Fuel Injection

I have a 1998 4R Auto 4cyl with 110,000 miles that is giving me a fit. It acts flooded and wont start until the engine turns over several times with black smoke coming from the exhaust. I discovered I can turn the ignition straight from off to start and it will start ok, but if I turn it to on and then to start it will be hard to start. Any one have any suggestions? Thanks

    You might pull the spark plugs and see if one is fouling up. That would suggest one leaking injector or a very bad spray pattern.

    A scan tool hook-up would also be a good idea, to test for things like coolant temperature sensor.

    Thanks Mr. Shiftright. I suspect I've got a dose of crud so my next step is to change fuel filter. I parked it last fall when we left to Snowbird for the winter and I left it with a couple cans of injector cleaner in the tank. I'm anxious to get back home and try it. Evidently Toyota didn't switch to OBD II because my scanner wont connect..

    Well some scanners have trouble connecting but a 1998 Toyota is definitely OBD II. Maybe a friend has another you can give a try. You can also check to see if your scanner works on a different car.

    If it does, then you might check your fuses. Does the CEL light come on when you first turn the key to "ON" (not starting the car?)
