just had a guy call me to work on his jeep with same problem. when the jeep fails to start try holding the gas pedal to the floor. If this helps it might be the fuel injectors. leaking injectors flooding engine. easy fix.

 

I'll give that a shot. Thanks for the info!

 

You might verify you have the correct pressure. ^. Also, it should hold it. I think a 20 lb. drop in 1/2 hr is something to go by.

On my older renix Jeep, floored, cranking it's suppose to shut OFF fuel from the injectors if I have it right.

If your cold start problem is pressure being lost, (injectors, check valve, regulator ect.), cycling the key on for a few seconds, then off a few times should prime it and let is start as usual.

Since my injectors leak, if I do that warm I'll have a funky start then it will miss a second because I just flooded a cylinder or too.
