I know that this will sound crazy, but it worked for me. I had my tb analyzed at autozone(for free) and found out that it needed a higher temperature thermostat. i changed the thermostat and the "service engine soon" light went out. No problem since.

You can disconnect the battery for 1-2 minutes and then re-connect it. The only thing is that if you haven't fixed the problem, the light is going to come back on. Have your vehicle scanned for the trouble code and post it on here. We can help you from there.

You threw a lot of parts and money at that thing guessing what MAY be wrong with it. Check any fuses that may be marked start,ign,etc. Do you have spark? The engine size would alos help.

2000 blazer runs rough after gas tank was overfilled

there is a vapour purge line from the tank to a charcoal cannister. The line& cannister has been contaminated with liquid gas. When the engine attempts a normal purge from cannister it gets loaded with raw gas, causing rough running and cherck engine light. Replace cannister. Never over fill gas tank, especially on hot sunny days

When the ABS light is on when driving there is a problem in the anti lock brake system and you will need to have it tested to find out what the problem is. As long as the light is on the ABS has been shut off by the computer until it is repaired. There could be problems with one of the wheel speed sensors, wiring or the ABS pump. On some vehicles the red brake light will come on too.
