Shop Discount Starters

The 1 or 2 designates whether it's a single overhead cam engine or dual. It's part of the model identification.

Well... on the igjectors the back of the shaft has 2 lines

one for gas and one for air

maybe that helps

im not sure which # is it

cant tell

paper work on the car says sw

loooks like the job will have to be done from the bottom

Job well done....grab a cold one

You failed to mention that the intake manifold has to be removed to access the starter.

Eeek that doesnt sound like much fun at all.

Hi replaced starter in 96 Chevy Tahoe 5.7 v8 with new remanufactured starter. Starter spinning but not engaging they flywheel. Any advice?



I would not recommend buying a remanufactured unit.
You might want to spend a little more and buy a good new one.

Took the starter in got it tested it works fine and it is identical to the one I took off. They said it could be a bad connection. I made sure I had good contact on bothe connections. Battery was dead from trying to start it with the old starter. I jumped it with wife's vehicle and starter just spins and does not engage. I read somewhere that the battery not having enough power could cause this so I hooked it up to the charger and will try again. Battery is only about 7 months old if it still doesn't work should I try a new battery?

Charged the battery and the starter is turning the motor now but it won't fire and doesn't turn over long before the battery is drained again. try a different battery?

Charging and testing the battery should have been the first thing you did.

Ignited the battery was ok because it's not very old and this is the first time it's been discharged. I'll get it tested or get a new one to see if it resolves my issue. Thanks to all for the advice so far.

You can't look for any other issues in the electrical system until you have a known good, fully charged battery.

Battery charged and tested good. Engine turns over for a bit before hearing the loud clunk noise which I believe is coming from the starter again. I'm stumped. May have to break down and have it towed to a mechanic so it doesn't break this starter.

You may have bigger issues than that.

I'm starting to wonder if this may have the crank sensor problem. With low battery problem and possible crank sensor issue, it could cause the engine to kick back and possibly damage the starter. Some of them could even cause a backfire that blows the intake gasket out. I'd replace the crank sensor just as a precautionary decision.

There is a TSB on this:

Bulletin No.: 00-06-04-014

Date: April, 2000

TECHNICAL

Subject: No, Hard, or Slow Start, Backfire or "Kickback" DuringCrank/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).

No old starter would clunk once in a while then quit. Took it off to find part of the housing had broke off.

If the starter spins but does not engage the solenoid, it has a bad solenoid, plain and simple. It only has one trigger wire and once energized, both the solenoid and the armature engage so you have either a bad starter or a wrong starter. The wiring is pretty much a "no brainer". The only small purple wire goes on the only small "S" terminal.

Take it back and get another one. Sounds like the solenoid is bad.
