Engine died and refuses resuscitation[ALL/1998] posted by Mike O'Bryan on

Any help on this one would be really appreciated....
I have an 84 240 DL with the 2.3 liter 4, with a manual transmission and approximately 123K mile on it. The engine died and I can not get it started again. It rolls over fine, and has a new battery. I checked it for spark, and fuel pressure, and it has plenty of both, the camshaft is rolling over, so therefore the timing belt is not broken.
Events leading up to its untimely demise.... I took it on a business trip to Wisconsin in Jan. It was really cold that week (high temps were in the 'teens) and the car would run really rough as the choke began to pull off until it was up to operating t emp- however, I attributed that to the really cold weather, and a choke which might need adjustment - however, it had not done this before.
The car sat overnight and started fine in the am. Drove it for 20 miles,and then stopped for 20 minutes. Restarted the car, drove approx 1/2 mile, and as I was coming to a stop the engine died, and I could not get it started. Had it towed to a local sh op, they checked it out and could not find anything wrong, however, the car started up again. I picked it up from the shop, and approx 35 miles later on the expressway, doing approx 60 mph it died again, and died for good. I rented a car hauler it towed i t home and it is now sitting in the garage.
This one has got me stumped, any suggestions?

Did you check the fuse box for signs of corrsion? Also, if it's 84, it should be Lh Injection - check the main fuel system fuse in its holder on the right side of the engine compartment. Next to the relay block. I always hear garage stories about 90% o f Volvo tow-ins being related to electrical faults. That's where I would start first! Which distributor does it have: Bosch (orange cap) or Chrysler (white)? If it's the Chrysler, you could have a hall-switch problem. I went through misery trying figure o ut a similar intermittant dying of a 82 wagon. For what it's worth, check fuses first.

Mike, This could take awhile. Go ahead and ck the fuses 1st as the other guys said. I doubt thats the problem in this case but it only takes a minute. Are you getting spark to the spark plug. If ok at coil but not at plug, you could have bad rotor or d ist. cap. How are you checking for fuel? If you have spark or if the fuel pumps run then the hall switch in the distributer is working. If the fuel pump runs the fuel pump relay is working, and the under hood fuse would have to be ok. The mass air flow se nsor is not likely to cause your paticular symptoms. The eng. coolant temperature sensor could make it run very rich or lean, but probably would not kill the engine at 60 mph. I,m not sure how to direct you from here with out tools you may not have. Fuel pressure should be about 250 kpa. If the fuel regualtor sticks shut the pressure will go high enough to flood the engine but again not likely to cause your exact symptoms. A likely possibility is no or too much injector drive. With the engine being cranke d, you should have 12 volts on 1 side of injectors and a pulsed ground on the other. This is best checked with a noid light. I think thats the correct term. Its basically an LED that plugs in in place of the injector. Depending on the results of this test you could have a bad LH control unit, a bad fuel pump relay, or a problem in the injector harness. You mentioned a choke. Your car should have MPF injection with the choke factor being controlled by the LH cont. unit. If you have and over seas Volvo and actually have a carb and choke, I'm lost. You need fuel, spark, and compression to run an engine. Compression is usually not intermittant. If all of these are there then you probably are not getting the correct amount of fuel. If you can check any of thes e things further and come up with more details, let us know. Robert
