Need help, 94Q died in the plarking lot

[richardchen0530]

I went shopping today with my Q and screwed up the good mood for this weekend totally!When i started the car, idle fluctuated a bit(as usual), and i drove 1.5 hr perfectly. Then i parked the car, shut the engine. While i was walking to the mall, found a much closer spot, went back to the car to get my new spot, however, car would start, and stall and died. tried like almost 10 times, still dead. Had to call my friend to pick me up and borrowed his car to get home. Prepare to take my tool to the lot and change some parts there.What do u guys think might be the problem?Ohmed the injectors, one of them was bad. TPS plug seems lose. Fuel pump were new and no problem at all during driving, but the idle were never stable. Could it be the one injector?I think coils were good and plugs were new.Need helpthanks guys

Was the new fuel pump oem? Did you replace FPCU at the same time ?What is cranking fuel pressure? what is bleed down fuel pressure? what is time vs pressure graph.........leaky injector?

Wiggle that damn maf connector first

EDIT: I see its a 94, they dont have the same maf issues as the 90-93 do they dennis? (i may be wrong on that)

car was self protecting itself from dings and scratches caused by carless people that come from parking too close to any mall/store- the Q wanted to remain far from the idiots!

Wiggled the MAF plug, no useSeems like it's just around 200rpm after starts and then just dies

Pump were OEM, FPCU i didnt change but at that time, i didnt seem to have any problemI assume there might be a leaky injector but that shouldnt stall the car right?

Well, there is the potential for hydrolock, which would be a permanent stall.
