| Subject: | 1990 Mitsubishi Mighty Max |
| Question: |
I just bought a mighty max. When we got it home and went to start it the engine just turned over. Then tried it again and it started. It worked for a while and then did it again. This time we checked for spark and there was none. I read the notes on the ECM and replaced two leaky capacitors but saw no other damage. I checked the resisitance on the Coil and it was within spec (Primary 1.6 ohms and Secondary 11.4K ohms). Do you have any suggestions? Should I have the ECM sent in for repair or are there other sensors I should test first? |
| Answer: | Arlin, ECM problems are not easy to diagnose. If you just bought the car, getting it a basic tune-up would be best. If you haven't already, replace the spark plugs, plug wires, distributor cap, and rotor. Since your coil is within spec, it should be ok. Other items that should be replaced as regular maintenance items are
the air filter, fuel filter, PCV valve, and think about replacing the
transmission fluid. Start with the basics before you spend money to have
your ECM inspected. And if one of your sensors were faulty, your Check
Engine Light would most likely come on. |
