Screwd up 6

Before anyone asks...I have googled the shat out of this and have found TONS of things that people claim it could be from a dryrotted hose on the fuel pump inside the gas tank to the auto shutdown relay. My problem is the jeep use to turn over in about 2 seconds....now it takes about 5 seconds and sometimes will choke up and stall out the first time it fully turns over. The next time I turn the key it starts up immediatly.

I noticed this problem after I changed my oil. I dont know how much that could related, but the engine has 104,000 miles on it. I put 10w-30 in it which i know isnt a super thick oil. Could me doing this and removing old thick oil cause the longer cranking times?

Any help would greatly appreciated.

Do you have access to a fuel pressure gauge?

what if you try turning the key to the run position for a few seconds to let the fuel pump prime/build up pressure, then try starting it?

when was the last time it had a tune up start with the basics u might be surprised just plugs can cause a long crank or hard start

Tried this already and got the same results.

New plugs, wires, cap, and all was done about a month ago. I did all that right away when I noticed the longer starts.

When you turn the key to the on position, can you hear the fuel pump kick on?

i have never heard it kick on...even when i first got the jeep.

Mine used to do that, my battery terminals were corroded and it would barely start and when it did it would idle realll low and shut off

I've never been in a pre-'97 jeep that I couldn't hear the fuel pump on.

That's just my own personal experience mind you, but if it were mine, I'd swap the fuel pump (and fuel filter too, just because).

I have already changed the fuel filter 2 times. if i sit in it and turn the key to on and wait 5 secs....then do it again 3 more times it doesnt start any faster.

Terminals are clean and has brand new optima red top

I recant that.

First, I'd pull the battery and have autozone test it for me. They generally test them for free.

Remember, heat kills batteries and even in perfect conditions, they don't last forever.

If the battery is good, but dead, check the alternator (IIRC, autozone can check those as well!).

Always rule out the easy-to-fix causes before you start wrenching.

If it's drivable, they have a cart they can wheel out to your rig to do the testing.
