1997 Grand Am Pontiac won't start

have you checked the rocker switch

Do you need a new motor

How would someone know that?

You need a wiring diagram or at least
match up the cut wires,solder & heat shrink them

Then diagnose the motor,switches,etc

I buy factory wiring diagrams for all my vehicles
I never approach the vehicle without them
One quick check of what does work,then into
the wiring manual

You can not repair something you know nothing about,
need reference material

Helm.Com ---for manuals & lots of money

Have you checked the door switch?

ok first did you push brake to move shifter?

do you mean it won`t crank over then it could be the starter.check for voltage at the large wire terminal this is the battery feed wire directly from the battery.then check for voltage at the smaller terminal while someone tries to start the car.there should be voltage at this terminal only when trying to start.if both of these test are good then you will need a starter motor.the starter is located at the rad side of the motor were the motor bolts to the transmission,at the bottom side of the motor.if you mean it cranks over but won`t start then you need to check for spark at the plugs then check to make sure you have fuel with the proper pressure.a quick way is to spray carb cleaner into the intake while someone tries to start the car if it starts then you have a fuel problem,and you will need to test fuel pressure.

well does the key go in does it turn to the start pos? if the dash dost power up its because the switch is bad if it will power up but not start it can be becuse of the resitor chip depends on what is going on if you cant get power its becuse of the switch

no that wont keep it from starting have the starter checked

I would start by replacing the Crank sensor and the cam sensor.

Hello! When you swapped the engine, did you have the PCM (Powertrain Control Module) from the new motor as well? If not - you will need to have a "CASE" learn run on the PCM that you're currently using (the one from your previous engine). Important note: the 1997 Grand Prix GT's and GTP's have quite a few differences from the 98-03's. The CASE procedure is run using the Tech II tool and can be done at any dealership in about 10 minutes. If they aren't sure what that is, suggest to them that they follow the procedure for DTC 1336 - Crankshaft Position (CKP) System Variation Not Learned. :)


Hope this helps and good luck!

That sensor is called the Cranshaft Position Sensor.
