My 91 deville will start and stall out right away,I have checked fuel pressure,replaced the control module,checked all fuses and relays,and checked for codes.I heard of a hall module may be my problem from a local parts store,any advice out there will be very nice.I also have a 1993 Allante,is it the same procedure as my deville to check for codes(through climate control)Thanks in advance for any tips.
Could be bad TPS adjustment. Will the car start if you depress the pedal slightly? If so, I'd check this item. Your TPS may not be set up to let the engine rev up when first started (too far advanced).
wont stay running even if i depress the accelerator,almost seems like it is cutting the fuel supply,or whatever tells the injectors to fire is not working.Do these cars have a cam/or crank position sensor?this all seemed to happen after the serpintine belt flew apart,I have looked to see if anything got unpluged by the belt but i have yet to see any sensors on that side of the motor.
