Hard Start After Hot

[Big T]

Hard to restart engine ('99 K2500) after shutting down after a full temp run. Clear return line at IP shows large bubble. What do I do next?

 

[Will L.]

you are sucking air possibility. Is bubble stationary or is it a small trail of bubbles

 

[Will L.]

Have you tried pouring the water over ip to see if it starts?

 

[Big T]

Have you tried pouring the water over ip to see if it starts?

No. It’s a brand new IP. Not getting fuel.

 

[Jaryd]

I would at least try pouring water on the ip. Just to see what happens.

 

[Big T]

It sat for one half of football game and would not start just before half time. Waited until game was over and it started right up.

It just did not want to be bothered during the game. LOL

Well my team was playing like a dog, so I wanted to go fill it up at half time. Too late now, gone to NY for two weeks so I put it in the backyard.

I guess that`ll give it plenty of time for a cool down. LOL
Have fun while You are there.

If Will L is saying my IP is bad, then I’m blame the curse on this board. My work travel really screws me. Then I have surgery to repair a completely torn peroneas brevus tendon in my right ankle on 11/22. I will be on crutches or a scooter for awhile. Rehab for 6 months. I’m screwed.

New does NOT mean good. Your description sure sounds like a bad rotor head to me. Won't start after a short sit, but starts right up after it sits longer. Try the water next time.

So tell me, what the heck will pouring water on the IP prove?

 

[Will L.]

The ip gets hot from engine heat. That expands the outside body of the pump by a few thousandths. The added clearance will not have an effect IF it isn’t to worn away. Think of piston rings in a cylinder. As it wears material from both surfaces go away.

The cold water causes the aluminum body to restrict and allows the pump part of the IP to work.

Rebuilding an ip but an old head and rotor is something rebuilders get away with 85% of the time. They are the most expensive parts of the IP so people try to get a good deal or better price, and thats what they end up with. Most of the time it works out, not all the time.

If you can recreate the problem and pour on a gallon of cold water without it helping, then you may have a different issue, but it is going to take hours of diagnostics to figure it out usually. Starting with have to know fuel pressure before and after filter.

Be praying for a complete and speedy recovery for You.

It’s not life threatening. Injury is 18 years old. It has just slowed me down quite a bit lately. I’ll be fine, but thanks.

Where did you get the pump from

 

[Big T]

Where did you get the pump from

Conestoga diesel.

 

[Jaryd]

When you get home take it for a good drive. Get everything up to operating temp for a while and shut it down and do the cold water test. If it does it again, I would call conestoga diesel and get them to make it right.

There is another member on here that ordered a ip just a couple weeks ago and not long after he put it on his truck it started showing signs of a problem. He had to buy the second ip and send the bad one back. Once they looked at it and decided it was a bad ip, they refunded the money for the second ip.

I’ll do this today in the AM. Warming up with a cup of coffee. Then i’ll go fill it up and drive it up and over and back over Hacienda Heights. That should warm it up.

 

[Big T]

Filled the truck up and drove it around until full operating temp. Shut it down and did some packing for my trip. Came out to start and it started right up. So couldn't replicate yesterday. Probably needed to drive it harder and further.

That slow initial turnover to the starter has me thinking I need a PowerMaster.
