Welcome to justanswer.
It sounds like you have a bad coolant temperature or connection to it.
the temperature is normal??
The temperature will be fine but the ecm doesn't think it is.
would that make the engine run real rich in fuel mixture ??
Yes and it will cause it not to start sometimes.
the plug,s are covered with soot too ??
Yeah it sounds like the coolant temp sensor i would also check the connector and make sure it is not broken or shorting out.
where do i find the coolant temp sensor ??
ok ill try that
It is located in the intake manifold near the water outlet to the radiator.
It has 2 wires if there is a bad connection it can cause this problem to. wiggle the connector and see if it changes anything.
