1991 mitsubishi might max hard to start when its cold out side.the colder the harder.now it wont start at all and its real cold!

Sounds like tire separation. Don't drive with that tire on the truck. Put on the spare and have it checked by a tire shop. Good luck.

if this is carb motor than it needs a manual choke that mounts on inside of lower dash, the kind you see on lawn mowers,,,push and pull.

you can get pressure specs from your local parts dept, and check injector signal with a noid light

drive it in the summer duh

That is how the automobiles work. hard to start when cold.
Of course if this is not normal for you, maybe a new battery might help.

Next time when cold and it will not start remove a spark plug or two and see if the engines flooded. If so there are two things that come to mind; 1, worn injectors, leaking as engine sits with time causing difficult starts 2: bad oxygen sensor, if failed engines tend to run rich and the ECU may have your injectors pump heavy amounts of fuel to keep from running lean; often times you'll see poor fuel MPG if O2 sensor failed.

I hope this may have assisted you,

Per my Chilton's manual tehe bolts should be (cold engine) 65 to 72 FT. Pnds., the cam shaft bearing bolts should be 8x25 = 15 - 19 Ft pnds and the 8x65 should be 14 - 15 Ft Pnds.

The sequence is as follows for the (10 ) head bolts:

7 - 5 - 2 - 4 - 10

9 - 3 - 1 - 6 - 8

I hope this may help,

could be coolant temp sensor

I recently replaced the ECU in my 91 mighty max. If you remove the glove box you will see it on the right hand side.

sounds like dirty fuel check your fuel filters see if ther blocked
