1990 Jimmy TBI won\'t start, please HELP! It's got 113,000 miles (supposedly). Started and ran perfectly up until yesterday w/ minor puff of smoke for 1 second when cold. Today it turns over fine but no hint of starting. I had my brother crank it while I looked at the injectors and saw no fuel, Should I? I will check the fuel filter but was wondering if it could be anything else simple. Any help would be greatly appreciated. P.S. I am new to Fuel Injection.
