    ok i have put maybe a couple thousand mile on my new plugs and wires! not to much, but my problem is that when i go to start my xlt sometimes it can crank over for as long as 5 seconds before it sparks adn starts, could anyone suggest what the reason for the long start could be ?? i mean it starts and runs fine but i would like it to fire quicker!!

    On my '92, it's because the check valve in the fuel pump is bad. This allows the fuel to drain out of the fuel rail, which means it takes longer for the pump to repressurize the fuel system. A couple of things to try:
    1) Next time you start, try cycling the key from on and off before turning it to start. Each time you turn the key on, you should hear the fuel pump run. See if this makes it easier to start.
    2) Put a fuel pressure gauge on it. Run the pump (ground test lead), then see how long the fuel rail holds pressure after you shut the pump off.
