How can I get the engine to start

hi olga.
The starter won't crank. If nothing happens when you turn the ignition key to the "Start" position, it means that the starter motor doesn't turn over the engine. Most commonly this could be caused by a dead battery; here is How to check the battery. ... The starter motor itself or a starter solenoid could be bad.13 Aug 2013

NO START ??????? When you turn the key to the start position , nothing happens ? Or the engine spins an doesn't start an run ?

It's a electrical problem as when you turn the key nothing happens so first thing is get a multimeter and check the starter motor has power when you go to start the engine , check both terminals to and from the battery good luck colin

With out seeing the vehicle it could be a number of reasons, battery, wiring fault, starter motor, earth fault

check:
battery good 11 v min
battery conecctions cables, all clean
if automatic trans, in park or neutral selector
if standar trans, press the clutch pedal full down, check switch in pedal
the dash lights all on in switch on, check for antiefth extra
alarm disabled
and doors closed, seat belts
or crank start but engine no start need a full diagnosis for qualificated personal.

Clean and tighten battery cable connections and check battery ground, engine ground-should be a ground strap from engine to the body or frame. If this happens and you have nothing, no headlights, nothing-it's almost certainly a problem at or right off the battery.

How about corroded battery cables (internal)

Fusible Link wiring corroded & open circuit,does
everything electrical work except the starting circuit?

Turn key & have power to starter solenoid ?
Neutral Switch !
Ignition Switch !

Tough to guess without wiring diagrams,
to see where to start testing

Can't fix what you don't know you have

It may start the engine fine, meaning it has a good ground, BUT, the ground from battery to the body is NOT. Make sure that connection is good and clean.

I have a 2001 saab 93 and battery will need a jump in the morning but battery is new. I found a small fuse box next to the battery with 4 60amp mega fuses in it and when I remove the 1st 2 fuses the battery will be ok in the morning? can someone help

It could be the park/neutral switch, next time it doesn't start try wiggling the shifter in park while turning the key, or shift to neutral and see if that will work. if that doesn't change the problem I would replace the ignition switch.
