Ok, since you added the word "not" it makes more sense. LOL Carry on...

This 1994 Mustang Gt is used, it will not rev above 2650 rpm the mechanic said the fuel pump was bad, so we changed the pump and filter and also coil that was checking bad and the fuel regulator was also replaced, the funny part is it starts great and idle fine??

 

[CarsRus01]

The only think that has not been checked is the plugs and wire the cap looks new

 

[CarsRus01]

Does the car have a MSD box?

 

[CarsRus01]

no

 

[CarsRus01]

This 1994 Gt is just about stock just duel exhaust

 

[desertcox05]

is the spout connector installed?

 

[CarsRus01]

SPOUT connector that is found on the passenger side close to the Air box. The plug is most of the times a GRAY fuse like thing that's inside a connector on a wiring harness. I will check this

 

[CarsRus01]

thanks for the help, will post if that fixes the problem

You could try pulling the mass air flow sensor and spraying cleaner on it, worth a shot and only a few bucks for a can of cleaner.

Were the codes pulled?

What happens when you hit 2600 RPM?
Does it matter if the motor is hot or cold?
How was it determined that the fuel pump and/or regulator were at fault?

 

[can95droptop]

how many miles is it possible the cats might be plugged. I had this happen to me once before if you unhook the h-pipe and see if it revs over 2600 with just open headers. that would tell you if its the cats if not possibly the infamous distributor.

 

[94opalgt]

possibly the infamous distributor.

NO, We purchase this mustang used last week, the fuel requlator was all ready changed, the fuel pump was not holding pressure good , or low pressure
