In some applications a check engine light is triggered by the odometer. Requires the dealer to reset. If no ODBII faults are present, the only sensors that are subject to physical wear are the TPS(throttle position sensor) and the 02 sensor(oxygen sensor). These 2 sensors are relatively cheap and should be replaced due to age(2000). To maintain optimum performance, I do 3 things, every 30,000 miles. 1) Change the Air Filter. 2) Replace Fuel Filter and 3) Add a can of B&G44K to a full tank of fuel. The B&G is the best on the market and will condition your fuel pump and injectors. It is available only through dealerships(11.00 a can at Toyota) and should not be substituted. These 3 things are your path to cheap performance and fuel economy

Standing at front of truck, looking under the hood.

The closest cylinder to you on your right is #1. #2 is close left. #3 is middle right, #4 middle left. #5 is back right and #6 is back left.

Firing order is 1-6-5-4-3-2. This is the sequence for placing the wires on distributor cap in a clockwise direction. #1 spot on cap is the 3rd post after the wiring harness (clockwise). This post should be closest to cylinder #5.

Process of elimination of possible faults. A code read might provide a short-cut but otherwise bear in mind an engine needs fuel, spark, timing and compression to start and run and with modern cars the immobiliser must also be considered when one or more of those things are absent.

Hi Jim:
Is it possible that when the gasket was replaced, the timing may have been changed? Check it with a timing light.

It will need to be done with special programming tools and software s well as a subscription to the ac delco database.this will run you a couple thousand dollars. Spend the couple hundred bucks and send it to either a dealer, a shop that has the equipment, or find a mobile company that specializes in flashing ecm's.
