hey we got a 92 camaro RS, it was running fine untill we desited to drive it from san antonio to austin. itwas low on gas for quite awhile and we could start smelling gas in the car for a small amount of time untill we switched drivers then continued.. we finally get into san antonio and the car starts bogging realy realy bad and dies twice in trafic. we take it to the gas station and get a full tank, still bogging realy bad, we go to my house and turn it off and pop the hood to let the car cool down, we go out 2 hours later to crank it up it will not start, we tryed to flood the engin to see if the pump was working and we did not smell gas. Is the gas pump not working? what do you think the problem is? help

 

I could be wrong so someone correct me if I am, but running your car that low on gas could be bad cause it can pick up excess sediment from the bottom of your tank and clog your fuel filter, lines, or injectors

 

Do you have fuel pressure? How much?

I would have to say Zero

 

Is that a guess, or did you actually check it?

- Justin

 

ok, how do i actully get to my fule pump..i just found out that it is INSIDE my gas tank...

 

Undo your rear shocks, panhard bar, and sway bar endlinks, then lower the rear, and you're free to drop the tank.

Well out of the blue today we tryed to get it to start today and it did with the help of pushing the throtle down as well..though it sounded like **** we got it to run 3 houses down then it just died..my guess is it needs a new fule filter

 

Well got a new fule filter for it..Still wont run, We can get it to crank over with the belt rotating and all the nessisary things needed to get the car to start after maby 10 futle attempts. Then we will let it sit there and idel but it will Backfire continuisly and make alot of well not so healthy noises then eventualy dies after a few min. Maby its the fule lines?? Help

 

Go out, buy a fuel pressure gauge, attach it to the schrader valve on the fuel rail in the engine, and turn the ignition to the "on" position. do you have pressure?

if not, your fuel pump is shot. time for a new one.

 

Will being that low on gas really crap a fuel pump with the sediment? I've heard that before, but seems like if it's pumping from the bottom, it'd have the sediment anyway...

 

no, that wouldnt have much, if anything to do with it, it just may have been time for your fuel pump to go. check the pressure, then get back to us, and we can help you try to diagnose it.

 

Do you all think it could be that my timeing might be off. Thats what i hear is 1 major cause of blowback. Usilly it will do that alot right before it dies. But now its realy late so i cant do much to work on the car untill tommorow

 

So what was the fuel pressue?

 

Backfiring I thought was caused by cylinders firing out of order or not enough spark
