| 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? |

No i haven't i can hear the pump working.where is it located? |

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. ------------- Never shift into reverse without a back-up plan. |

| How do u check the TPS for the reading.when we try the starter fuild it wonts to run but when u stop with the starter fuild it just cranks over. |

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 ------------- You dream it up....I'll make it |

| All the fuses are good.when we left the meeting it ran fine then the check engine light came on and it started to lose power and died.it just cranks over know. |

| Do you have spark?? |
Posted By: Dr.Fiero

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. |

| The fuel filter is 5 months old but it could be plugged.I'll check the jet we don't have a fuel pressure gauge.let u know tommorrow thanks. |

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. ------------- Never shift into reverse without a back-up plan. |

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

| We tryed the valve today with out cranking it just a little came out.we also tryed cranking it and very little came out.so no fuel in the lines i'll get a new fuel filter and change it out and hope thats the problem let u know if it works. |

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. -------------  Beken (aka Ken) - bekentech@westcoastfieros.com Original and still the owner of an 85SE 2M6 4spd |

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. ------------- Never shift into reverse without a back-up plan. |

| 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? |

| explain lubrication?i can see fuel as a heat sink but no more... |

| i would think that pumps can get week ...i would check for pressure at filter .. and then pull tank if there is little .. |

It could if there were excessive resistance in it's power supply, but that'd be a "real treat" to check. Other reason you could have pathetic pressure include:
As you said, the pump not being "fed" proper power can also cause insufficient fuel supply.
And Clynt, I assume Chevy does the same as Ford (Because everyone wants to be like Ford), but with Fords, the moving parts of the pump (The part that actually pumps the fuel) have nothing in between the metal. They rely upon there being a sufficient quantity of gas (In Ford's case, 1/4 tank) to be present to keep things lubricated, not unlike what the oil in your engine would do. ------------- Never shift into reverse without a back-up plan. |

Actually, it's not that hard to check what the pump is pulling. I even have a gadget for that (no surprise?!). I can even see if one segment of the motor is out by watching the current pulls on my scope. And the fuel acts as a lube AND a coolant on these (the fuel is drawn directly across the internal parts of the motor!). Running out of fuel is the best way to kill them. Running low doesn't really matter since it's internally cooled by the fuel. That aside..... I think it was already asked, but... do you hear the pump turn on for a little over a second when the key is first turned on? You can force the pump on by yanking the cover off your fuel pump relay, and pushing the relays lever down (or just pull the relay and jumper the power to FP pins). That also eliminates the relay itself as a suspect (ask John John if the relays ever fail! He croaked on the side of the road a couple of times from it). |

No...I never run my tank to empty. I always fill to full and run to 1/4 then look for a gas station. Usually it is at or below 1/4 when I fill my tank. I had a friend with a Corvette who NEVER let his tank get below 1/2 and his fuel pump still went. ------------- Beken (aka Ken) - bekentech@westcoastfieros.com Original and still the owner of an 85SE 2M6 4spd |

Not that it matters anymore with this problem, but there is another possible reason for a poor fuel supply. My 84 Duke would start, run for a couple of seconds then die, so I checked the fuel pressure. At 4 psi it was well below the spec of 11 psi. The problem was not the fuel filter. After dropping the fuel tank and I noted that the short rubber sleeve immediately on the discharge of the fuel pump (inside the tank) was quite spongey, so I replaced it, and installed hose clamps. It would have eventually failed, but it failed at that moment because the hose had softened sufficiently that it lost its grip on both the fuel pump and the metal pipe. I installed hose clamps because somebody on Pennock's suggested doing that. Now 11 psi. Gary
