Hey guys, I've got a problem. I have an early 90's gm P/U with a 350 engine. I drove it into the shop a couple days ago to melt off to do an tune up. I changed the oil serviced the K/N filter and did the basic tune up of plus, wires rotor and cap. Now the truck won't start. I double checked the firing order and it's good. I pulled a plug and the spark is strong. The fuel pump does not seem to be pumping but looking down the top of the intake when the key is turnd there is fule sparyed into the bowl. What could be the trouble??[/align]
