type of system can prevent the fuel pump from running if the OPSU is faulty.
On all applications the ignition module located inside of the distributor is what generates the signal that is used by the ECM (Engine Control Module) to run the fuel pump, time and fire the fuel injectors, as well as the dwell signal to fire the ignition coil.
That does sound like a malfunction with the ignition module inside of the distributor, and you can remove the ignition module and have it tested for free at most auto part stores.
If you do purchase a new ignition module be sure that it does come with a silicone grease or a die-electric compound because it is a heat sink and the ignition module will burn up without it.
To install the new ignition module first clean out the mounting surface inside of the distributor. Then completely coat the metal contact surface under the ignition module with a thick coat the silicone grease or die-electric compound and do not leave any of the metal contact surface of the ignition module un-coated with the silicone grease or die-electric compound, and be very careful not to over-tighten the ignition module or it will be damaged.

If you have daytime running lights but when you turn on your regular headlight on they do not come on. Take the bottom of your steering column off (Two Small Screws) and look at the back of your turn/dimmer switch make sure that the light blue wire is connected. The wires will break off after years of raising and lowering your steering column. My 1998 K1500 did the same thing and this is what happened to mine

You need to check the bulbs.These are known to go out a lot.Also you can check that you have power to the lights with a test light.Sounds like a bulb or wiring problem.I have had a few of these that are broken off because they are so close to the ground.Depending on if your four wheeling or in snow country.Hope this helps.Good luck.
