I have a 91 cav with 3.1 liter. It has 45 psi fuel pressure, spark, injector pulse and the timing chain and pulleys are in good shape and line up properly. We have replaced the cam position sensor and the computer and it still will not start or even backfire. I was driving it when it just suddenly quit. Any ideas?
This question would probably get answered faster in the Maintenance Forum...I would say ask there.
Good Luck.
