CHECK THE FUSIBLE LINK THAT COMES OFF THE STARTER POST.THEY LOOK JUST LIKE A WIRE, BUT THEY GET STRECHY WHEN THERE'RE BLOWN.IF THIS IS THE CASE YOU WILL NEED TO FIND THE CIRCUT THAT CAUSED IT TO BLOW,AND REPLACE THE LINK.

94 chevy s10 4.3 litre engine wont start. Its getting fuel and spark. pretty much everything is new. sometimes after a while i can get it to run. when it does i can drive it anywhere and its starts ri


might pull that cap again and see if the dist. shaft is loose
(side to side play) Sometimes the bushing wears out and the
magnet will hit the pickup,makes the spark irratic.Should have a new rotor with the cap,they also go bad.

Driving 60mph power drops as though out of gas. Coast 2-300 yds pump gas pedal van back to normal. Now at home it starts then stalls, will only run 5-10 seconds. New plugs&wires distributor cap and...


signs of a bad fuel pressure regulator. the vehicle runs rough, the engine will not start usually in the mornings. many times engine starts but stalls shortly after starting. a bad regulator can result in fouled plugs. black soot on plugs, blake smoke from tailpipe, running rough, stalling. you could have residue in fuel tank and need to change fuel filter again. have a very good day !!

Truck starts then when engine gets warm it dies


Try removing the petrol cap on the tank, if the truck runs ok then you have a blockage in a hose somewhere.(vacuum created in fuel tank)

1999 Ford Taurus mechanical problem


Hello,
your problem appears to be the idle control motor located on the air intake manifold it is a small motor that goes bad quite often. Other items that can cause this is a bad /clogged air filter or a tune up (spark plugs and wires), or clogged fuel injectors. to clean the injectors you can buy a container of fuel system cleaner and pour it into the gas tank and as you drive it cleans the system.

Once the fuel system is cleaned via a tankful of cleaner & gas then the idle controller motor would be next on the list to be replaced.

Good Luck !
