Truck getting harder to start...wtf?

[Mr45]

I've noticed over the last few weeks, that it takes more and more cranking to get my truck started.

Anybody experience this before? Plugs?

 

[Modded]

Yeah that issue is almost always plugs, depending on mileage.

How old is the truck and how manny miles?

'01 90K miles.

I've put 15K miles on it, and never changed plugs.

fuel pump is on the way out sounds like....

(GM mechanic friend told me, when they get harder to start, look for fuel pump problems)

Don't go below a 1/4 tank to preserve fuel pump life.

I have this issue too sometimes....mostly though, while at the gas station, mine tries to start...turns over, then bogs out and dies...it does this once in a great while ...it takes about 2-3 times of starting for it to catch...very odd...


runs fine though...

it may be loosing line pressure sometimes.

Agreed, running fuel with low levels, heats up the fuel pump. Staying above a 1/4 tank, the fuel keeps the pump cooler, less change of overheat/failure.

Well...I'm going to change the plugs this weekend, and try to keep at least half a tank in there. Not a bad idea in hurricane season anyway...

Any recommendations on spark plugs?

So...went to fill up last night, and found my gas-cap very loose.

Filled up, tightened cap, and now she starts like she used to....

Could it be??? Low on fuel, gas cap loose, messing with the fuel pressure?
