1991 240 wont start

[Raven]

I have a sedan that wont start. It started up then died about a minute
later when I tried to give it gas to warm up, just barely touching the
pedal. Now it wont start, when I crank it it will try but will not fully
catch. Any ideas what may be wrong?

Lots of things come to mind.

Gas tank empty.
Fuel pump relay.
Fuse.
Crank position sensor.
Other ignition related stuff.

Can you hear the fuel pump buzz under the car? Only runs for one second
after you release the key, when trying to start it.

Unplug the wire from the air mass meter and see if it starts then.

Unplug the wire from the air mass meter and see if it starts then.

And if it does, remove the flexible hose that leads to the throttle
body, and look for cracks and splits in it. Very common on the 240s.
Otherwise, James is implying that you have a bad air mass meter.

You need to isolate the fault, obviously, and there is a systematic
way to troubleshoot.

First, find out if the problem is electrical or fuel.

I have an inductive timing light, but any timing light will do: hook
it up and have someone crank the engine over while you look for the
light to repeatedly flash.

If it flashes okay, your problem is fuel related; if not, it is an
electrical issue.

..... Also re the Air Mass Meter, remove the plug, spray the contacts of both
the plug and the socket with contact-spray, then push the plug in and out
ten times. (This isn't black magic................ I got it from a Volvo
dealership tech.) Finally coat both sets of contacts with dielectric
grease..

Good Luck.
