I have a 1999 silevrado 5.3 the motor turns over but wont fire.. i was sparying mud off the undercarriage could have some got up accidentally and caused this.. if so what do i do??

mud across the terminals of the starter motor

clean the brake hubs

Hi, The only way the mud or water has got into the heads is if the engine or exhaust is stuck below the mud/water. Try to see if the exhaust is clear of mud or water if this is blocked then you will not start. But I think you may just have the starter motor has got mud into it, in which case you need to get vehicle pulled out & bump start it, IE: whilst either pulling or better to push the vehicle & get it to start. Do not turn it off until you have given vehicle a run as this will eliminate any mud around the flywheel which is why the starter will not work. Please leave me feed back: Malcolm Campbell, Thanks.

You are looking for SPLASH GUARDS... They sell them on-line

need to have it looked at sounds like the motor is knocking not what you want to here

ck wires go to starter make shur there is no broke wires or wires leaf off of starter

With number one being the cylinder at the very front,the firing order is,,1 5 3 6 2 4
If you look down on the top of the dist. cap,the shaft turns in a clockwise direction
The plug hole on the cap that is at the extreme outside i.e.the one furtherest from the motor,Should be number 1
Hope this helps

how much fuel, remember needs certain amout of preasure, also check injectors and injector pluse, if injectors are not turn on by computer it wont spray gas, try sparying starting fluid in throttle body see if it starts, start there now, good luck.
