3rd Gen Dying Issue... Stumped

Make sure your intake tube has no air leaks between the MAF sensor and the throttle body.

Do you have a scanner?

When was the last time you ran a good quality injector cleaner through it?

I replaced the entire intake already just to be safe, no change.

I ran an 2 bottles of sea foam and one bottle of injector cleaner through already too. No change.

No codes come up on my obd wifi scanner.

Also check the EVAP canister.

I've decided to not waste anymore time or money on the truck and am just going to sell it, since need to have a more reliable driver. I'm guessing the issue is with the immobilizer since the security light starts flashing after the truck dies. Then the ignition must be switched to"off", then back to start to start it. But when you turn the trucks off manually, the light stays off and can be restarted without turning the ignition to the off position. But who know, could be fuel pump, or evap canister, or a number of other problems.

I'll post it to the sell section and craigslist tomorrow after i wash it and take some pics.

Thanks for the help.

The alarm system is factory?

If it is do all your door switches work?

remove the security system from the equation, there should be all the factory plugs in ur wiring harness so u just have to back track the wiring from said and plug and play to remove the unit. With that said my understanding is the system cuts pwr to the starter and NOT the fuel pump so dont think its ur issue, but may inquires into issues with security r limited so I could be wrg.

To clarify, it does not have the factory alarm system or aftermarket alarm system. It only has the factory installed immobilizer that came in the 99+. There is no way to bypass or unplug it.

It does not have an alarm system, only the factory installed immobilizer that came in 99+. Everything else works exactly as it should, I sliding the switches.

I have a 2000 and u can absolutely bypass it and its really very easy, (the rs3200 control box) the smallest plug with 3 wires (grn, grn/blk) unplug it and use a jumper wire on the plug it's self (not the box) and it will start right up...

Although I appreciate your help, it does not have the rs3200 alarm system or any alarm system. It only has the immobilizer where you insert the key (technically located on the ignition cylinder to read chipped keys), which I believe is wired indirectly to the ECM. This is absolutely not the same as the alarm system, I assure you. With the immobilizer unplugged, the truck will not start, same as using a non chipped key.
