will this sensor not being pluged in keep the engin from starting

 

no, but it will run like ***** what year, engine, TBI , TPI, ... ect

 

91 3.1 v6 i think its mpfi

 

do you get a security light on the dash?

 

yes but it goes out after about 2 seconds i have pictures of alot of the wireing on another post

 

hook a test light up to an injector plug, try to start the car watch the light if it flashes the ign modual and the injector circuit are working, check fuel pressure at the engine, could be fuel pump or plugged filter whats the miles on the car??? over 100K most likely the pump

 

it has a new pump and it has 92,000 miles on it

 

ok check the injectors to see if they are getting power, should pulse

 

how would i go about doin that .. and i toggled the fuel pump and it works but i much rather have it work the right way i have a whole nother thread that may help with the explanation on the problem a lil more

 

its the very weird electrial problem thread

 

as stated before GET A TEST LIGHT!!!!
