Well I got my new computer and my check engine light is finally working!So now,the motor turns over,the fuel pump is coming on spraying fuel,I have spark,but it wont run.If I dump extra gas down the throttle body it want to start up but it wont.If I turn the key without dumping gas in the TB it wont kick over at all.I have no codes coming up.So far I replaced the starter,ign. switch,ign. modual,computer.Please any ideas would be helpfull.The truck has 77,564 miles but sat for over 5 years.I also drained the gas tank,cleaned it out and put in fresh gas.I must be missing something
