my truck was running just fine after radiator was replaced. in the dead heat of summer, reaching triple digits consistently, truck dies. sat for a week, wouldn't start still. cranks but doesn't turn over. after another week or two, first time trying to start, cranks and starts and runs for a bit. tried driving, dies after about 30 sec of driving. started again right there and drove fine to a friends house and back couple miles away. then on, started and died on and off going to work and back for the next week. trying to leave work, truck wouldnt start at all and even battery got a little tired of repetitive cranking. whenever it was running, there was no loping or misfires, sounded completely normal. i need help bad please. trying to find the most inexpensive way to fix this. broke college kid that needs some decent help!
