what in the world would make a z just quit while running down the raod ? It has done it to me 3 times . i talked to a "mechanic" and he said that it was the key egniton but i changed it ! and it still does it ! the fuel presure is dropen to 35 psi after it starts, is this right ? when it is not running it is at 41 . the book says 42 to 47 psi .but it does not say if that is running or not . also the oil presure drops under 20 after it is hot, would this kill the motor?

 

your fuel pump may be bad
