Fuel Pump Relay
99 Ford Explorer
Over the last 2 weeks my Ford Explorer has been cranking for approx. 2 seconds before it has fired up. I had the Fuel Pump replaced a couple of months ago because before the replacement i was having starting problems. Ford dealer replaced Fuel Pump and truck fired up right away after turning key.
But the last 2 weeks it has been cranking for about 2 seconds before it has fired up. I have read other post on here about maybe changing the Fuel Pump Relay.
I went to the dealer and bought a new relay and put it in. It has been about 2 hours now and I am getting ready to go somewhere and will see if it fires right up.
If it doesn't. Does anyone else have any ideas? My new Fuel Pump is only 2 months old. And the truck only has had starting problems after it has been sitting for more than 2 hours.
Does anyone think that the 2 second crank time isn't abnormal?

well nothing changed with me adding the new Fuel Pump Relay. Still took a couple of seconds to start. Not sure what the problem is. I was told when I very 1st start the truck that I should turn the key to the "On" position and let the truck go through it's systems check and then start after it does that. That way it will be able to prime the fuel pump. It should then start right up.
I don't think I should have to do all that just to start my truck. It should fire up right away like it did in the older days.
Does anyone else experience a long cranking time that they think is normal?

Nah, Lotic, you shouldn't need to go through all that monkey motion to start an Explorer. It should start right up.
Try cleaning the IAC pintle and the inside of the throttle body. Clean it where the throttle plate meets the housing side. Carbon build-up on those parts tends to degrade both the start-up time and idle quality.

I'm suspecting a leaky fuel injector, because as it sits for those two hours fuel is dripping into one cylinder. How has your gas mileage been?
One way to check it is to pull each spark plug after that rest period...is it wet with raw fuel? Of course one or two plugs are virtually impossible to get at, you could do the easier ones.

Had tune up done in which i changed out the spark plugs and the fuel filter a week before i had my Fuel Pump replaced. No problems were told to me at that time. Gas mileage seems to be the same as always since i have had the vehicle and the truck does not run rough or idle rough at all. Nice and smooth.
It's just that after it has been sitting a couple of hours it will crank over for a couple of seconds before firing up.
Now this morning when i started it it fired right up. That's from sitting from 8 pm until 6:30 am this morning. Fired right up and that's been the norm over the last 2 weeks.
It just seems when i go out to try to start it anytime after a few hours it has cranking issues, but if it sits for more than 10 hours or so, fires right up.

Well, finally took my truck back in to the Ford dealer to see if perhaps the New Fuel Pump that they replaced in September may be defective since it was still under warranty ( 12 months, 12,000 miles ).
Come to find out, it was my fuel pump again. The new one that they replaced in September gave way only after 3 months. They said it had a bad Check Valve in which after sitting ( my explorer ) the fuel was leaking back into tank therefore giving me the couple of seconds of cranking time to start.
Does that sound right? I could always here my Fuel Pump start when i turned the key to the on position, but when i turned to start it would take a few seconds.
Out of all the cars I have had, I have never had to replace a fuel pump. Don't Fuel Pumps last a rather long time?
I guess, I have 103,000 miles and it is 6 years old.
