95 Silverado hard start!

[gonzo694]

Ive been having a problem with my truck turning over on the first turn..Usually it turns over on the first try but now its been 3x's before it starts up. I was told after i had it in the shop that it may be your coolant sensor telling the computer its colder then it really is and thats why im not starting quickly.Can anyone please tell me where to find it and if its easy to replace? Thanks Gonz

Should be there by the thermostat housing. The wiring colors may be yellow and black.

As far as an extended crank, the first thing I think of is fuel pressure.

I have looked all over the internet trying to find where your coolant sensor is located but have had no luck. I don't know if this will help but on my 97 chevy the coolant temp sensor is located on the oppisite side of the engine (driver's side) from the thermostat.

Are you having problems with your truck running hot or the radiator fan not comming on?

I hope this at least points you in the right direction.

My first thought would be the fuel pressure regulator. It's simple to check. Perhaps some more info/details.
