This Truck only misfires on the odd cylinders 1 3 5 7.The problems is that it is getting spark and no fuel. The even cylinders all run just fine 2 4 6 8. So what is causing one side of the motor to get gas and the other side won't. Is it possible all 4 injectors are bad? Or is this truck in need of a new computer. truck has only 77,000 mi
-thanks Shooty

I would think that would be something more along the lines of the fuel rail. If it isn't to hard to take the fuel line off where it splits see how hard it is to blow thru. But it is also possible that your injectors are bad, seems kinda funny that they would all go bad on one side of the engine at one time though. You may have a line kinked after it splits to and could be a lack of fuel pressure on the driver side. I don't know if you can check the injectors or not but if you have a book and it says you can I would check them too.
