Welcome, I'm Chris (aka Moose), my normal schedule online is around lunch and after dinner past midnight.

Will it at least crank?

Are there codes stored?

Did you remove the engine to get the transaxle out?

Customer: replied 1 month ago.
it will crank i dropped the k frame to remove the clutch an replace it put the whole car back together the car started up an ran for about 30 seconds before the pwr reduction message pooped up the engine started running ruff an it stalled an will not restart i have been threw everything again an everything is hooked up an is tight is it possible that it needs to relearn the keys
Expert:  Chris (aka-Moose) replied 1 month ago.

Any way you can get it scanned to see which codes are stored?

This warning normally comes on when the computer detects something wrong that could result in engine damage like a failure of the throttle body, coolant temp reading or oil pressure reading.

This is my 1st answer of what can be many. You the website and myself expect you to have a ~~~5 STAR EXCELLENT~~~ experience with my help. At the top of your screen is the rating box that you only get to use once. Please make sure to complete the mandatory rating when ready or reply and say "I am pleased with my answer". Not rating or rating 1-2 stars does not benefit you nor me in any way.

Thanks Moose.

Customer: replied 1 month ago.
i dont have a fancy scanner the only thing that comes up is evap emissions codes
Expert:  Chris (aka-Moose) replied 1 month ago.

Are you able to check the fuel pressure, ignition spark, and injector pulse to see which is missing?

Customer: replied 1 month ago.
i have fuel pressure im not getting any spark its not firing the coils
Expert:  Chris (aka-Moose) replied 1 month ago.

No spark can be caused by no crank sensor signal getting to the PCM. Have you checked that sensor?

Customer: replied 1 month ago.
no i have not but that sensor was not messed with
Expert:  Chris (aka-Moose) replied 1 month ago.

Let me know the results of checking out the CKP sensor.

You may find the only way to figure this out is going to require a better scan tool.

Customer: replied 1 month ago.
what is the ckp relearn procedure on this engine an what is required to do it
Expert:  Chris (aka-Moose) replied 1 month ago.

What liter engine do you have?

Customer: replied 1 month ago.
2.2 would that be the cause of problem due to having pulled the engine out
Expert:  Chris (aka-Moose) replied 1 month ago.

A scan tool is needed to perform the CKP variation relearn procedure.

Customer: replied 1 month ago.
any idea witch scan tool i would need
Expert:  Chris (aka-Moose) replied 1 month ago.

The GM tech 2 scan tool is the preferred tool.

Customer: replied 1 month ago.
are there any other scanners that do more then just the gm's at that price im better off to take the car to the dealer
Expert:  Chris (aka-Moose) replied 1 month ago.

You can purchase a snap on tool that can be used on all makes and do most all features that a dealer scan tool can perform.

Customer: replied 1 month ago.
could this be the cause of the car not starting
Expert:  Chris (aka-Moose) replied 1 month ago.

Yes this can be one of the causes for a crank no start concern.

Customer: replied 1 month ago.
replaced ckp an no change same problem
Expert:  Chris (aka-Moose) replied 1 month ago.

Replacing parts without being able to diagnose they are in fact to blame is going to cost you alot of money and time. Do you know anyone with a better scan tool?

Customer: replied 1 month ago.
$34 part not a big deal no i do not not without taking the car to the dealer or spending the money on the tech 2 myself any other ideas
Expert:  Chris (aka-Moose) replied 1 month ago.

Key on, one coil unplugged.

At #1 is the black wire ground, brown wire ground, pink/black wire power?
