This is a 1994 chevy silverado 5.7L V-8. The problem is that the truck will start some times and other times it will not start. Some times it just quits working when you come to a stop or it will keep running util you press the gas. But keep in mind that some times it runs perfect. When it wont start you have to pump the accelerator really hard, this is a TBI (thrittle body injection) you should not need to pump a TBI, when you turn over the engin and it will turn over but not start it has spark. When you finaly get it started black smoke comes out of the exhaust will fuel in it. It runs really crapy too. We have replaced the fuel filter, fuel pump, fuel strainer, ignition coil, ignition control module, distributer cap, rotor, codes. Some times if you can get it started it will get the check engin light but will eventualy even out and run perfect and the light will cut off and give no codes. The car shop gave up on it so this is my last hope. They have replaced sencors and tried two diff tbis. I think that it is the ecm. What do you think?
have the same problem?
