G.M. start problem

[338Shooter]

Glad you got it going. My grandparents have a 99 4x4 suburban than needs a transfer case encoder motor. It has been a good vehicle since they've had it. The 96-99 chevy trucks and SUVs are some of my favorite. They are fairly easy to work on and most of the parts aren't really expensive. I love my 97 z71 truck.

Burban's will last a lifetime if you treat them right, I will have mine for my kids, and will hopefully die with one in the garage, swear by them, have never given me serious BS. Glad you got it figured out, or that GC did it for you!

Baking is wonderful payment for auto services rendered, get to it!

YAY. Well best guess we all have is the starter had worked its way around and somehow got mis-aligned thereby causing it to lock itself up. Zombie, wrenchbender and me put a new starter on it and had to do a little ummmm....adjusting to get it lined up. Seems to work ok now. I want to give a big THANK YOU to Zombie, Wrenchbender and all the great OSA people we have on here that helped me out. Thanks guys. You all are great.

ETA: Hahaha!!! I finally got a post off GC ... tee hee ...

99 suburbans with the 5.7 are bad on starters Mines a vortek and 4x4 and I'm on my 4th starter. just glad I bought the one with a lifetime warranty and saved the receipt in a special file.

My last starter came with an interesting piece of paper called TT-116-7TB
which talks about a bunch of starter problems being caused by a crankshaft position sensor causing high cylinder pressure.
in case you have any problem in the near future.

This ... a bazillon times over. When I met GC he would always buy the cheapest part he could get away with. Apparently his ex-wife didn't see any need for lifetime warranties on automotive parts. I am the exact opposite ... if they offer a lifetime warranty and you don't ever intend to sell a vehicle why WOULDN'T you get the one with the warranty.

BTW, GC tells me our suburban is just like yours ... This is the first problem we have had but we've only had this vehicle for a couple of years now ... Thanks for the heads up.

And to the rest of you guys who PM'd GC with suggestions and posted here, thanks a TON!! I can't make pumpkin bread for EVERYBODY, but do appreciate ya'll's help ... I either of us can ever return the favor all you gotta do is PM one of us ...

Here you go

File In Section: 06 - Engine/Propulsion System

Bulletin No.: 00-06-04-014

Date: April, 2000

TECHNICAL

Subject:
No, Hard, or Slow Start, Backfire or "Kickback" During
Crank/Start, "Grinding" or Unusual Noises During Crank, DTC P0338
(Replace Crankshaft Position Sensor)

Models:
1999-2000 Cadillac Escalade
1995-2000 Chevrolet and GMC SIT Models
1996-2000 Chevrolet and GMC C/K, M/L, G, P Models
1996-2000 Oldsmobile Bravada
with 4.3 L, 5.0 L, 5.7 L or 7.4 L Engine
(VINs W, X, M, R, J RPOs L35, LF6, L30, L31, L29)

Condition:
Some customers may comment on one or more of the following conditions:

^ Backfire during crank/start
^ "Kickback" during crank/start
^ "No" start
^ "Slow" or "hard" start/crank
^ "Grinding" or unusual noises during crank/start
^ Cracked or broken engine block at the starter boss
^ Broken starter drive housing
^ Broken starter ring gear on flywheel
^ Any combination of the above

Cause:
A condition may exist that allows the crankshaft position sensor to command up to 50 extra degrees of spark advance during engine cranking only. This in turn exposes the engine to higher than normal cylinder pressures which may result in an inoperative condition to the starter drive housing, the engine flywheel starter ring gear, or the engine block at the outside edge of the starter boss.

Correction:
Inspect for a stored powertrain DTC code P0338. This DTC will NOT illuminate the "Service Engine Soon" light. If this code is stored, the Crankshaft Position Sensor, P/N 10456607, MUST be replaced and the remaining components inspected for damage (engine block at the starter boss, the starter drive housing, and the engine flywheel starter ring gear).

Notice : When DTC code P0338 is set, failure to replace the Crankshaft Position Sensor could result in repeated inoperative conditions of the starter or flywheel.

Important : Some flywheel wear is normal; broken or missing teeth and/or cracks, are not normal.
