Sway bar
Did you measure from center of bolt hole to the center of the other bolt hole.?
2003 s10 blazer cranks no start . when I was trying to test the crank sensor signal wire I found 10 volts present with ignition on not cranking. the ground wire has 12.5 with the key off and 12.21 vol
Will a scan tool communicate with it or on the screen does it say NO COMM ! That's how you test a PCM/ECM . If no comm ,check power an ground's ,that's it .
Why were you messing with the crank sensor ? If the fuel pump primes for two seconds there is nothing wrong with it . When cranking the engine the PCM/ECM will only energize the fuel pump if it see's an input from the crank sensor ! You will not see 12 volts on the crank sensor signal return wire ! Crankshaft Position (CKP) Sensor
The CKP sensor is a three wire sensor based on the magneto resistive principle. A magneto resistive sensor uses two magnetic pickups between a permanent magnet. As an element such as a reluctor wheel passes the magnets the resulting change in the magnetic field is used by the sensor electronics to produce a digital output pulse. The PCM supplies a 12-volt, low reference, and signal circuit to the CKP sensor. The sensor returns a digital ON/OFF pulse 3 times per crankshaft revolution for the V6 engine, 4 times for the V8 engine. The CKP sensor reads the crankshaft mounted reluctor wheel to identify pairs of cylinders at top dead center (TDC).
Sluggish start from stop, like its starting is 2nd gear
good old-- needs a new transmission answer to a problem--
codes do not recommend a new transmission but give causes for the problem
like servo, solenoid, pressure , torque converter clutch etc, possible mechanical failure
with the transmission operating fine after 10 mph there is no mechanical problems requiring a new transmission so it is electronic issues that have to be addressed
the issues could be a simple broken vacuum hose to the transmission actuator, wiring connections ( corroded , water , loose broken wires)
Take it to an accredited professional transmission specialist shop and have a proper diagnosis and quote done
2003 blazer wiber motor not shut
Usually a problem with the logic module inside the wiper motor housing. This is an item that can be easily replaced with an after-market unit.
Where can I find the other end of this vacuum line it's on a 03 blazer v6 vortec
Hard to see, BUT One of the most popular ones that is disconnected for one reason or another runs your air out of your vents in the cab. Symptoms would be only blows out of the defrost. One of those hoses runs right over to your fender underneath the metal, very hard to see and easy to miss. Run your finger directly over to the finger under the metal, you'll feel a plastic nipple sticking out. IF you don't see one of these hoses going straight to your fender (drivers side), that's the one. From where the T is located, run straight over to the fender, hard to explain. Hope this helps!
