RangeStang Posted February 5, 2008 Report Share Posted February 5, 2008 So I have a starting issue every once in a while. I think it is a fuel pump just every now and then when you start the car (92 lumina) it will immediately die if it does not do that it will run extremely rough until you snap the throttle in gear. I checked the fuel pressure and at idle it runs 32psi it is supposed to run 34psi and it runs 40psi at WOT. When you let off the gas from WOT it drops down to 30psi then back up to 32psi It has a new fuel filter BTW. Do you guys think it is a pump or a FPR. Please let me know ASAP because I have to go to Kansas city on Saturday witch is a 5 1/2 hour trip one way for me I just need to know if it will make it their.

93CutlassSupreme Posted February 5, 2008 Report Share Posted February 5, 2008 Is their fuel in the vacuum line running from the FPR? If so, it's bad. Quote Link to comment Share on other sites More sharing options...
BXX Posted February 5, 2008 Report Share Posted February 5, 2008 Is their fuel in the vacuum line running from the FPR? If so, it's bad. No, its seems to be regulating fine. Change the fuel filter again (it coulda gotten clogged by shit in the fuel tank), if the problem isnt solved, it's safe to say the fuel pump is about to fail. I wouldnt drive anywhere until the problem is fixed because you will prolly end up stranded. Quote Link to comment Share on other sites More sharing options...

Man that is not what I wanted to hear thanks guys. Hey what is the module or what ever that controls the shifting called? I think it is bad also how do I check again sorry kind of lazy today I know it has been talked about before on here. Quote Link to comment Share on other sites More sharing options...
19Cutlass94 Posted February 5, 2008 Report Share Posted February 5, 2008 FPR's dont really go bad that often on these motors. Im willing to bet its the fuel pump. They are more of an issue than the FPR's are. Quote Link to comment Share on other sites More sharing options...

They are more of an issue than the FPR's are. I mean it only does it every once in a while but I just don't want it to leave me stranded in KC. P.S. it's also got the famous GM pump whine.

Yups, its gone bad, only a matter of time until it has complete failure. Quote Link to comment Share on other sites More sharing options...
RangeStang Posted February 5, 2008 Author Report Share Posted February 5, 2008 Yeah It's been like that for 6-8 months now. No one answered my question about the module that controls the trans is called. Could someone also tell me how to tell if it is bad.Thanks Quote Link to comment Share on other sites More sharing options...

Could someone also tell me how to tell if it is bad.Thanks Module??? It's not a dodge product. The trans has a few pressure switches, gear selector switch, vacuum modulator, TCC solenoid, and the associated wiring to the ECM... Quote Link to comment Share on other sites More sharing options...
RangeStang Posted February 5, 2008 Author Report Share Posted February 5, 2008 I know,vacuum modulator that is what I was talking about it down shifts hard and has slow shifts up just cruising. I have already tried to adjust the d-tent cable it helped a little but did not fix it. How do you tell if the vacuum modulator is bad?

If a new one doesnt fix it, well then you know you have a new part. Hard downshifts and SLOW upshifts is typically a trans fluid issue, or the trans is failing.

RangeStang Posted February 6, 2008 Author Report Share Posted February 6, 2008 is it hard to start when hot? or even or only when cold? It's not hard to start. Just in the morning when it has been sitting all night you will start it and it either starts and dies right away or starts and idles relly rough and tries to die. But like I said it only does this about once or twice a week. It's just hard to track something like that I've hooked a scanner to it and tried to pull the codes and nothing.

Mr_Efficiency Posted February 8, 2008 Report Share Posted February 8, 2008 The hard starting and rough idling sounds like the IAC, mine did that. as soon as you get moving its fine, right? I just pulled out the IAC and it was a little stiff and sticky. I just cleaned it up and poped it back in and had no probelms since. Quote Link to comment Share on other sites More sharing options...
ns87 Posted February 9, 2008 Report Share Posted February 9, 2008 Check that little vacuum elbow on the front of the modulator. I've had that crack on me, as well as 2 fail. If its bad, you'll know by a HORRIBLE 3-2 downshift Quote Link to comment Share on other sites More sharing options...
ns87 Posted February 9, 2008 Report Share Posted February 9, 2008 and for the fuel pump... Do you take off and the car stutters? Do you have to keep your foot on the gas when you start sometimes? Does it sound like these?.... Ignore what I said about the smoke, I'm an idiot . But that was my dying fuel pump Quote Link to comment Share on other sites More sharing options...
rockfangd Posted February 9, 2008 Report Share Posted February 9, 2008 its a long shot but check the fuel pump relay. mine has gone bad 3 times within 4 years and when it goes i know it because it is hard to start until it gets signal from the oil pressure sending unit. cheap and possible. i would start there Quote Link to comment Share on other sites More sharing options...

But that was my dying fuel pump Sorry I have not posted on this topic lately my computer died on me. But anyways my car sounds like the second video but the only difference is that it will die like three times and then start. No I don't have to press the gas down to get it to start. Thanks guys Quote Link to comment Share on other sites More sharing options...
