was the engine getting fuel or was their no spark ----need to establish if fuel or ignition problem ---running out of fuel may have damaged pump -deadspot -overheat ---problem with relay need to check and test the system ---
Clogged air filter ? Needs air into the engine also ,plus compression . Are the fuel injectors spraying fuel into the engine ? Try spraying starting fluid into the engine through the throttle plate and seeing if it starts then ? If it does ,fuel injector problems .
have the fuel pressure and volume tested with a gage.this sounds and acts like a fuel pump problem.check the fuel filter as well and replace anyways.when it won`t start but cranks can you hear the fuel pump running.listen at the fuel filler neck with the gas cap off.if you can`t listen under the car at the fuel tank you should hear it running/if not hit the gas tank and if the car starts then the pump needs replacing.you should check to make sure you are getting spark at the spark plugs to eliminate an ignition problem but i think its fuel.
So you have used the Noid lights to see if the computer is pulsing the Injectors, and you have GOOD Kv on the spartk minimum 25-30 Kv's?
Also it might get gas but how much gas? you need to perform a volume test there is a certain amount of fuel the car needs her minute to sustain demand load variations.
Is it port injection or thortle body? What engine is ? if its port injection your fuel pressure is to low , if its a throtle boty i think 15-18 is minimum to keep the car running, might have a bypassing fuel pump in the tank.
my '93 f-250 (4.9L) stopped running while driving, now it acts like it isn't getting any fuel. Tried switching tanks, but still does the same. What would be the problem.
Gas line filter may be dirty and clogged. Change it. There could be sediment or dirt in the tank that you drew up to the filter when you ran out of gas and it has built up and is blocking gas from getting into the engine.
If the car has over 100,000 miles on it, you may need to replace the distributer. I don't think the bad gas caused this issue I think it may just be a coincdence. But if you already changed the plugs, wires, distributor cap, and rotor, I would definetly check the distributor.
