I pulled the wires off the spark plugs and found out the #1 cylinder was not firing, the others were. I switch the 1 and 2 injectors, but it made no difference. I went ahead and sent the injectors off to have them all cleaned and serviced. I put them back in and still the #1 was not firing. I have spark at that cylinder, have swapped plugs and wires, but still the #1 won't fire. I wonder if the timing could be a little off to cause that?

Hi Riverside,
I think before you pull anything more apart. Since you know #1 is not firing, why not change the rotor and cap. If you did change wires, and #1 is still not firing, it could be a cracked or dirty cap. Cheap and easy work, and considered part of a good tune-up. You could also get a volt meter and see if #1 injector is getting juice while cranking. You can do it with a multi meter, You would have to look up the voltage parameters for fuel injectors. Although I have heard of something that goes between the injector, and plug in that works better. One thing for sure...you're not a quiter.
Good luck Riverside

A new rotor and cap did not fix it, but I was glad I changed them because they were worn. A friend told me to take a water bottle and squirt around the intake manifold near the #1. A sucking sound from the water showed a vacuum leak near that cylinder. I had earlier put on a new intake manifold gasket, trying to fix things, and had screwed it up. There were slots for the bolts, with one bolt hole at the rear near the #6. There was a hole for a dowel at the front near the #1. I hadn't used the dowel, and had the manifold too high in the front, creating a slight gap at the #1. I put a new gasket on lining it up using the dowel, and the truck runs so good you would not believe it. The whole thing started out with plugged injectors. It's fixed now. Thanks to everyone that helped me out through this ordeal.
