hi, i have read through some starting problem post. and i did tried some of the fix but still no go...

here is my senario. before the starter broke from the repetitive cranking..

when i try to start it does crank but wont really go all the way.. when it first happend it did not start in the day but did start at night when i gave it a try.i drove it around the block and made a few stops and it works good.. so i think it is the main relay. but the next day it wont start again on during the day, (btw i leave in florida 84 deg) so i change the main relay. still wont work..

today i check the distributor and everything is ok.

any ideas.. i think im getting fuel cause i can hear a humming noise for a few seconds. spark plugs looks good. havent check the sparks but the plugs itself looks good... battery does have good voltage i even have another battery and check it still no start...

any other ideas...

i cleaned my fuel rails to...

thanx

 

The humming sound is your fuel pump pressurizing the system. It does not automatically mean you are getting fuel to the cylinders.
