Hi, If you look very carefully you will see the numbers on the distributor cap. Line them up with the right plug. Firing order 1,2,3,4,5,6. right side (passenger) 1,3,5 Left side (driver) 2,4,6
sometimes if a fuel pressure regulator goes bad , you will be able to smell fuel fumes under hood. a leaking pressure regulator will cause---hard starting, poor fuel economy, stalling, check engine light, gas smell under hood. also check all fuel lines under hood.
You could have mixed up the order of the spark plug cables causing the firing order to be wrong. What is the exact year, make, model, and engine size of your truck?
