Question about 1999 GMC Sonoma
I was driving then suddenly it turned off while driving.starter is okay and working,i changed fuel pump,spark lugs,the computer box,fues boxs and still not working,we tried everything but nothing! if i put some gaz in the engine it turnes on for a sec which we think its fuel pump but we test fuel pump which is still working,there is something between engine and fuel pump that wont let the truck starts,we test the wires that jump the fuel pump but they all good.can anyone please help??
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
