![]() Last night I had to get towed home - 44 miles - $215!! Well, my car ('89 GT) will start and run for a few minutes then bogs and stalls. I'm about 90% sure it's my fuel pump. I think the initial start up gives the car enough gas to run for a few minutes then the pump craps out. What do you guys think? Another reason I think it's the pump is that when I first turn the key, I don't hear the pump as loud as it used to be. Any ideas? If you guys think it's the pump, what do you recommend for a replacement? My car is basically stock but I do have some future mods in mind. Nothing to radical as it's my daily driver. Thanks for any input or advice.

![]() Sounds like the fuel pump or very very clogged fuel filter. You said that you are going to do some little mods to the car so I would get a 155 or 190 gph pump depending on what you are going to do.
------------------ 91 LX COUPE, 3.73 gears, 2 1/2 inch full exhaust, 1 5/8 shorty headers, 73 MM C&L MAF, 70 MM MAC TB, LUNATI cam, Windsor jr heads, GT 40 intake with ported lower, world class T5 with PRO 5.0 shifter, Griffin aluminum radiator, Fluid Damper, SSM traction bars, 150 HP shot N2O kit, 190 GPH in tank fuel pump with Paxton T-Rex external pump. And more to come. BEST TIME ON BOTTLE---11.51 @123 BEST TIME ON MOTOR---12.63 @109 |

![]() Thanks for the quick reply 5oh. I changed my fuel filter about 2 months ago while doing a tune up. Yeah, I was thinking the 155.

![]() Probably wouldn't hurt to check the filter again, it might of had some crap go through it. I think at least a 190lph pump would be in order, and when you remove your old pump, inspect the inside of the tank to make sure there is no crap floating around that could clog your filter or pump pickup.
Good luck!! ------------------ B.R. L.X. 5.0 coupe Cruise control,power mirrors,...and Thats it! ( except for the supercharger ) |

On the note of whats wrong, your fuel pump is burned out. Your pump is overheating and then shutting off. When you wait a few minutes, it'll run again for a few seconds, then overheat. It'll run longer at first startup because of that. The altered sound of the pump is also a very common occurance. |

![]() But U never stop modding though. I say go for the 255 cos it will work fine with your stock setup and will accomodate many many more mods. It WILL NOT make U run any richer than usual
Also remember technically 155lph will support 400FW HP which equats to ~340RWHP. BUT under WOT the electrical system is taxed and U do not see 155lph. Actually U will see more like 110lph unless U add the electronic boost a pump. ------------------ Black SN95 TFS heads, Holley intake, AFM B-2 cam, 12.9 @110mph best ET 13.06 @111mph best MPH After gutting out clogged cats and a much better tune.
