check for codes, if none then check fuel pressure and volume with a gage. pressure should be in the area of 35lbs unless this is throttle body which is about 15/18lbs pressure, if this is a vortec motor the pressure is 55lbs. the volume should be about 1 liter in 15 seconds. the vortec injection systems have a problem with the spider fuel lines that go to each injector cracking/breaking causing no fuel supply and leaking into the intake manifold and not going into the cylinders.
Try a bigger battery or a battery charger.swap it to give enough power to start the engine. If that doesnt work than try checking the starter solenoid at your local auto store
is it blowing black smoke. if so it may heave bad temp sending unit. there are two . the two wire unit tells the computer to adjust fuel at the right temp.your vehicle feeds more fuel to a cold engine and cuts back fuel as engine warms up
black smoke is flooding( uncontrolled injector operation
run the fault codes to determine the problem area ( ECM , fuel pressure , faulty injector control, MAF/VAF sensors or failed heated oxygen sensors
i have a supercharger in mine and if i run less than superios gas it will do this as well, good bet use shell premium gas and that should stop if it doesnt try replacing your fuel filter its just under the body of the car at the front edge of the driver side door :)
Check the fuel pump reset switch again, if it is popped back out then replace that little switch in the trunk, any ford one will do. it works off a magnet and a bearing to close the circuit for the fuel pump. easy fix.
