Merc 308 sprinter non starter

Spray some starter fluid into the throttle body. If it starts, you have a fuel system problem. Check fuses and relays and the fuel pump. If it still will not start you will need a scanner to read codes and look at the sensor readings.

NO CHECK ENGINE ON POSSIBLE FUEL PUMP OR CRANK SENSOR

Won't start how ? A crank - no start condition or a no crank - no start ? When you the the key an nothing happens , the starter doesn't engage an spin the engine - no crank - no start . When you turn the key an the starter engages an spins the engine but does not start an run - crank - no start . Now what is your doing ?

Had same problem with 6cyl. merc.
Started fine cold but wouldn't start when turned off hot.
Replaced spark plugs & worn dist. cap .Problem solved.

loose wire or corroded connection at the starter or alternator, if not that it cab be ignition switch too

Its probably your computer. Had the same thing happen to me about ten years back. About 500 dollars. better off finding one on ebay or at a junk yard.

could be damaged flywheel or bad starter remove starter and have it tested while starter is removed check flywheel

starter isnt engaging, if you know where the starter is, tap on it with a hammer
1 person crank it over while the other person taps on it - its on the back of the engine

If this is a gas engine, check the ignition coil or plug wires. A simple test...

Start the truck at night, then look under the hood while it's running. Don't use a flashlight or your headlights; it should be dark !

If you see sparks anywhere around the engine, you've found the problem. Now you can turn on a light to see where they're coming from - probably from a cracked ignition coil.

Good luck !
