98 Saturn Starting Problems

Once car gets warmed up..Stop at store come out 10 or 15 minutes later...
Motor turns over but will not start...Does this on hit or miss
intervals...Driving me crazy...Saturn diagnostic says fuel pump,pressure
regulator, rail, & injector codes....Replaced pump and regulator so far
but with no luck...HEllllPPPPPP

 

Once car gets warmed up..Stop at store come out 10 or 15 minutes later...

Coolant temp sensor failure can cause a no start condition when the car is
hot......

 

I came across this problem with a 99 Intrepid. All the garages were making
her spend money.. 1000 bucks in about 2 months..

I narrowed it down to the Crankshaft Posisition sensor.. When cold the car
would start and run perfectly.. as soon as you turned it off it would not
restart.
The CPS sensor was failing when hot..

so she spent 1000 bucks when it was not needed. this repair only costed 12
bucks.

 

we had that same problem with ours. it was the sensor. it is located
right on the front of the motor and is really easy to change.

 

Which sensor?
