tried checking spark off the coil as well as straight off the plug - all good. Starting fluid, I’ve tried a small amount and larger amount…haven’t had any luck yet.

the weather hasn’t been cooperating lately.

 

battery - good
haven’t checked the alternator but didn’t have any issues previously. I’ve been keeping the battery charged during my troubleshooting hours.
coil - good
no mice and air box is clean but currently off during troubleshooting.

thx

 

this is my thought as well. To the point I started think it was something related the the AMS and/or PCM (some type of de-activation).

I need to check the new plugs soon. But previous (original) plugs did seem to be a little wet when removed but this was after trying a number of things including starting fluid.

 

If it cranks over, you have power to the starter, and you have spark, and the fuel pump is working, then you have soaked plugs and the fuel smell must be unbearable. Only thing that wouldn't work at this point is the timing. Fuel spark air, right? It worked for 38k perfectly as mine has for 280k. Something doesn't add up. I'd be throwing it to a mechanic. A good one.

 

had a little time to check a few things this evening.
*still have spark a random spark plugs.
*checked a few cylinders for compression (roughly 100-150psi)
*checked distributor for movement-no movement.
*checked grounds-seems good.
*visually examine some wiring -haven’t found any.
*still have 45-47psi on fuel rail.

the darn thing seems to want to start when cranking for a length of time and flooring the gas pedal.

besides not having luck with starting fluid, I’m wondering if could have recently filled the tank with crap fuel. If so, it’s never happened to me. Has anyone else had any no start issues after filling the tank?

btw-continuing to try to search the web for similar issues to mine. Yet, it seems they seem to fail to post they’re resolution

thanks in advance.

 

As discussed, these problems are usually a sensor, pcm, or other electrical issue, or fuel pump. Does it smell like diesel? Like I said, there must be tons of fuel in the cylinders either gas or other at this point, i.e. flooded. Take out the fuel relay and a couple spark plugs and crank it. Then try again and see if it sputters.

 

If it tries to fire with your foot on the floor, makes me wonder if the temp sensor for the PCM hasn't gone belly up. When it fails, the PCM thinks the engine is -40 degrees F, and positively DUMPS fuel into the cylinders..... Floods out right quick.

 

first off, sorry for my Delay in responding back to this forum and to the people that participated. Obviously, the truck has been sitting a bit. During this time the battery has been completely disconnected. And with the info from “HeyYou” regarding the temp sensor, I purchased and installed. With one cylinder plug removed the damn STARTED briefly. This actually caught me off guard and excited at the same time. I reinstalled the plug in normal everything up, and tried again. No start as usual. I pulled a random plug out quickly and noticed it did look somewhat fouled. I also used a cylinder camera and it did look a little wet. It’s kind of starting to look like with this recent start attempt after sitting for a while. And actually wanting to start but possibly quickly fouling. This could be the heart of the issue I’m having. It doesn’t look like it is the temperature sensor but I’m glad to have that replaced. So after this I elected to try a third crank sensor cause I don’t trust the quality. (Ohming out the original crank sensor and comparing to recent purchases, they don’t match). Still no luck!

question: can the 02 sensor, with no codes, be the one telling the PCM to dump fuel? Other thoughts?

 

thank you for your response. Please see me recent response/post. I did try the temp sensor, but after a number of tries it doesn’t seem to be my problem of no start.
