Struggling to start would suggest either a lack of compression or a fuel related issue. The smoke was most likely unburnt fuel.
Air getting into the fuel can cause the engine to rattle a bit as it starts to run unevenly. Giving it throttle probably didn't do anything as it's an electronic throttle and if memory serves me right has no effect on start up. Couple of things to check: - Fuel: Has it had a fuel filter change recently? Check it's a decent one and fitted correctly. - Compression: Easy way to loose compression is via loose injectors, which cause all sorts of noises. Run the engine and look at the injectors, if they are loose you'll see them moving. - Coolant: These engines don't really loose coolant, so check the expansion tank and cap, hoses etc. for signs of leakage.

The cylinder head temperature sensor will cut fuel flow, causing a mis fire leading to the engine cutting out, if it goes over temperature. Just because you're offended doesn't mean you're right.

My wife and daughter were driving home one night in the 2.4 when it started cutting out while the temperature gauge would read high. Turned out to be losing coolant and the engine is designed to cut out to avoid damage. My daughter would put water in the coolant reservoir and they would drive on until it stopped again, got topped up and cooled. When they got home I found one of the clips on one of the hoses had shifted allowing coolant to escape. I changed the clip, I topped it up and purged the air and we never had any bother since. The cut out due to rising temperature stopped the engine getting damaged. So check for a leak where your hose clips are. 1982 88" 2.25 diesel

Thanks for the replies,I can't remember what the temperature gauge was showing but the coolant was very low. Does anyone know if the gauge have to register as overheating before the sensor makes it cut out? If it was that sensor, what does it actually do, does it cut the fuel or is it something else? 'm just trying to figure out what seemed like the lack of compression initially when I tried to re-start it. Thanks again for the suggestions.

CHT cuts in before the temp gauge moves and yes it works by cutting the fuel supply giving the impression of fuel starvation. Just because you're offended doesn't mean you're right.

If it was due to coolant being low, and no obvious leaks around rad hoses etc, check the heater control valve at the top of the bulkhead on the near side. If faulty when switched to hot and the engine is at temperature you can get a few drips from the valve that will reduce coolant over time. While on cold during the summer it won’t drip. So it’s hard to spot as you don’t get a pool of coolant under the truck to point to the leakage location.
Re topping up coolant. If it’s the original orange coolant you can get a litre of concentrate from the dealers, then get some deionised water from your local supermarket, it’s real cheap from them as people use it in irons. It’s not the cheapest option from the dealers but you do know it will be compatible with what’s in there already if it’s not been changed before or if it was changed by a dealer. |

Is your passenger or driver's footwell wet? Maybe it's a leaking heater core. Coupled with the recirculating valve, this can lead to coolant loss even without leaving puddles under the truck. If all your engine cooling system hoses are OK, then the recirculating valve and heater core should be your next suspects

Thank you for all the input. Just an update- The coolant leak was traced to the EGR cooler. It has been running fine ever since, no repeat . No fault codes showing when it went to the garage for checking over, so still a bit of a mystery as to what happened last week.
