1993 mitsi lancer 4g93t cd5a, installing manual boost controller

I'd be looking at crank position sensor

Hey have you tried disconnecting and re connecting the battery? my mitsi carisma startd doing that so i rang up dealer and aparently they do it when the computer thinks there is something wrong with the engine, so it enters slow mode (or turtle mode or something) so that minimal damage is done while you drive it slowly to yr mechanic. Could be complettly wrong tho. Good luck.

if one of the plugs is fouled neither plug will fire

change your pcv valve its clogged and not leting positive crank case pressure release.

First you need to check all your fuses with a test light. The 12 volt light switch wire for the ilumimation of your gauges is just a park light feed, the best way to find it is using test light,it can be found in radio plug or park light switch or fuse board.Your check engine light is not so easy ,first I would check the bulb in dash, then you need to make sure of you lose wire tap connections the check engine light needs a feed to it to come on you need to check your aftermarket ecu wiring diagram to see where this is or get hold of a factory one to find it to see if you can manual trip it with test light.

first thing to do is remove spark plugs and if they smell really fuely you will need to change them if that doesnt help you will need to get the microtech tuned for a good coldstart , this depends on if its running stand alone or as a piggy back
cheers.
please leave feedback.

yea sound like turbo problem get rid of it

9.3 is a really dead battery - replace it and check the alternator. I have seen them go bad with no dash indication. As to the oil being black, you may have worn piston rings, and probably need an engine re-build. Worn rings allow the exhaust of the engine contaminate the oil - you should also see increased oil consumption due to the vapors exiting via the PCV valve and being burned in the engine.

Check your plugs & timing. Full service.

Replace the coils under the spark plug cover.
