Your problem was probably right underneath the ignition coil (you almost got it)
A common failure on this vehicle (3.8L engine) is the ICM (Ignition Control Module)
First, you need to see what you are missing, (Spark, Fuel Pressure or injector pulse) in order to diagnose the reason for your...
SUV???
How about providing the vehicle information, (Year, Make, Model) if you would like a legitimate answer, because without the vehicle info. you will get a bunch of inaccurate guesses.
The Ehow thread is for programming the RKE (Remote Keyless Entry) Transmitter (Key fob)
What you need is the TDM (Theft Deterrent Module) Programming procedure.
Unfortunately This vehicle can only be programmed with a Factory GM TIS software or can be done by a locksmith with the correct...
I think you should leave it where it is, because without moving the CMP (Camshaft Position) Sensor, all you are doing is making the PCM (Powertrain Control Module) think that the Camshaft and Crankshaft are "Out Of Sync"
I don't know where you heard this from but it doesn't make sense to me.
You mean TL S-type.
Not without taking the vehicle to a certified technician for a "Used Vehicle Inspection" This is where the vehicle is completely inspected from bumper to bumper.
The Technician/Shop will advise you on any potential problems, repairs needed, and if it was properly maintained...
First place to start:
Scan the PCM for any stored DTC's (Diagnostic Trouble Codes)
When was the last time the timing belt was replaced?
If the Camshaft and Crankshaft are "Out Of Sync" the ASD relay will not energize and you will have no spark or no injector pulse (Fuel into the engine)...
You are correct.
The EGR (Exhaust Gas Recirculation) valve is a common issue with the 2.0L Mazda.
NOTE: The valve will sometimes hang open by a piece of carbon.
You have a Spark issue.
Most common thing on the VIN "W" 4.3L is:
1. The distributor cap and rotor.
2. Check the white wire at the ignition coil connector, and follow it back about 3-4 inches and check the wire for an internal break.
From your description, this sounds like a failed TR (transmission range) switch.
NOTE: The shop that you take it to MUST have the latest EURO software or they won't be able to access VAG (Volkswagen Audi Group) address words to perform a successful repair! Better get it fixed right away or...
You have the VIN code "K" 5.7L in your GMC. (TBI engine)
Was the vehicle "Pre-Conditioned" before you checked the timing? (coolant temp. above 160 degrees, Idling in park, with the EST (electronic spark timing) bypass wire disconnected)
The ignition timing on the K motor is "0" degrees TDC...
This is a common problem on the Tribute/Escape! The COP (coil on plug) coil packs are prone to cracking of the housing!
Also there is a TSB and a Recall on the PCM reflash TSB 04-07-07
Need to know if it is an 6"I" 2.3L (4 cylinder) or the 6"S" 3.0L (V-6) ?
ADDED: thanks for the additional information as this does matter on this vehicle,
The Mazda Service manual says this code is: Key on or engine running; and the PCM detected that the Battery Positive voltage circuit...
I hate to tell you this but you are going to need a transmission. There is NO electrical issue that will cause NO engagement in manual low or reverse! The IPC (instrument panel cluster) is another issue (ALL GM trucks have this problem sooner or later) send the unit out for refurbishing because...
