strokemanche Posted March 27, 2013 Share Posted March 27, 2013 Alright I have a 88 Comanche that had a ba/10 in it. And as you probably guessed it met its demise. Unfortunately I couldn't find an ax-15 for Decent price so I went with an aw4 out of another Comanche. I did the engine harness swap but the problem I am having now is it won't turn the starter over. All my relays come on along with instrument luster but it won't turn the starter. Did I miss a safety switch somewhere? I know the neutral safety switch on the trans could be the culprit but I'm worried there is something else missing. Any help is appreciated.

mvusse Posted March 27, 2013 Share Posted March 27, 2013 Try it in Neutral. If there is a problem with the switch itself and it won't start in Park, Neutral usually still works. I believe the engine harness to actually be the same between the two, but don't know about the transmission harness that plugs into it near the center of the firewall/oil filter/dip stick. Not trying to point out the obvious, but you will also need a TCU. Although even without a TCU it will still work, but you will have to shift it manually with the gear selector, and the torque converter won't lock up.

Eagle Posted March 27, 2013 Share Posted March 27, 2013 It almost has to be the neutral safety switch. Link to comment Share on other sites More sharing options...
dasbulliwagen Posted March 27, 2013 Share Posted March 27, 2013 There is a dissassmbly and cleaning procedure that can be done on the nuetral safety switch. It will cost you little or nothing and will be one less thing to worry about if it isnt the problem. Link to comment Share on other sites More sharing options...

strokemanche Posted March 27, 2013 Author Share Posted March 27, 2013 Tried it in neutral and nothing. And I have the TCU and all hooked up. This is why I am stumped Link to comment Share on other sites More sharing options...
mvusse Posted March 28, 2013 Share Posted March 28, 2013 You say you swapped the engine bay harness. Evidently there is either a problem in the harness, or something is not hooked up. Link to comment Share on other sites More sharing options...
92tanMJ Posted March 28, 2013 Share Posted March 28, 2013 Okay so I know when people go to auto to manual there is a two pins somewhere they bridge, it has something to do with the NNS. So I'm thinking maybe it could go in reveares like you need it for it to start...maybe someone else can better explain what I'm saying. Link to comment Share on other sites More sharing options...
strokemanche Posted March 28, 2013 Author Share Posted March 28, 2013 That sounds possible. I'll do some research and see what I can find on that. Appreciate it Link to comment Share on other sites More sharing options...
bowtieuser Posted March 28, 2013 Share Posted March 28, 2013 Will it start if you turn on key and jump across starter? with it in park or neutral with wheels chalked and a person holding brake of course (saftey first) Link to comment Share on other sites More sharing options...
dave92cherokee Posted March 28, 2013 Share Posted March 28, 2013 When you swapped the engine harness did it come with fuses and relays or did you have to swap them over? If it came with fuses and relays have you tried swapping over all your fuses and relays from your old harness into the new one to make sure it's not a blown fuse or bad relay?

mvusse Posted March 28, 2013 Share Posted March 28, 2013 88 Comanche has no fuses under the hood. Link to comment Share on other sites More sharing options...
strokemanche Posted March 29, 2013 Author Share Posted March 29, 2013 I know it turns over when I jump the starter but didn't try to run it Link to comment Share on other sites More sharing options...
mvusse Posted March 29, 2013 Share Posted March 29, 2013 Check the starter relay and it's connections. It is right next to the battery and acts as a power distribution point. Link to comment Share on other sites More sharing options...
bowtieuser Posted March 29, 2013 Share Posted March 29, 2013 This may be way off but what did you do with clutch switch? Did it go with wire harness Link to comment Share on other sites More sharing options...

mvusse Posted March 30, 2013 Share Posted March 30, 2013 Clutch pedal position switch was never in a Comanche, and didn't appear in the Cherokee until 1997. Link to comment Share on other sites More sharing options...
