On the way home from the meeting the fiero died.got it towed home.i was thinging it was the ignition module,changed it but it won't start.so i checked for any codes and got 13,32 and 44.so it looks like i have some parts to buy and work.all it does is crank over and over.

Have you checked the fuel pump relay?

13 and 44 are linked (Oxygen sensor out of range, and overly lean reading). 32 is interesting though, as that's the EGR fault code... As the one gentleman stated, we know it's a fuel issue. The most basic (But certainly not comprehensive) way to check the pump is to bang the gas tank with the handle of a hammer. From there, you can move on to: Electrical faults (Injectors/Pump/ECU), vacuum faults (Regulator) and mechanical faults (Injectors/Rail/Pump). As silly as it sounds... Do you have gas in the tank? |

Never shift into reverse without a back-up plan.

Yes there is gas in the tank 3/4 full.tryed to spray starter fluid and it would run but stop sraying and it dies.toke out the throttle position sensor and taped it cleaned the contakes and it tryed to start.the rail seam to fuel in it,the cap that is on the passanger side toke it off and pushed on the valve and fuel came out.so i'm thinking its the throttle postion sensor.lordco wonts $131 with discount for it and we found a new 1 on ebay for $25 with shipping but it'll take a week or so to get here.code 32 is egr and maybe a sticky throttle position sensor.we are going to change the egr my dad thinks it might be bad also why before this happened.oxygen sensor was changed when we bot the car.but with the car running a little rick it might be shot also.but if u have any ideas please let me know thanks.

Have you checked the TPS to see what it's reading throughout it's sweep? You should have about a 5V drop at full throttle, with it steadily decreasing from there. To be honest though, I severely doubt it would be a TPS. All it could do would be to over-fuel the system, not lean it out. If it was being over-fueled, adding starter fuel would further compound the issue, not correct as is your circumstance.

Your engine is starving for fuel. You seem to have pressure, so it seems to me that the injectors are not functioning properly.
There could be several reasons for this. Try the fuse box. Check to see if any are blown. The Dawg |

He already stated it runs on ether. That'd require spark. ;)
You said that you had fuel at the rail. Did you check it with an actual pressure gauge? You could have 10psi, but that wouldn't make it run. Full pressure (~45psi) will result in a jet about 3-4ft high if you hit the schraeder with a screwdriver for reference. |

As for checking the TPS, simply hook up a multimeter to the signal side of it an ground, with the key on (Engine doesn't need to be running) and move the throttle back and forth. Again though, doesn't seem like the TPS, to be honest. Clynt and John are correct in steering you towards fuel, the fact it runs on ether strongly supports that.

Yeah, ignore the TPS. It'd run (not well!!!!) with it unhooked.

My car is on its 3rd fuel pump. I have never had a GM car with an electric in-tank fuel pump last more than 10 years.
They're not that expensive as a part, but replacing involves dropping the (hopefully near empty) gas tanks down. It might be time for a new fuel pump. |

I don't mean to imply anything Ken, but do you regularly keep the tank near empty? Those pump require the gasoline for lubrication. If the tank falls below 1/4 tank, they lose that lubrication.

I was thinking how do this pumps work.do they work or not work,can the pump still work but not supply the proper amount of fuel.haven't dont the fuel filter but i'm thinking the fuel pump is not working 100% not supplying the full amount of fuel.can this happen?
