Check the engine coolant temp sensor. If that's off, the computer will supply the wrong air/fuel mix. Also, check for vacuum leaks

Could be a crankshaft postion sensor ,have you tried that ? Or some other sensor that is an input to the PCM , one that receive voltage from the PCM's five volt reference circuit . Do you know what that is ? Like the TPS - throttle position sensor , It has three wires , one is five volt reference , one is ground to the PCM an the last is the signal to the PCM . All three wires come from the PCM . If the sensor starts to go bad it can short an bring down the five volt reference circuit shutting down the engine . The MAP , ECT , TPS ,EGR , Check for five volts at the TPS after vehicle shuts down , the gray wire , if less then five volts you have a problem in one of the other sensors . First let the TPS connector connected an back probe the five volt circuit , is it 5 volt's ? If less ,disconnect the TPS an see if it changes . I hope I'm getting this right . There are videos on youtube . 5 volt reference How to check the 5v reference circuit for short to ground Cadillac

Your belt tensioner is not repairable. That doesn't mean it couldn't be repaired if the correct parts were available, but they are not. The tensioner is replaced as a unit.

Have your TPS sensor check (throttle position sensor) and also have the iac motor checked(idle speed control) Both are located on the throttle body

did you replace it with a new starter or a wrecker starter, maybe a bad starter. check the teeth on the flywheel they maybe damaged causing the starter not to engage. you may have to shim the starter. were there any shims when you pulled the original starter off.

multiple answers for this question ,need more detail ab how this prob came to be , u can pullthe stick and smell the fluid to see if overfull , burnt fluid will have a distinguished smell , back of trans will have a vacum line ran to modulator and this could be prob if tranny has given no warning sighns

check for fuel first spray starter fluid down throttle body if it starts could need fuel pump

check your idler control valve(motor) this valve controls idler an low speed it is located on the throttle body

Not enough air flow. Change the air filter, Clean the throttle body with brake clean. Along with the mass air flow sensor if you have one.

hhve you taken it apart yet?? the sliders may be frozen

i think you have the rong elecricale cords
or batterys or its oil

May have ruined the fuel pump
