Warm Start Problems

[OR VietVet]

my thoughts exactly, who does that? unless you know the plugs are fresh and 1 happened to crop up with a problem.

At this rate, this vehicle has no chance.

Yeh I kinda thought you should just replace all them at once though they may be fresh my dad has had the vehicle for a lil.

Then, as the owner, you get to tell the tech what you want done and he/she can say, yes or no, and then you decide if you have them work on it at all.

and if one plug is bad there is usualy a reason why, bad injector, coil, something internal, etc.

Starting back at this thread. Replaced the one injector believed to be bad. Did not fix the issue. Took it to a specialist that does automotive electric and they’re unable to see enough live data in the few seconds it acts up to give me an answer and I can’t leave it.

My thought was maybe the computer thinks it’s losing rail pressure, when in fact it is not. This makes it think it needs more and floods it when starting.

Hail Mary, but does it act like this? (Vid taken about 20 minutes after getting home - still warm):

Pretty much. Sometimes it will catch on first crank and sputter and then run. Second crank always cranks right up.

Is it still on the factory camshaft position sensor or an aftermarket replacement? Mine did like in the video, or as you said sometimes catch, sputter, then run with an aftermarket CMP sensor. Put an OEM one back in and not a problem since. I drug my feet on swapping, even did a fuel pump and pressure regulator despite knowing aftermarket sensors are garbage in these. At least I've got new parts on the fuel system now. LOL.

I’m pretty sure it’s the factory sensor but I’m not sure. I’m not the original owner. Seems like a pita to change too.
