My car's electric system puts out about 10-11 volts to the accessories and I was wondering is there any way to check the system using freescan? I know I probably have a bad ground somewhere and I want to avoid checking every electrical connection in the car. I have already checked the battery and alternator and about 10 over connections and I am stuck.

 

Anyone tried to do this before? is there a way to check voltage on components through the pcm using a program like freescan?

 

No!

 

well that doesn't help. so i guess i have to get out the old voltmeter and check everything?

 

is there a better way to do this?

 

How did you know your only getting 10 to 11 volts to your accessories? How much did your altenator put out? You don't have an underdrive pulley, do you?

 

no underdrive pully. i do have pcmforless. i tested the accessories with a volt meter. they are at about 10.6 volts. i have a brand new optima battery and a high output alternator (140 amps i think). i had both of them tested by an auto shop and they told me they were more than fine. i am thinking it could be a dying fuel pump but i guess it could be a ton of different things. i am just wondering what the likely causes could be? is there any ways to find out with testing everything?
