Its a 3.0.Im sorry took so long to get back to you. This site rocks as i figure out how to use site.The starter went out replaced it. It cranks over now. But sometimes starts runs very short time and dies.Sometimes it turns over hard.Sometimes it whirls over like no spark.Ive cleaned ground cable and body ground.I just ordered a new engine electrical control relay for it. Because it seems to stick for long time and then clicks.I wish id checked this again sooner. Some great ideas some ive tried some i will be doing in the morning.I have been doing my homework when theres time. Junkyards in this area dont have no 89 raiders with 3.0.Ive been looking for that litle blackbox on coil bracket with no luck.One dealer said parts cant be ordered.But did find dealer says can order that little blackbox on coil if i order factory coil comes on the bracket 259.00.WOW Still cool vehicle. Thanks for more ideas.Try them and see let you know.
