I have a 92 F150 supercab and it wont start...I had someone jump

Not sure about the Ranger but the Ford Galaxy used speakers of around 6 - 8 inch diameter.

I suggest you remove a door card to check rather than try to estimate from the size of the speaker grille. This is because best practice is to make the hole significantly smaller than the speaker.

Sorry I couldn't give a definite answer, I just thought you should hear from someone...

Check the fuel filter, spark plug /wires,or timing.

Probably your alternator.....Test with the car running and battery fully charged.....Use a multimeter.....battery should be over 14v....if not have alternator checked out

does it crank over and not fire if so check for spark if tou have spark check the fuel rail for a tire valve looking device if cap is still on remove and press shrader valve while someone cranks engine if you have no fuel spraying out of this in great volume check fuses for fuel pump try swaping fuel pump relay with horn relay if these things do not work look under or just above carpet line on passengerside floorboard in center area near heater box for the inertia switch if red button can not be pushed unplug and jump plug with small wire and crank over if it starts this is your problem if you do not hear fuel pump at this point fuel pump is bad

It's either leaking out of the line from the M/C to the slave or it's leaking out of the slave

Will it turn over while being jumped? Most likely the starter is going out.

under the distrocap under the rotor bug

Sounds like a bad starter relay. Try that first.
Good luck, dont forget to rate.

has to be a relay to the injectors. try to hook in your own hot wire to "jump start" the system.

Drain and refill with the proper fluid, and keep truck out of deep water. There is no trans. cooler on these manual trans. vehicles, so there is no chance for contamination.
