    Do you know the engine code? On your OBD1 diagnostic port take a wire and jump the two last pins in the top row with the ignition on. The check engine light will flash a few times then pause then flash a few more. It will repeat the cycle. Count the first flashes, they represent the first number, then count the second set of flashes which represent the second. You'll end up with a two digit number representing a certain issue. It shouldn't be too hard to find the issue that goes with the code on the internet.

Possible Service Engine Soon Light, Engine Stalling, or Hard Starting

Engine, May 18, 2009

RepairPal Expert Overview:
The RTV seal on the fuel system control modules may allow water to enter into the module. Water in the module can cause a short, which may cause hard starting, a crank-no start condition, or stalling, and the Service Engine Soon light may come on. If the engine stalls unexpectedly, there is an increased risk of a crash. Dealers will replace the fuel system control module free of charge. The recall began on May 18, 2009. The GM recall number is 08411.

Changed fuel pump. Fuel pump does not come on and it's not the relay. What could the problem be? Was driving down the road and the engine shut down, but still turns over, just won't crank because...


do you have ignition fire? does the check engine/service engine soon light come on when when you turn the key on? can a scan tool communicate with the ECM? there are several things to check if you have no power to the fuel pump because the fuel pump relay is controlled by the ECM.

Check dist. cap and rotor and replace. Just fixed one last week. Rotor was causing a misfire under load and coil contact to rotor was worn out down too the cap. Graphite dust from the center contact in cap was all over the rotor causing a misfire. $25.00 in parts or less. While you are there replace wires and plugs. Autolite ap25 plugs 2.99 each

As I was driving down the road, all at once 4 warning lights came on my dash at once (Check Engine Soon, Service Engine Soon, ABS, & Trac Off Indicators). What could be wrong, the car still ran fine...


It's most likely going to be the wheel speed sensor which is located at the wheel bearing. when they become disconnected or the wire breaks your abs and traction light will come on and something your check engine light.

Service Engine Light staying On


Alot of times a voltage drop to the O2 Sensor can cause your check engine light to come on. Even tho the O2 sensor is wrong fine.
