What year did they start putting computers in jeeps?
YJs started using computerized carburetors in 1987 (first year of production), and If I remember correctly went to fuel injection in ’90 or ’91. and I believe the 1987 XJ (Cherokees) 4.0. L I-6s were the first with fuel injection (not certain about the GM v-6’s).

Why does my Jeep Wrangler have no cel?
The whole reason for that is a) symptom number 1; no CEL means no codes either while the problem is on going, and b) even after you get the jeep started, the computer only sees this as a normal start once it gets power, as if you had just turned the key on right then instead of 10 minutes ago.
