No codes, fuel pressure is good when checked at mechanics shop. Like I said, it's an intermittent problem that won't present itself during inspection. I'm hoping that someone out there in internet world has come across this problem. It only happens when it's really hot and HUMID, I shut the truck off, come back and start the truck in 20 minutes and it won't start. The truck will eventually start right up if left to sit for about an hour. This issue has not happened to me since July/August of 2023. But this is a work truck and it leaves me stranded, which is no good.

I am having this starting problem with this truck. The problem ONLY HAPPENS when the weather is really hot and humid. The truck will run fine. I'll stop, turn the truck off, come back about 20 minutes later and try to start the truck. The truck will turn over and attempt to start but it'll stumble and stall. If I leave the truck sit for about an hour or so, come back, it'll start right up. The problem is that my mechanic can't do anything about it because the problem doesn't present itself while he's there. Has anyone ever had this happen to them and what was the cause of the problem? I recorded a video, it can be watched here.

I have a 1999 C3500 dually, crew cab, 7.4L gas engine. I am trying to locate the EVAP canister vent solenoid, anyone know where it is located?

Awesome pic! Thank you

I'm about to replace upper control arms on my 1 ton 2wd c3500 crew cab. Alldata manual says to tighten the upper control arm bolts to 140lbs with control arm at z height position? Im confused and don't really know anything on Z height position or if this even applies to my vehicle? Can I just lower truck and tighten the nuts down?

One other thing I noticed while the rear of the truck was in the air. When the truck was running and the rear in the air, the back passenger wheel was spinning much faster than the drivers side wheel. Does this mean the passenger wheel brake adjustment needs to be adjusted? Or is that adjustment star only for the parking brake?

Took the truck for inspection and their computer read out says I have no passenger rear brake. I had the truck up on jacks the other day and used brakes, wheels did stop turning. Also bled brakes because I replace a caliper and bleeding brakes at this wheel was fine too. What could this problem be?

I broke some type of vacuum line while flushing my radiator. Now Im trying to ID the line assembly so I can replace it. I have included a pic. The line had a 90 with a locking device built into the 90. The line was made of hard plastic. The line connects to a rail on the engine and a box near the radiator "where I put the white arrow". There is also a service port on the line with a green cap.

My C3500 starts fine in the morning. I drive the truck to a location and shut it off. When I come back to start the truck again, it's very hard to start, taking about 5-10 minutes of cranking the engine over to get it to start. It sounds like it wants to start at some points but it just fizzles out, then all of the sudden the truck just starts. For the rest of the day the truck doesn't give me any issues at all, the truck starts right up. I know this is an odd scenario but Does anyone know what this problem might be? The truck only gives me a starting issue on the second time it's started during the day.
