My son and I have been trying off and on for over a year to get a 1982 Volvo running correctly. Somebody had messed with it before, so we don't know what is really fouled up by time and deterioration or by a little dangerous knowledge.
Anyway, we had it running so it almost purred like a kitten. Drove it back and forth on our dirt township road, around a small turnaround in our yard without a problem.
So, decide to buy the current license plate stickers and get a full tank of fuel. The perverse vehicle ran perfectly for about 3 miles after a gas fill. Then the same old sputtering etc which seems to indicate a fuel pump or fuel relay or a fuel system control module or something we have not found on the circuit diagrams yet.
Then there is the 1990 Jeep. It mostly runs now after a lot of fiddling and fixing to make driving it better. Shock absorbers, motor and transmission mounts, etc.
But, it would sometimes start instantly, and then we would drive it a few miles, park it and then we might have to click the ignition start key off and on 20 or 30 times to get the fuel pump to kick in or whatever. I was also hearing a ticking whenever the ignition key was turned on.
So, after talking to a good mechanic with more experience than we have we ordered a fuel pump relay and an engine control module. Well, as soon as those parts got here, we have not been able to get that Jeep to not start and the "ticking" has disappeared.
If new vehicles weren't to damned overpriced and old junkers so cheap and we actually had some money, we would not be messing with these vehicular conundrums. We are now playing with using very low power 12 Volt LEDs
join in tracking strange or erratic behavior without requiring a dozen test instruments. Stay tuned. Radio Shack had a few of them on hand.
But, I expect we will keep plodding along as if this is just one more solvable cross-word puzzle built with nuts and bolts and perversity.
