Stalls when turning the air conditioning on SolvedSolved

Ford Escort 1997  97367 miles
When turning the air conditioning on, the engine goes crazy: speed suddenly drops to 550 rpm, and then raise to normal, 750 rpm. I have already checked if it has code OBD2 and it indicates that there are no code errors.The idle speed has been cleaned and the PCV valve checked and replaced. I have noticed that sometimes this failure appears even without the air conditioning being turned on, but it is less noticeable.

Wiring problem with negative battery cable

Ford Escort 1998 Ford escort zx2 2.0 DOHC 185000 miles
On the negative battery terminal there is a block with five wires attached to it. I think these wires serve as a ground for the fuel pump, ECU, and speedometer. Well one of the wires has twelve volts witch in turn is blowing fuses. They are the radio, heater, turn signals, speedometer, horn and rpm gage. I've had the alternator rebuilt and replaced the constant relay module. Dang car is still blowing fuses. Does anyone have any input on this

No injected pulse

Ford Escort 1999 Sohc 4 cyl. 100000 miles
1999 Ford escort. Have feul pressure and spark at spark plugs. But no injected pulse. Pretty much checked everything still no start. Checked wiring and ground connections. Even tried another ECU still nothing. Replaced cam sensor still nothing. Was going to change crank sensor but It does have spark. Could the crank sensor still be at fault?
