I have an 02 Mitsubishi Galant, for the last few months its been intermitantly giving me problems starting. When you would turn the key it would just tick, but after 2-20 trys it would, but other days it would start just fine. Well I had the stater checked and that was fine, but was told that my ignition switch was most likely going bad. Well this morning we changed it and now the engine turns over just fine but will not start! Please Help!
I have had a bad battery on a 6g72 Mitsubishi engine keep blowing my engine control fuse... and the battery was barely bad
There is no simple answer, there are to many variables.
If you have access to a scan tool, pulling the codes should help. Without them its back to old school hunt and peck method.
At this point we need to narrow down the problem. You need to test for spark.
Crank the engine for no more than 2 seconds at a time to prevent flooding the engine with gasoline.
If you have spark, You will want to make sure you have
fuel injector pulse, along with fuel pressure. If you have spark
..simply spray some starting fluid in through the air filter
and hold the gas pedal to the floor and crank it over while spraying.
If it fires up, you know it is fuel related( fuel pump, regulator, or
ECM if no injector pulse) .
If you have no spark then look at ignition coil connection and trace through to the distributor( if equipped ). The crank shaft sensor has a tendency to fail on these as well.
This should give you a few things to test and check to start you on your way to narrowing it down.
If you have no spark then look at ignition coil connection for power and trace through to the distributor( if equipped ). If it is DIS( no distributor). It may be the Crank sensor or the ECU. The crank shaft sensor has a tendency to fail on these as well.
The ECU uses the signal sent from the Crank sensor to trigger the spark and fuel injectors. ( make certain you have checked all fuses)
Its
a hot start issue.
Can
be related to low fuel pressure or problem with crank sensor.
Also
it can be weak battery or starter.
But
possibilities are to be inspected to confirm what exactly it is.------
