Welcome! My name is XXXXX XXXXX I will do my best to assist you with this problem.
im sorry your having this problem
fuel pumps are the most common problem causing a no start and will act like its out of gas and or the fuel pump not running or low fuel pressure
but there are a few things we can check for to find out why it is not starting for you
do you have any carburetor cleaner or starting fluid on hand ?
I did prime the carburetor with gasoline. Did not start. I do not have any carburetor cleaner or starting fluid.
this engine needs spark, fuel and compression to run
you confirmed spark so far
if you pull out a spark plug is it wet with fuel ?
do you have a test light ?
The test light showed that there is spark. No I did not pull out a spark plug to see if it is wet. If it is wet, then what?
if its wet either those plugs are wet and fouled or the compression is low
if they are dry we need to check for an injector pulse
Those plugs are fairly new and the wires are new.
do you have any access to a compression tester?
if it has spark and you can confirm fuel pressure with a fuel pressure guage key on engine off @ 60 - 66 psi and holds
then you are down to compression low, fouled spark plugs
since it will not run by adding fuel the odds are its not lacking fuel
So if it is not lacking fuel is it mostly likely fuel pressure. If that is the case, how do I bring up the fuel pressure?
I am not with my vehicle at this time but I will do what you suggest later. If the psi is not 60 - 66, does this mean that perhaps the fuel pump is weak? I have replaced this fuel pump before, about three years ago.
yes if the psi is under that then the pump is more than likely bad
also make sure the fuel filter is new and not plugged up
