SOURCE: 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

This could be a number of things but i think that your problem sounds like a vacuum leak or an EGR problem. Try listening for leaks and try un-plugging the EGR solenoid valve one time.

Hi, that's possible but first check the ECM fuse and use a test light to check for power to the injectors on the red and white wires. The computer uses a number of sensor inputs to calculate the injector signals required. If these signals are not available, the computer cannot send the appropriate injection metering signal and will usually set the engine light. Is the engine light on?

Hesitation , skipping,engine cuts out when accelerating


Im having the same issue I believe. I have a 94\' Chevy 1500 and when i accelerate it will jerk like the gas has cut out but it wont stall. It just jerks and slows me down. It only seems to do it when going up a hill. I feel like it could be the fuel pump or possibly some intake gaskets?
