Hi All,
Tried searching but couldn't find an answer so hopefully someone can help me with this.
Have a 1991 Corsica 3.1 MPFI that has just started cutting out. There is no hesitation, rough idle, surging, etc it just dies. The frequency of the stalls increased rapidly so that now it cuts out after about 5-10 mins and can not be restarted for about 1/2 hour.
Have not checked fuel pressure with a gage but it appears healthy when the schraeder valve is depressed and a timing light indicates a spark on all cylinders when it is cranking. There are no eror codes.
The odd thing (to me) is that once the engine cuts out, while the key is still in the on position, various relays, the cooling fan and the check engine light all flash and click off and on as if they are shorting out. The radio and dome light are unaffected.
My question is.....would a faulty crankshaft position sensor affect the entire engine electrical system like this?
Thank you in advance for any input!
