So my 87 240 has an issue starting in the cold weather. Yesterday was less cold than today and it had trouble starting but eventually did. Today it is firing but it won't actually start. I recently replaced the in tank pump, fuel pump relay, amm, fuel/air filters, and I have a full tank of gas. I read some things about a cold start injector, but I don't know how to test if it's bad. Any suggestions would be lovely.

If my car were to start, it would run fine and probably start back up after I turned it off.

If the earlier fixes don't take care of the problem, try pressing on the accelerator just enough to barely move the throttle plate when it starts to fire.

At -15F and below my '87 245 needs a little more air to get it to run when it is very cold. After the first start of the day, it is fine.

Disconnect the AMM and try and start it. Maybe the one you replaced recently has failed.Cold start injector on an 87? Not that I am aware of.

Ah, that's why there was nothing on it anywhere. And I have two AMMs. so I'll put in the other one and see. I also have a few possibly unrelated symptoms.

-the car runs hot sometimes. Not ever in the red, but close to it. We changed a radiator hose and it helped a bit but sometimes I'll look down and it's up there again. Then in five minutes or so it's regular.

-I read this thing about "bucking acceleration" at stop lights and mine did that yesterday but it made this weird cracking sound. Kind of like when you crack a glow stick to make it work just more metal sounding and louder.

-Sometimes it dies around corners as if it's out of gas (even w/ full tank).

When it used to do that, it was the distributor every time. I kept having to replace them when finally Ned, the volvo mechanic/genius, said that maybe putting these "little metal condoms" around the wires in the ECU wire harness would fix that. -it did. (I guess this story isn't really relevant, but if anyone has this problem in the future, that was a crazy life saver.)

"Disconnect the AMM and try and start it"
Disconnect and reconnect with key out of ignition. AMMs don't like electricity through them while being connected/disconnected.
