Need some help.... The other day, I filled up my gas tank, and on my way home I decided to get on it a little. So I hit the throttle and the car lost all the power, but didn't stall. The check engine light never even came on. I let off the gas and the power came back until I punched It again. So I took it easy the rest of the way home, and it ran fine, as long as I drove normal. The next day I went to start it to go to work, and it would turn over fine, but won't fire up. I have checked for spark thats fine, I changed the fuel filter, and the pump is running fine. It also has a brand new battery in it. I also put some octane boost into the tank, thinking maybe I got some bad gas. I pulled the codes and get 111 the 10, witch is nothing. All my fuses are good also. I do not have a fuel pressure gauge, so I haven't checked that yet I think it should be 35-40 psi. I know I'm getting fuel to the rails. I think it may be the TPS or the crank shaft sensor?? Is ther a way I can test those, or will I be wasting my time...Please help me.

By the way I have a stock 95 GT with 70,000 miles on the clock. The only thing I have done to it is a K&N filter, Flowmaster exhaust, no chips or major mods.

If you're getting spark, I don't think it's the crank shaft sensor. Sounds more like you're not getting fuel. If the fuel is getting to the rail OK and the pressure is OK, the injectors would be suspect. You can get a noid set to check and see if they are getting power as they should. Other problem that could cause something like this is a huge vacuum leak. If you press the gas pedal down some but not to the floor, does it start or try to start? Note: if you floor the pedal the computer will interpret that as a flooded condition and will shut the injectors down.

i tried variuos positions with the gas pedal, with no luck. is a "noid set" a common tool? i haven't heard of this... i was checking out some other forums and so people think it may be the pick up coil also known as the stator?

its just a little light



and heres the set

check and see if you have the proper fuel pres.sound like the pump has gone south

Again, if you have proper spark, it's not the stator or the TFI (Thick Film Ignition Module). Think from the basics. An engine needs 5 things to run. Fuel, Air, Spark, Timing, and Compression. Your description did not give any indication of a compression problem, it's very unlikely that your timing suddenly jumped that bad with 70K on the odometer (but not impossible), you stated earlier that you had spark, so that leaves fuel and air. As I stated earlier, unless you have a huge vacuum leak, air is probably not the issue, and your further diagnosis of trying multiple throttle positions takes air pretty much out of the picture, so that leaves fuel. Check your fuel pressure. If it's ok, that leads to the injectors or the system controlling the injectors (that's where the noid lights come into play).

today i'm going to get a pressure gauge to make sure i have enough pressure at the rails...if i don't then i will replace the fuel pump. i will keep everone posted.

got the gauge....its right around 35 psi, i have spark, and i cleaned the MAF sensor. I'm going to try to test the injectors with the noid light, as soon as i find one. if any one has any other ideas let me know....thanks!!
