DO NOT USE THIS COMPANY Because they are a fraudulent company! The sensor they provide does absolutly nothing. I tried it and nothing changed in the way my vehicle ran.

SOURCE: Flex Fuel sensor Truoble Code

If your flex fuel sensor is bad there is a product on the market that is a much better alternative compared to purchasing a new sensor for over $600 or even a used one for typically around $300. The product is called a Flex Fuel Sensor Replicator made by T&S Electronics and can be purchased off their website The cost of the Replicator is $150 and it is very simple to install. In fact, your old flex fuel sensor stays in place so you don't have to mess with your fuel line. The wiring from the original flex fuel sensor is hooked up to the Replicator which sends an electronic signal to your engine control unit that "replicates" the signal the ECU would get from the original FFS when you are burning standard unleaded gasoline containing up to 10% ethenol.

The only limitation present with the Replicator installed is that you can no longer burn E85 or other alternate fuels (no big deal for most people). And, as an advantage you should see a 1-2 mpg improvement with the Replicator installed.

Yes. First, in the fuse block under the hood check INJ A fuse and INJ B fuse. INJ A fuse is circuit 1039 which feeds the coil. If the fuse is OK, replace the coil electrical connector. I stock 2 of these at my dealership because they are needed quite often.
FYI P1351 is an ignition coil control circuit DTC.

SOURCE: 2000 Silverado L/T Z71 4X4 Lubrication Diagram

Lube points should be: All moving joints in suspension. Ball joints, idler arm, tie rod ends etc. On 4X4's, all universal joints on drive axles (excluding C/V joints... just inspect boots) All slip-joints and "u" joints on driveshafts. Many of these items may not have zirk fittings on them from the factory. If the component has a plug installed, it should be removed & replaced with a fitting. If there is no place for a fitting, when the item wears out, the replacement will have a fitting.

SOURCE: PCM Troubleshooting Check light on with no code reader power

You can't jump the connector to get codes on OBD II. (Pre 1996) Try hooking back up you code reader. If it doesn't communicate, check the fuse for the cig lighter. This fuse should also power up the diagnostic plug.

Service engine soon light is on does not show any codes what could it be

The service engine light should only come on when the PCM detects a fault in one or more of the systems it controls. It should also store codes.
If a simple code reader was hooked up to read the codes perhaps the code reader is only good for the generic codes and your PCM has model specific codes stored in it. Some code readers cannot read those codes. A shop scanner may be needed to get codes.

2000 lincoln town car wont pass smog yet it is running clean. mechanic states he has to checkodes? is this expensive and what could be wrong any suggestions?

Checking codes is an Industry standard description for checking the PCM (engine computer) for DTC's (diagnostic trouble codes). Retrieving codes from the PCM is not hard to do at all, but a code reader or scanner is required to do so. The hard part in diagnosing the trouble code is finding the exact cause, and depending on the cause, it can be expensive or possible a simple fix.

Check the fuses. ECM/Pcm.

PS if you have an old scanner that is a code reader ( older than 2000) That is the problem.

2000 grand am se abs light an trac off light and service engine soon light stays on, but i got the car scan and no codes come up

If you had the car scanned with a generic OBDII code reader (Which is what they use at all the parts stores) this is probably why it is not showing any codes. You have "Vehicle Specific" codes. This means that the problem with your Check Engine light is not a problem that will generate a "generic" OBD code. A generic OBD code reader will not read codes from your Antilock Brake System or your Traction Control System at all... You need to have it scanned professionally by someone who has the proper equipment and software to access the Controller Area Network (CAN) in your vehicle.

It could be that your knock sensor circuit is working perfectly.You may have a knock that it is reading for long periods.
Try running it disconnected, and see if there is a clatter or knock when accelerating lightly.

You could have a vacuum leak.

Gm check engine codes P0 606 2007 2500HD. What does it stand for? How can I fix it?

Powertrain Control Module processor fault. It means you are going to have to replace your PCM. You can try to find one at a junkyard, because the dealer will charge an arm and a leg for it.

i hope this helps,
