temp fuel source to clear security

temp fuel source to clear security

Postby subwoof [OP] » February 28th 2014, 5:07pm

Hello!

First thread here so be nice in case this has been brought up before..:)

One quick question:

I have a 2000 astro van that has the security code on steady ( starts then dies ) and of course my 1998 and 2002 van's manuals aren't explicit enough / have the outdated info and without a scanner ( ordered ) I can only shade-tree diagnose.

Since the onboard computer(s) time out the fuel flow to the injectors to annoy owners ( I mean prevent theft of 10 year old gas guzzlers with rust ) within 2 seconds in security mode BUT the engine will set into it's "diagnostics complete, you can drive now" mode around the 5 second point, is it possible to substitute another fuel source ( propane, misted gas somehow ) to keep the engine running to that point?

Or does the computer never get to that decision point due to the previous "security" code??

The light never flashes so any learning attempt ( believe me I tried ) is useless. This was a fine running van until it went into security crapolla according to the previous ( equally frustrated ) owner.

Shots of starter fluid into the airbox should work fine if you still have spark.

Well there is spark since it does run for a whole 2-3 seconds, and longer if some gas is sloshing around in the intake....

As for computers, here's a pic of the *last* one that gave me fits...it also gave me a security code.

Ah yes the computer. From taking astronauts to space and back to allowing us to communicate via the internet. Incorporated into just about everything we use on a daily basis, making life worry free. Until the software gets the tiniest of glitches then your in for the frustaration of your life.
Maybe not the forum to post this, but this is what happens when you get a tiny glitch in the software. LG top load washer. I was sent here to diagnose the issue and take photos for a damage claim that was filed.
The thing spun uncontrolably in excess of the 1100 rpms it was designed to do. The suspension got ripped off the tub, put holes in the drywall from banging all over the place, flooded the room and the motor put swirl marks all over the wooden floor as it spun to a complete stop. It looked like a small explosive went off inside it. The only reason it stoppped spinning and possibly prevented the lady from being electrocted was because the wiring harness got ripped off the motor and the computer gave up an error code and cut the power to the motor.
So I guess in a way computers do there job???? :shrug:

As determined, but delayed due to multiple below zero days and snowstorms to confirm, the overall fault was that single melted wire from the ignition switch to the firewall connector C100....

That then went to the transmission - and back to the firewall and then to to the brake switch and then to to the ignition solenoid....jeez...2 garages in auburn NY, the previous owner and his so-called "mechanic helpers" couldn't find it and just gave up.

Well after replacing the so-called new battery ( one bad cell ), aforementioned melted pink wire, a number of hack-wired ignition / security bypass go-arounds ( somebody went online..:) it started on the VERY FIRST CRANK and just *PURRS*

The obvious dashboard idiot lights once again masked the true faults...maybe they should have a light that says DATA - this should of been another easier to deal with troubleshooting tree to diagnose the problem..time to update GM....

In hindsight the only reason AT ALL that the "security" light came on was because the individual "smart" components could not communicate on the data buss...period.
