Engine Performance problem
2000 GMC Jimmy 6 cyl Four Wheel Drive Automatic
----------------------------------------------------------------
I have a 2000 GMC JIMMY about 3 months ago as i was driving to work in the morning i stopped on a red light when the light turned green i notice that my truck had turned off. I tried to turn it on but it only made the noise when its gonna start but it didnt. I ended up getting it towed to my house. i have checked for it to have spark and it has good spark i aslo checked for the fuel pump pressure and it has 55-60 psi. i also checked for it to have any codes but nothing came up. I put a new battery, and a new starter. Even if i prime it it wont start so is been 3 months and i havent been able to get my truck started not even one time.

Have you done a relearn on the pass-key?
GM PASS LOCK RELEARN- Ignition to "run" position, try to start and let key return to "run" position
Approx ten minutes security light will go off
Turn key "off" and wait 5 seconds
Repeat 2 more times for a total of 3 relearns.
Turn key off, then start it

my 2000 jimmy did that last week it wouldn't start and I had it towed to the shop and they had to replace the fuel pump.

That good, but his pressure is pretty good...
