My 1993 Laredo backfired and then died the other day and won't start. It will turn over, but won't fire. I have replaced the CPS and it still won't fire. Anyone with ideas on what I should do?

Try the cam sensor, but first check and see if you have voltage at the coil primary plug and a pulsing ground at the plug, if you have voltage but no pulsing ground, then you need a cam sensor. It is located under the distributor cap.
The MAP sensor will not cause a no spark problem.
