Yes the fuel pump and some dirts might be in the fuel system (i.e. the tank, fuel hose, fuel filter)

Good luck.

Check the plug in for the crank sensor and the plugs on the ignition module and coil. All of these are real close to the starter. Also did you hook up any ground wires attached near the starter.

My 99 GMC sonoma wont start..


ok... there are a couple of things you can do. i must have miss typed on the cap,rotor . in the back of the motor where the plug wires conect that is the cap that is bolted to the distributor with two torques bits that i believe are t15 in size. there may lie your problem. the posts inside are made of aluminum and they get coroded and dont alow the proper spark. the other commen problem is the exhaust the catalitic converter becomes pluged up. something you can try is remove one of the oxigen sensors and try to start it up if it runs the cat needs replaced. the o2 sensor is a 7/8 nut to remove it. give it a try
