intermittent ignition problems with 1990 Montero - 8/25/2007 8:48:55 PM    stevez   Posts: 6 Joined: 8/25/2007 Status: offline My 1990 Mitsubishi Montero has the V-6 engine. It cranks well. When it runs, it runs well, but will stop without warning occasionally. More often than not, it won't start after being run and then shut off. When it won't restart, no spark is present. No engine codes are showing. Does it sound like a coil issue or the power unit on the bracket next to the coil? This is my girlfriend's primary vehicle...please help if possible! Post #: 1

I found one at O'reilly for under 100 bucks. Its not a factory part, but hopefully it still works. Everything else is seems very high dollar. As far as the ECU going bad, wouldn't it throw a code?Thanks again for everyones help!!!!! (in reply to stevez) Post #: 6

RE: intermittent ignition problems with 1990 Montero - 9/6/2007 7:57:20 PM    stevez   Posts: 6 Joined: 8/25/2007 Status: offline Well gentelmen, I put the new ignition coil in, and that was not the problem .it still does the same .It starts fine and runs fine until it heats up. when I shut it off, it does not have spark.I think it has to do with the heat, and I believe it to be under the hood,since that is where most of the heat comes from.What is a TPS, and what does it do. Also, how about the ignition control module?Any ideas?Thanks everyone for your input. (in reply to stevez) Post #: 10
