So I recently have done my timing belt at a local shop. Car started fine when I picked up my rig. Started fine the morning after I picked it up. Did an oil change and washed my car. Still no problems starting. I go to work (30 miles) but when I am ready to leave my rig won’t start. I try jumping it to rule out the battery. No luck. It seems to crank but it is not turning. I pop the hood and notice this nipple/hose broken off. Does it have anything to do with my problem?

 

That’s a vacuum valve for your power steering system. It’s most likely causing a vacuum leak. I wouldn’t think that small of a vacuum leak would throw your fuel trims off enough to cause a “no start” issue.

Can you feather the throttle while it’s starting and keep it running by continuing to feather the gas pedal?

if it’s a fuel trim issue... it should correct the fuel demand enough to keep it running..... if you can keep it running by feathering the pedal.


But you need that airline fixed. They aren’t expensive.

But I also think you’ve got a bigger issue... check to see if the Argentine hose is connected on the air intake tube and the pass side valve cover. The shop may not have gotten it connected securely.
They most likely broke that valve and tried to glue back it back together also. It’s easy to damage when doing the timing belt.


but the vehicle sounds like it wants to run... it’s just got to big of a vacuum leak.


Or it could all be a coincidence and you got bad fuel after the work was performed. The valve could also have just come apart with age... and have been that way for a while.

But id be looking at the intake tube connections and where they go.

 

I agree - sounds like a vacuum leak. And I'm also surprised that such a small hose could cause this.

But my last experience with a no-start caused by a leak was on a 1981 Mercury... (Jiffy Lube left the crankcase breather hose off the air cleaner housing)

I’d be willing to bet that isn’t the only hose disconnected or broken.

 

Thanks for all the responses! I ended up taking it back to the shop where I had my timing belt and service done (Lextech in Highland Park, Ca) it ended up being my cam sensor. Apparently my wires were frail. They replaced it free of charge and also fixed the broken part in the video. Back on the road and ready for the trails!

 

This happens a lot. The wires for the cam sensor arent routed correctly when everything is put back together after changing the timing belt. The wires are rubbed by belt and eventually short out.

 

Frail my butt... they were not routed correctly as mentioned above and finially wore through.

 

I didnt even think about that... makes perfect sense. The way the 4.7 wires come between the belt is jus a crazy design.
I can see how a shop could screw that up. Although a good tech should have taken note when disassembling tge timing cover.

Id be pissed.
