    When i start my truck up, it does this really fast clicking noise,,, by the firewall somewhere, sounds like something electrical, i dont think its the wires, it clicks like 5 times per second. Its an all the time deal, it sounds similar to a taser sound. Is this normal? Its an 85 full size CCC model.

    Anyone? :laugh:

    If it doesn't vary with engine RPM, and you're sure it's electrical, It sounds like it could be a malfunctioning relay, or a circuit breaker with a short.

    Mystery Ticking Sound

    Check for an EXHAUST LEAK. This is a common sympton of an exhaust system leaking near the engine.

    my injectors tick on my tbi. but 85 wouldnt have that so :confused: , try spraying a mist of water at all your electrical and see if something sparks (do it in the dark of course) i had to do that with my furd, worked pretty good.

    Check the disty cap, I had taken the tranny out and had the motor resting against the cap. It ended up shifting the cap and the rotor was hitting the cap making a ticking sound.

    I would suspect a exhaust leak. Re-tighten your manifold or header bolts.

    Did you check the spark plug wires? See if any have become burnt or cracked due to exhaust heat. If you dont see any physical sign then start the motor. Spray water on the plug wires and see if it help with finding your tick.

    That's what I was going to suggest as well... a bad wire could be the problem. One could be burnt through, or worn through and arching onto something... makes a nice little ticking/popping sound.

    I have that same problem, but I don't hear it in the engine bay, just the "cab".

    An exhaust leak would vary frequency with engine speed, as would the rotor, injectors, spark plug wires, etc.

    Do all electrical components function right? HV(AC), horn, headlights, blinkers, cab lights, wipers, etc? Is it inside the cab or in the engine bay? Could you use the old rubber hose stethascope trick to pinpoint it's location closer?

    I had a ticking relay whenever I'd honk my horn in my old '79 and it turns out it was my horn control relay way up above the steering column was dirty. Pulled it out, cleaned the contacts and it worked up until the day I sold it.

    In your case, if it is in fact a relay, you should be able to pinpoint it by touching it and feeling it clicking while it's doing it. When you find it, shut 'er down and pull that relay then start it back up and see what happens. If the ticking stops take the dead one into any auto parts store or radio shack and put it on the counter and say give me a new one of these :)

    Good luck

    -Mike
