No-Start, 1991 5.0 Cougar


Science Abuse

Recommended Posts

The car is having some trouble coming out of its winter hibernation. It went in starting just fine with its Braille battery. It has come out turning, but not firing... unless jumped.

 

The Braille gives it about 12.5-12.9 volts, which is enough to turn it convincingly for about 10 seconds, but it wont fire.

Jumping it gives it 14.3 volts, which fires it up. Charging systems pumps out 14.5 volts. Revs up to the top without a miss, though I haven't had it on the road and under load.

 

Notes:

-It had very little gas in the tank, which obviously didn't last the winter. I added 6 gallons of 93 and some octane boost. Since adding the fuel, the car has idled (at 2000rpm) for a total of about 20 minutes. I would think it would have pulled the new fuel through the lines by now.

-Plugs, wires distributor, everything related to ignition is at least 9 years old, apart from the starter solenoid which is a year old.

 

It's due for plugs, any recommendations?
