I have a 1992 Sc300, today driving to work, my car acted funny it dies, it won't start again, so I thought it was no gas (since I didn't have much of gas anyways),

walked to gas station, got 1 gallon of gas and came back to my car, put it in, started right up perfect and idel fine.

after 5 mins, it dies on me again, no check engine light on,

waited around 20 mins, it starts but dies after 1 min or so...

what could be my problem with my baby???? fuel pump??? ECU??? fuel pump computer???

oh, by the way, used fuel pump and fuel pump controller was replaced around a year agon... did not drive this car for 8 months or so...

tried to pull check engine light code, no success, the engine light and o/d light blink every 0.5 sec forever....

Thank you in advance,

Doug

check the connections to your battery terminals...

It's going to be a bad battery or a bad FP ecu. When your battery is dieing, it will cause the car to die randomly, and the FP ecu will cause the car to die after warming up for about 10 minutes, search "12v mod", do it and see if it works before buying a new battery.

I am so pissed now... changed fuel pump ecu, no luck,

changed fuel pump, still no luck...

is there any mechanic live around downey area??

It is not TPS sensor either... I went to autozone and they actually let me purchase it and return it if it is not TPS...

um.... so maybe some more details? lol. I'm having a similar issue- he hit the black plastic part of the maf? Kinda confused as to what was actually done here

miraluna

iTrader: (2)

yes, pretty much... every time he hit on the plastic part, it worked fine... that's how he figured it out... and then, he replaced with the one that I have laying around... funny... oh, make sure you disconnect battery b4 replacing maf, which I didn't do... I think that made a difference... and look for a vaccumm lose...

my next move was going to be IAC... and to iginiter... and ignition coil... hehehe... I am thinking of getting all of them as spare parts for later... if my car acts up again, I am going to replace all of them... hehehe...
