1997 Chevrolet Silverado Z71 p0758 Won't shift


P0758 code is shift solenoid B electrical /2-3 shift solenoid circuit electrical, It better to inspect the wire going into the transmission they have a tendency to leak transmission fluid into the circuit make inspection for proper connection if you decide to replace the solenoid you still need to inspect the circuit for proper mating. If this solenoid fails and you wait to long to replace it you can loose the ECM due to the high power draw it takes from the ECM.

My 1990 riviera will run great, as you are going down the road it will shut off,but crank right backup. whats wrong?


Check the ECM part number. If it is a 1228253 that is your problem. get a 16198264 the other number does just what your car is doing. I worked at a Buick dealer and know about the problematic 1228253 ecm.

I have an 89 chevy c1500, 5.7, 2wd. Had it running and trying to get it timed. During this process i noticed the injectors quit giving gas. I put gas in it and nothing changed so i have been chasing the...


the reason the injectors stopped is because the motor is not running.this is a safety precaution built into the computer so the engine won`t flood.if the fuel pump is not working then you will have to check powers and grounds at the fuel pump connector by the gas tank to see if the unit is getting fed power and ground.someone will have to try to start the car while you check this out as there is a 2 second prime circuit if the car is not turning over.also this system uses the distributor to know that the engine is turning over to start.you may have a bad pickup coil in the distributor.this system also grounds the injectors through the ecm so you should have power to the injectors when the ignition is turned on,for your information.

2005 chevy silverado won;t start.


i had the same problem, and it turned out the coil pack was moulding inside wich stopped the spark all together, i ended up changing my coil pack and putting on new wires because the ends connected to the coil were very corroded and that cures the not running part just fine


enjoy
