93 S10 Blazer won't start w/out starting fluid/dies shortly after

HELLO, I AM NEW TO YOUR SITE, I HAVE READ SEVERAL POSTS W/SAME PROBLEM, BUT
I NEED FURTHER ASSISTANCE. I REPLACED THE COMPUTER BRAIN, THE FUEL PUMP AND
FILTER, REMOVED BOTH INJECTORS CLEANED REPLACED GASKETS/ORINGS, HAD THE
IGNITION MOD TESTED/PASSED TESTED THE PRESSURE TO FUEL PUMP, THAT IS
RIGHT, TESTED INJECTORS THATS OKAY. I'M AT THE END OF MY ROPE, HUSBAND
(15A MASTER TECH) HAS CHECKED EVERYTHING HE CAN THINK OF. ANYTHING ELSE WE
CAN CHECK? IT WILL STAY RUNNING IF THE GAS PEDAL IS DEPRESSED AS SOON AS I
LET UP IT DIES. HELP PLEASE, STUMPED IN ONTARIO THANKING YOU ALL IN
ADVANCE FOR YOUR HELP IN THIS MATTER

For starters, all capitals on usenet normally means you are SHOUTING at
someone. ;-)

I have seen those symptoms happen a fair number of times up here in the
rust belt when the ground strap to the body fails. The vehicle then
steals the ground and the gas pedal cable is a common theft route with
the radio being second.

On GM's the mesh ground strap usually runs from the bell housing to the
body and it just up and rots because it is open to the elements.

To test this, I run a booster cable from the battery negative to a metal
point (I scrape paint if needed to get to the metal) on the firewall or
fender and see if the symptoms change.

Hope this helps,

Mike

Check the temp sensor this can cause a rich mixture and it will not idle,
also egr may not be seating, excess fuel pressure or an injector stuck wide
open all possibilities to check out. Severe vacuum leak at the throttle body
base, inop idle control motor also

I think Shep has the idea...it sounds like the EGR valve is leaking or
the MAP sensor is leaking vacuum to the EGR at idle.

A quick test, disconnect and plug the vacuum side of the MAP sensor to
the EGR valve.
If engine idles and doesn't stall, MAP may be bad, if it stalls EGR may
need cleaning or replaced.

If things don't change, then it may be a problem with the IAC.
