Question: truck won't start.

Hello, my name is James. I have a 1997 ford F-150 with 4.2 liter engine. I have just replaced the head gaskets to the tee.
But I confused the number four cylinder for number . When placing it at top dead center. I have hook every thing back up. And ran the coil pack and spark plug wires the way the diagram shows. If the number four cylinder was at TDC would that have messed up the timing?

Yes you have messes up the timing. You need to set it up on #1. When you did the head gasket did you remove the timing chain. If so you have to reset the timing chain then the distributor. If you did not remove the timing chain. You just have to reset the distributor. Remove the #1 spark plug. Remove the wires going to the coil so it will not spark. Then have some one crank the engine by tapping the key. You put your finger nest to the spark plug hole. But do not put it over the hole just next to it. when you feel air getting pushed out of the spark plug hole stop cranking the engine. Look at the timing marks. Then crank the engine by hand to match up the timing marks. Now you can put in the distributor. Put the plug wires back in the right location. Then try to start the car.

Car Brakes: How Do You Know When to Change Them?

By Zach Bowman For those who suffer a daily commute through heavy traffic, your vehicle's braking system can bring thousands of pounds of metal, plastic and empty Starbucks cups to a stop hundreds of times before you get to work. It goes without saying that these pieces wear out, but they do so slowly, meaning you may not notice they need attention until ...
