My 89 f150 quit i have changed fuel filter the coil but it still seem not to have any spark can u help me i have been around cars and trucks my whole life even work in a shop for many years but this has me thinking.

Test the continuity in the coil. Also test the connection end to see if it is getting power to the coil. I have also received bad coil packs from auto parts store , so if its under warranty change it just to make sure . Also, take the tape off the wiring going to the coil pack and check for breaks inthe wiring. Timing issues or crankshafts or crankshaft sensors can cause this. The sensor itself runs $20.00 and up. Hope this helps. Spark plug wires can have breaks in them also.
