Can I put diesel engine in 190E year 1989? Thanks for your advise!

Two types were used .On this engine ,but not both together. One was round wth 4 round contacts inside ,And one that is colured green, i think if i am right .This has two contacts .Both on the top of the block on the inlet side of the head at the back.Removal is just to unscrew to extract it, If your not sure and dont know get firther help .

FUEL IS LIKELY IT. THE CHEAPEST TRY IS THE FUEL PUMP RELAY. FUEL PRESSURE SHOULD BE CHECKED

is that a diesel ?? if yes then on the injection pump sometimes there is a solenoid that goes bad and it doesn't let the Injection pump to cut the diesel that is being pump to the injectors.

hi, i have seen this problem ten years ago twice, but i was dumbfounded by the answer. all details aside, I replaced the ecm, and never had the problem again with both of them. this repair was a recommended repair by the local truck depot in my town, they stated the ecm got hot along with the truck and it lost the injector sensor signal. now, don't take this solution and run with it, i haven't repaired a 6.2 diesel in ten years and i maybe off track completely. but at least maybe you could ask around your town or maybe a large truck facility about this. of course, you should take to a shop to have diagnosed. hope i could help.

If you go to the auto parts store,the strut and the bearing plate will run close to 150 dollars each,and the bearing plate has a bearing in it to allow for steering.

well m8 they got ya bonkers eh? the fan isnt cheap by no means but you can change it yourself save ya sum quid that way the fam usually runs around $80 usd

first the a/c issue is probably due to low charge. Need to recharge, if you still had R12 in there you need to have it updated to R134A or find someone who has R12 which is tough.
Starting issues are tough to explain without more info but if you mean your starter doesnt turn the motor I would suggest a new battery as you probably have a weak one or it has a bad cell. If your starter turns but it wont start could be the OVP relay, the cold start vale or any number of ignition parts from the coil to the plugs.

perhaps this is is a good start..will look around more for you also..good luck
