THERE IS A NEUTRAL SAFETY SWITCH ON THE SHIFT LEVER, UNDER THE PLASTIC. THE PURPLE WIRE & OR THE YELLOW WIRE SHOULD HAVE POWER WHEN YOU TUN THE KEY TO START. THERE IS A ANTI THEFT MODULE BEHIND RIGHT SIDE OF DASH THAT MAY OR NOT BE A PROBLEM. THE TROUBLE MAY BE A BLOWN FUSIBLE LINK WIRE. THERE IS AT LEAST ONE AT THE STARTER, SOME AT THE POS. BATTERY TERM. SOME AT THE JUMP START JUNCTION. THESE THINGS ARE SHORT WIRES, THAT ACT AS FUSES. THEY ARE USUALLY THICK INSULATION, SMALL WIRE INSIDE. PULL ON THEM ONE AT A TIME IF THEY STRETCH OR COME APART THERE IS THE PROBLEM. REPAIR OR REPLACE AS NEEDED. I WOULD START WITH THE FUSIBLE LINK AT THE STARTER.

What does it do...anything? I assume you connected it properly the first time(i have to ask)

check vacum lines for leaks in the headlight assembly,sometimes they dry rot,the vacum lines] it has to a vacum issue. you may need to replace the vacum lines with new vacum hose. you can but it by the foot at any parts store, but you'll need to carry a peice of old one to get exact size.trace the vacum lines from headlights to the source of vacum canister,just to be sure that the canister itself isn't leaking. look for cracks in the vacum lines along the way.if you find that the canister is cracked,it can be repaired by jb weld and repainted,just to keep it original.thank you for choosing fixya.com

Yes Get the right key at a GM dealer, take along the car serial number because there are several chip options and they will have to look it up with serial number

These vehicles are common for leaking fuel injectors. I would do an injector drop or balance test.

About an hour, Open the lid where you put the fuel, there are four screws that you have to remove, remove the lid, pull the rubber boot out and there is the pump sending unit. remove the eight or ten bolts and pull the unit out. replace the pump and install in reverse order. These are the easiest ones I have done. You can do it.

check power to assembly- see if motor runs--if it does, gear must be rebuilt. parts thru Rodney **** follow instructions

simple fix if handy. kit available on line (google) paid 9.95. be careful take out whole headlight frame remove gear cover insert new parts. takes about 1 hr each.

check the fuel injectors - seems the new fuel is messing these up...

on the back of the throttle butterfly is a sensor that controls the amount of fuel and it has carbon paths inside it ands i think this is the one causing your problem ,

have you checked the EGR Valve for leakage? if it is leaking the valve will get very hot at idle right away after a cold start, also the intake manifold gaskets leak on these, it can leak under the manifold and on the top do a propane enrichment to see if engine smooths out at idle. I will bet the EGR or the intake gaskets are the problem, u also never mentioned the all important electronic engine control fault code test, go to the link for instructions on how to do this test without a scanner.
