car shuts off while driving!
car shuts off while driving! ok my fuel pump took it ****.so i decided to go with the WHOLE racetronix setup.the car ran fine for week.then while i was diving it just dropped in RPM and the car bogged out.and the "CHECK GAGES" light also came on.then after about 30sec it fired right up.but keep on doing same thing.
things i did to try solving this issue: redid all my grounds,clean the whole throttle-body including tps,maf,etc..car still doing the same thing.also once a while the coolant light comes on but i checked all fluids are good.also i checked the oms and voltage on the injectors.oms are right around 12.9-13.0.and voltage id around 10.it has stock injectors.
according to the last owner the car has mild cam, headers,borla exhaust,heads were redone,and the car is dyno tuned.i did everything but nothing seem to work.someone please save my car before i sell it.

Check the 4 prong pin on top of the fuel bucket. I chase this issue befor. The prong for the power to the pump would seperate when it got hot. Once it cooled it bonded back together. Its kinda rare but it happens. The lilbitty prong is not desighn to carry that much amperage for the walbro. Its funny because i only happen to me once. Also check the fuel pump relay and fuse. The relay can get stuck if its oem.
thanks for the input.so i have bypass the racetronix harness?and relay for the pump is located under the hood right?not the racetronix one right?
"and voltage id around 10.".... Something not right, there.
A data log and a fuel psi gauge on the windshield would be a big step towards finding the problem.....................

this was my next step.but funny thing is that it wont do it for day or two then out of no where it does that.and one thing i did today was remove the fuel pump relay while the car was running and it did same.bogged out and check gages light came on.i did put new relay while back.but going to buy new one tomorrow and c wht happens

no codes?
regardless you might wanna know what code/codes it has.
might wanna read the tps see where its at or what its doing.
also IAC as well.
i had a tps sensor code come and go. spring was sticking.
play with the tps and reset it a few times just played with it and the apparently unhung its self.
so far no more drop in the idle like yours is doing. plus i am running a stock air box and car is starving for air according to the IAC readings.
just a thought
good luck

Crank sensor wiring or connection. We brunt ours up on the dyno, car made one pull then died no start,no codes. Went as far to swap pcm's then found the wiring brunt. Repaired and the problem went away.
Let us know what you find.
Are you sure about all your grounds. I had one come and go on my MSD window switch. Sometimes it would work sometimes not.

im having the same issue. new racetronix pump, new ICM, New Opti, and new ignition coil. im going to try and get a new fuel pressure regulator.
my fuel pressure doesnt drop like urs does.
can the fuel pressure not drop and the FPS be the issue?

if u follow the racetronix instructions they make you delete the regulator thats in the tank.and i dont know how to replace the one on the rails.could be diffrent on the lt motors.not sure.but im really confused.lol
i would check to make sure you are getting a return from the return side or didnt kink a line at the sending unit inlet.
venturi could have popped off or be kinked or not even hooked up or not supplying enough fuel back into the bucket.
make sure your straw from the pump to the bottom side of the module/sending unit is a good seal.
i have installed several of the racetronix pumps and have not had one issue.
i installed a walbro on mine and i had to replace the rubber hose that goes from the pump to bottom side of the module/sending unit and use efi hose clamps,they are tapered on the inside.
good luck

so i decided to take out the racetronix harness(probably cheap china made **** ) and hooked it up to the factory harness and she is back.no shutting off no more.wont be pushing big hp for while so i guess it will be fine.thanks everyone for you help.i really appreciate it.
