Died at the Drive-thru...

[Boston]

Have we eliminated a bad alarm ECU?

Hey Boston, can't say that I have...how does one check for a bad ECU alarm?

[Les Parker]

Do you have a spare key?

If so, trying locking and unlocking the drivers door 4 times, that should reset the alarm

Thanks Les, I do have a spare, I'll give it a try after I get the other broken key extracted from the ignition and replace my battery.

Good news/Bad news...1st good news, got the broken key extracted from the ignition. 2nd good news, battery tested just over 12volts so I replaced it with a fresh battery, reset the ECU and the truck fired-up fine w/ no M&S lights flashing & no check engine light, purrs like a kitten. Bad news...when I step on the accellerator the rpms increase but will not return to idle even though the throttle body is in the idle position??? There are no codes so I'm not sure what it could be??? Maybe MAF?? Anyone??

Did you solve your problem? Your issue (with the exception of not returning to idle) sounds like a crank position sensor. The M&S lights were probably related to low battery voltage.
