You have a restriction in the fuel system. did you check the fuel filter? that pressure is way too low to be right.

C200 Merc 2009 model, engine turns but car wont start, why


same for all engines. (no engine stated, so no exact answers)
is your gas or diesel (ill guess gas)?
gasoline and not LPG or other fuels. real gas ,nor flex fuels on E100
cranks but no starts.
blown fuses, check fuses first, ( always #1 with EFI)
bad gas.,
the first check is spark , gas dont burn lacking SPark (mr,otto cycle)
watch funny guy SCOTTY.

any engine can run on test fuel, if it has spark (Otto)
some engines will never start
  1. lost compreesion 1 or more cylinders
  2. melted CAT converter, blocking exhaust
  3. EgR stuck open, wide, if your unstated engine has one.
  4. fuel pressure zero or 10psi. dead. must be at spec.

4.3 vortec engines


If you done a tune up and the engine still is not running right. Before you go and replace alot of sensors and computers, pull the distributor out and check the drive gear on the bottom. if it worn even a little replace it. alittle wear will cause an engine to shake. i've worked on them were th engine was spittin and sputterin. the gear was chew about half way thru. replaced it and it purred like a kitten. to do the job you need to
1 pull the wires on one side of the cap and mark them
2 pull the cap
3 pay close attension to where the rotor button is pointing, mark the direction if possible
4 remove the 10 mm bolt that holds the distributor in place
5 pull the distrubutor up and out
6 check the gear. if there is no wear replace in reverse order
7 to remove the gear you need a punch pin, knock the shear pin out of the hole pull off gear and replace with new one. replace shear pin.
8 reassemble in reverse order.
good luck

Sluggish sputterin what can i do


I would start with replacing the fuel filter, they often are overlooked, also check the air filter. Try some Chevron Fuel Injector Cleaner. You might need a tune-up.

Hi i have a 2002 gmc sierra 5.3 liter engine i


Which o2 sensor did you replace? P0157 is low voltage - o2 sensor, Bank 2, sensor 2. So it would be the post cat o2 sensor on the passenger side. If you replaced the drivers side the code would still be there.

Gmc savana van will stop running while driving or start sputterin


It could be a clogged fuel filter or a bad fuel pump. Also try replacing the spark plugs and spark plug wires and having the timing checked. Good luck.
