Look at the fuel filter. May also be a bad fuel pump.

several CAR products had a torque converter lock up problem. It would shift in and out at a certain speed. Sometimes changing the transmission fluid will fix it.

it could bealternator problem
It's the same as on any other car. If it's starting to go, you may notice a drop in RPMs below normal, when slowing. When you go to start it, it may not want to at first and may seem like the battery is going dead. Lastly, at night, when you turn your headlights on, if anything dims greatly, or lights lightly pulsate, these are all signs. The best thing to do is to take it up to an Autozone or something like that and get a battery and alternator test.

My # 30 fuse keeps blowing... 99 Mercury Cougar

If it is a 7.5 amp fuse, it powers the charge warning light in the cluster and applies voltage to the alternator to make it charge.
You will need someone to trace that circuit and look for a short to ground. It may be in the cluster or in the harness.
Something else besides the fuse is making the car not start.

Have you ran an Oil pressure test? low oil pressure (20lb)or no oil pressure(0lb)and the lifters will not open the valves enough to let fuel in to the cylinder to start your engine!

How do i replace the power steering pump on 99 cougar

Generic pump removal:(1)Start your job ONLY with GREAT lighting,so you can see spacers and objects which might get pinched,etc.
(2) Pry over the tensioner and loosen and remove drive belt,NOTING how it installs(some cars have a pic of the drive belt routing under the hood).
(3) Remove both hoses and hang up with wire or duct tape out of the way.
(4) Remove mounting bolts carefully(mark which ones go where),knowing that there are sometimes spacers that you must KNOW from whence they fell out.
(5)Pull out the pump or take it down under to get it out(different models).
(6)Take the pump to get the pulley pulled off it by the Parts dealer.
(7)Re-install the new pump,and be very careful to use proper torque plus 10% or so.Use blue locktite on any bolts you think might loosen up later.
(8) Fill up the pump to a low level and bleed out by starting the engine and turning the steering wheel fully left for 5 seconds and to the right fully for 5 secs. then refill to proper level and do again. don-ohio (:^)
