Have Jeep Questions? Ask a Jeep Repair Expert for Answers
Hello and welcome to Just Answer! My name is XXXXX XXXXX I can assist you with your question.
Please allow me to ask a few questions in order to better help resolve your concern
Are you looking for some possible causes?
causes and solutions
I can help with that
Do you know if the engine has spark when cranking it over?
it will "start" when I spray starting fluid in the intake
Got it! Thanks!
And what is the fuel pressure at when cranking the engine over?
low to zero I do not have a gage to check actual pressure. I was thinking pressure regulator but want to get second opinion
Have you checked power to the fuel pump?
yes. Some additional infor the jeep sat in my garage for some time and was started monthly, and one day it just cranked and did not start.
How much power is going to the fuel pump?
with in the range Chilton says,
And what would that be?
I just verified it was within the range I did not write it down but could go check it again if needed.
yes, please do
ok one sec
ok well that was not good, my son broke my multimeter cannot check it
Ok, then you will need to get another one to check power to the pump
ok will do that but will have to go to store
Did you want to wrap up this session now?
I guess that is it until I get back
So what should we do?
well I guess close this session unless you can give me some other things to check
I sure can
If there is no power to the fuel pump
then we check the fuel pump relay and inputs
The fuel pump relay should have two powers and one ground while cranking
from there, it will activate and send out power on the forth wire
to the fuel pump
Keep in mind, the computer grounds the fuel pump relay
ok so I guess we are on hold until I get the new meter
so if there is no ground from the computer, then we check to see if the computer is "awake"
The reason I am telling you this now is so that we can close out this session like you have requsted
Sounds good! I am glad I can help
