2000 blazer hesitation and poor Acelleration
i have a 2000 blazer i bought a month ago. now is having a hestation under heavy acceleration. took it to one shop. told me the trans was slipping into 2nd.
proceeded to another shop and they told me the trans was fine and it was the engines performance causing a hesitation and making it sloppy.
bought it and was told it had new
crank sensor
cap and rotor
plugs
wires
fuel filter
trans fluid
trans filter
shift sensor
CEL is on from cat being deleted.
also has a code for the crank sensor. cleared the code at oreillys and still comes back.
2nd trans shop said i should take it in to someone who does engine work.
ive read some people have problems with the MAF sensor causing this.
bad fuel
crank sensor
or the plugs wires etc.
checked fuel pressure and it was in the normal range. 55-60 with key on.
sometimes it wont start. and i have unplugged crank sensor and plugged it back in and it usually fires right up.
any help. dont want to keep throwing money into it on sensors that wont help!
thanks!

when you replaced the crank sensor, did you disconnect the battery and put it on AFTER you put the crank sensor on? if im not mistaken, it will not relearn and cause problems. i was also told it had to be relearned using a GM tech 2 which isnt cheap and usually on GM has them

I did not do the crank sensor. It was done previous to me purchasing it.
It's currently in the shop. Got the rear diff pinion bearings replaced.
It wouldn't start. So I had to have it towed to another shop to get worked on and figure out the no start now. Hopefully he can figure out what's wrong. It's outta my hands now :/
