I have a '88 5000s that is very difficult to start when the engine is
cold. The temperature outside yesterday was 24 degrees (f) and it took
me about 8 minutes to start the car. I crank it for a good 2 minutes
before it seems it is getting gas. It is harder to start than my old
1980 volvo diesel. Also, a warnng light came on that I don't understand.
It is a circle with dotted lines on either side surrounding it. Any
answers or suggestions would be greatly apprecited.

 

Could be that the temperature sensor (between 1 & 2 spark plugs is bad
and not telling the ECU that it needs to run the cold start injector.

or

The cold start injector (back top of the intake manifold) could be bad,
clogged, not getting power or bad ground. The bad ground is fairly common.

Vacuum leaks?

New fuel filter, air cleaner and plugs are nice.

When it started did it have black smoke coming out of the exhaust for a moment?
This would indicate a rich fuel mixture. This problem could be caused by so
many problems. With out hands on it's like pissing in a fan to guess. I very
rarely even respond to this type of ? because it's not practical. I'm a very
methodical trouble shooter and have been doing it for a 23 years. And without
checking the car out..it's a waste of time to respond. The light sounds like
it's the front brake pad warning light <if it's yellow>. This would indicate
worn out brake pads or a broken wire running to the sensor on the pads.

Good luck,

Rick
