I have a issue with my 95 Saturn. I can start it up and drive it for about 5 to 10 minute before it acts up.
I can be going down the road and it will die instantly. No cutting out, just a straight shutdown. Its like someone hit a off switch. After it dies it will not start again for at-least one hour. I had my friend come out and hook a machine up to it since i have failed to combat the issue. I changed the gas filter and hollowed out the cad convertor thinking one of those options would fix the car. Neither one did.
I received 3 codes:
Code 26- Driver Module Fault
Code 27- Flag Quad Driver Module Fault
Code 48- Info Flag Reference Pulse Error

Anyone know if any of the three codes could be without a doubt causing the above described problem


EDIT
Also i was told to maybe look into the Coolant Temp Sensor .
I have noticed that the fan never kicks on.

Thanks

 

The QDM is internal PCM that controls various components from check engine light to cooling fan to EGR solenoid & pugre solenoid. If it comes on as soon as you start the car most likely the EVAP purge solenoid is the fault.

Thats a guess not a fact, maybe stopping at the dealer will save you money in the long run.

 

I paid 9 bucks for the Coolant Temp Sensor and changed it out and it seems to fix the problem.
Thanks

 

Maybe you read this sticky post

i thought i had this problem put in the bag, but i was wrong! It ran fine for a couple hours then the same problem came back.
Could i possible have a weak fuel pump? After the car dies it wont start immediately and it back fires when i attempt to start it. If i let it sit for an hour or so it will start right back up as if nothing is wrong.
This car is really starting to wear me slick.

 

check

cooling fan relay
A/C clutch
CCP Solenoid (Charcoal canister Purge)
EGR solenloid
Coolant hot light
Upshift/Shift to D2 light
Speedo Operation
