I've replaced fuel pump, filter, injectors. Etc.
even took off intake manifold. Cleaned the intake ports all the diaframes. If I ajust the Crank angle sensor until it sounds like all is trying to fire. Then with the gas pedel to the floor it kicks in but does kick all the way over. Is timing of with injectors sparks all. I can't find any data on what the crankagle sensor should look like on the inside of it.
HELP

Hi sviney,

Thank you for the donation and sorry for the delay iin answering. This is a vehicle that not many people have much experience with, me included. Anyway I will try my best and hope it is good enough.

There are no diagrams to show the inside of the crank angle sensor that I can show you bu you can test the resistance of the internal coils.

Crank Angle Sensor
Remove sensor connector. Note terminal identification. See Fig. 8 . Using ohmmeter, check resistance at specified terminals. Resistance must be within specification. See CRANK ANGLE SENSOR RESISTANCE SPECIFICATIONS table.
