Was on a short trip with my '89 240. Was running fine on the trip to my destination. On the return trip it stalled while driving and would not restart. It turned over and would occasionally, momentarily start, but would not stay running. I checked fuses and in particular the under the hood fuel pump fuse, which appeared to be OK. I recently (within the last 2 yrs) replaced the crank position sensor and the in- tank fuel pump. I had the car towed to a relatives' residence and I rented a car to return home. I need to go back to get the car home which is about 160 miles away. The car does have the pink label computer. The fuel gauge was at the 1/8th level. Any ideas on what to look for? I do have running 93 240 from which to take parts.

Hi Clang2,

Bummer. I'm not the best guy to help you here, but nobody else has come forward so I'll take a shot. hopefully someone will correct me if I'm wrong.

You don't say if you can hear the main pump operate for a few seconds with the key on before cranking. The in-tank pump is not audible.

From your limited description, it may be a fuel problem and I would firstly want to know if the pump is working. If it's kicking it's likely you have spark.

If the pump is not operating, it could be the relay, the ECU, the pump itself, or any of the connections between them. Your pink 561 is suspect because it's been known to fail by not grounding the relay which powers the pump.

I may be wrong but I think you can eliminate both the ECU and the relay by jumping the fuel pump directly from the fuse box.

If possible, have your relative connect a jumper wire between fuses 6 and 4 with the key out. They should be able to hear the pump running under the car. If it is running, have then try and start the car with the jumper in place,and report back.

If it runs, you can drive it home like that, but you'll need to remove the jumper each time you stop or you'll drain the battery.

Thanks for the reply. I have since solved the problem with the info I received in the past. This problem was different in that the car was kicking over occasionally. I did test for the main pump running and as it turns out, it was running occasionally. When I returned to my relatives (about 160 miles away) the car started on the first try. I replaced the pink label ecu with a white one, replaced the fuel pump relay and the cps, just in case. I drove the car to get a gas fill up and returned to my relatives. I went out later and the car would not start. I tested the fuel pumps by jumping the fuses and the main pump would only briefly if I would thump it. I did have a spare to install and was able to return home. The last time I had a problem with intermittent no start I replaced the pink label with a white one, but later found out that the culprit was the cps, so I put the pink label back in. I'll leave the white one in this time. Thanks again for the reply and the info. It's good to know that I could have driven it home with the jumper in place if it was not the fuel pump.

Hi clang2,

What Peter maplebones says.

I was also waiting for others to reply before me.

I see your post history you've had this problem before about four years ago.

With the comprehensive help you got in reply, you may want to review the wise guidance you have there.

Check the OBD codes, also? (I've not read through the afremention post of your from four years ago.)

Hope that helps.
