Ok well in addition to my 03 GT I have a 1992 Toyota pickup with a 4cylinder. The engine has been rebuilt. It cranks fine in the.morning but after i drive somewhere.and get back in all it does is spin over. It won't start. It has to.sit for least 2 hours before it will crank again. Its really irritating. It has New distributor cap spark plugs wires battery alternator fuel filter and tons of other New parts. It has a exhaust leak before the 02 sensor. I just ordered a long tube header Im hoping having that fixed will help something possibly get the right amount of exhaust to the sensor. And it sputters sometimes when i drive and the check engine light comes on and off each time it sputters.or hesitates. Please feel free to.offer advice. Thank you all!! Oh and when it won't crank it will sometimes start by rolling it sometimes that won't even start it.
