I need to know what the timig should be on the 91 4.0. I know it's not adjustable but I had to replace the cam sensor and need to know what it should be at to put the distributor back in. Ichecked all the sensors with a computer and they all heck out fine except the temp sensor readds a little high, but it won't start. so I am going to try the timing again i had it set at 0(zero) but it's not workig.
