Yes. All 91 and newer 4.0's have sequential injection with both a cam and crank sensors. The cam sensor is a hall effect 1x signal mounted inside the distributor just like the obd2 4.3's chevys. The crank sensor is also hall effect and reads off notches in the flywheel. The number of notaches (3 sets of 4 notches) are not compatable with any gm system I know of, but mounting a new wheel and sensor on the front puley looks pretty easy.
