Starting troubles

From : bg

Q: 1992 b250 van 318 cu - very low miles twice over the past year which is about all ive used this truck after about an hour at 75 -80 mph drive the truck would not re - start when it was shut down for a brief stop. it acted like the ballast resistor was going bad almost firing up but not. do they have ballast resistors anymore checked error codes nothing other than the o2 sensor but im sure that isnt the problem. anyone seen this before bg .

tbone wrote because when a cold fi engine is first started it is in open loop mode and the inputs from the o2 sensors are ignored thanks tbone. as you know i am not good with newfound fi or emissions technology grn. ill look up how open loop mode works. and stick to the old models rach .

why stick to the older models when the new ones work so much better. -- if at first you dont succeed youre not cut out for skydiving tbone wrote because when a cold fi engine is first started it is in open loop mode and the inputs from the o2 sensors are ignored thanks tbone. as you know i am not good with newfound fi or emissions technology grn. ill look up how open loop mode works. and stick to the old models rach .
