1989 ford ranger EFI no start It has good fuel pressure and it will crank there is a good spark but the injectors are not firing what could be the problem was running fine then stoped at a big jolt?
either your injrctor pump is broken or your computer has quit
On a 1999 kia sportage 2.0 you have power to all wires going to the injectors at all times and when cranking injectors are not firing?
What makes the injectors pulse on a 1988 f150 It has fuel pressure and is firing but will not crank?
You might check the controller for the fuel injectors sometimes they can go hey wire you can use a multimeter and check it to see if it's firing in the correct order and if it's not you might need to replace it. Give that a try also check for shorts in the wires from the injector connector from the injector all the way back to the controller. Hope that helps. :)
