Sounds like just too low compression. This will keep it from starting. Do a compression test and wright down the reading. Remember, when it's warmed up, the heat has made the cylinder expand a bit so the compression is going to be down. If the rings are warn out, that will drop the compression even more when it's warm. Fence the no start when warm.
C190 is a 2.0 L OHV 8V engine same as marine 4AA1.
when warm did you try diesel test fuel?
runs now , right, or runs and stalls. right?
that be the biggest clue there.
besides black smoke.
lost compression hot.
or lost fueling hot.
simple test for compression and test fuel....... leaving what?
I had the exact problem with my 1993 chevy c1500. I found that the IAC was sticking so the engine would die at idle after warming up and the ignition module was pulsing the ECM intermittently after the engine warmed up so the fuel pump wasn't being turned on after the engine died....I replaced the ignition module and the IAC valve and all is good. I don't know if testing the ignition module reveals that it isn't sending pulses to the ECM.
Chances are its something electrical, but thats a big list. You'll have to rule out a few things and check for spark and fuel pressure when it won't start.
injection system may have air in it dont know much about this model try cleaning spark plugs by warming them up on a gas cooker not to much just warm clean them and try that might just be damp plugs but it sounds to me that there could be an air blockage in system some ford models diesels are notorious for not starting when the run out if possible check to see if there is any way you can see if there is any fuel getting to carb of inj system
hi if your car starts fine when cold but then runs rough when warm then wont start this points towards the oxygen sensor ( or lamda sensor for its proper name) being at fault, if your sensor in the exhaust comes before the catalytic converter then i would say its the sensor at fault how ever if the cat comes first then it could be that that is at fault. your best option would be to have a diagnostic check done so your not wasting monery buying parts you might not need.
let me know how you get on or if you need further assistance ok
thers a oil psi senser that wont let the fuel pump run at low psi when the car worms the psi gos down ,the fuel rely only runs the pump for about five sec as a primer then the oil psi senser takes over thirs a plug righi behind the oil fliter for the senser ,un plug it and put ajumper wire across it as a test ,you may need a oil pump
