problems starting....
 

my 2001 has a hard time starting in the moring.... i have to crank it forever... it only seems to start after i press pump the gas? but its EFI??? anyone??

Leak in the system somewhere? Are you getting any codes? Iv had mine in some cold weather - 35, without plugging in started first try so, these trucks work good in cold.

Are you letting the fuel pump prime before you start?

RE: problems starting....
 

yes.. i am letting the fuel pump prime.. i even tried the , turn the key on let the fuel pump shut off.. then off.. then on again with no change...

Start with the basics......

How many miles are on the plugs?? When was the last time you cleaned the TB, IAC, TPS...etc...?

RE: problems starting....
 

Wait a solid 20 secs with the key in the on position. (Should hear the pump prime).
Then, try to start. If that's it, it's the fuel-pressure-regulator. That's my bet.

RE: problems starting....
 

If it is running fine after it starts, it wouldn't be the fuel pressure regulator.

Make sure the coolant temp sensor and air temp sensor are reading right.

Even though the on-off-on fuel pump bit didn't work, I'd check for bleed down with a gauge. 3.9, 4.7 and 5.9 should all be 50 PSI KOER and should hold at least 30 PSI for at least 5 minutes after shut off. Could also have a leaky injector flooding it; that should show up on the bleed down test.

could be a tps sensor. my truck was doing the same thing a while back. replaced the tps sensor and now its fine.

well since it's getting ridiculously cold out, at least where i live, it could be something as simple as a battery.. how old is it? take it to autozone and have them test it.
