20 Most Recent 1989 Mitsubishi Sigma Questions & Answers

We do not have any info on motorhomes, if you know what chassis this was built on you can look it up that way.

If the shop can't find it, you need to check the wires. Make sure you check if the engine is getting fuel. Check the engine for spark. If those check out, test the igntion system. Cam sensor and the crank sensor. Check all fuses. If everything checks, check voltage to the wires.

Try a high powered magnet, like the kind attached to the back of really big speakers.

should have no advance at idle ignition timing is 5-7 degrees with the vacuum advance line plugged

2 degrees before TDC is the best setting. Slightly more advanced (1 degree or TDC) will work if your gas is really good quality.

Click on the following free Link. It has the Timing Belt/Mark Diagrams you will need for your 1989 Mitsubishi Sigma.
You can count the number of notches on the Belt giving you the number of chain links between the Front and/or Rear Camshaft Marks to the Crankshaft Sprocket.

Let me know if this helped....

personally i disconnect the battery before doing it, but others seem not to, no idea why though!

hi could be a fualty flasher unit or a bad earth

Is it white,black or blue smoke?
If it's the org. engine it will has over 200,000 miles on it.
It's normal to has the valve stem seal/oil seal on the head to leak oil into the cyclinder.
The smoke you see is the motor oil drop from the seals. It land on the top of the cyclinders and it create black smoke at start up.
The inexpensive fix is to start using high mileage oil with seal conditioner.
This will help soften the rubber seals and help reduce internal oil leak.

The correct fix is to wait until it's time for a head gasket replacement and let the professional to service the head.

Complete head service is the only method to stop this internal oil drip problem.
I will monitor the oil and coolant level.
White smoke AFTER warm up is the first sign of blown headgasket.

Hey nake sure your timing is correct or also that ur glow plugs are still holding on strong there is also a few other problems it could be like ur fuel injecters cud be blocked or your injector pump may be leaking or sucking air!!! best of luck hope it help alittle!!

possible faults - *check the shifting cable selector is aligned with the neutral starting switch * check engine mounts *make sure the fluid level is between the marks on the dipstick running hot * overdrive friction and drive plates have worn out * the torque converter or oil pump has a problem *do a torque converter stall test hope you used only mitsubishi automatic oil when changed *check the throttle position sensor * temp sensor for the auto the TCU has faults or needs to be replaced
