Mustang Flooding Itself
[>:]I have a 93 coupe with a 306 trick flow heads, trick flow stage 1 cam, 30 pound injectors with a pro m, performer intake, 70mm throttle body.. And for some reason this car will start perfect in the morning first thing i can drive it no problem but if shut it of once it has reached running temp it doesnt like to start... i can sometimes get it to start by holding the gas pedal down before i turn the key but i do it wrong thats it, it wont start.. How can i fix this.. i really want to start driving the car but its not reliable.. ive been at this for 2 month now and yesterday when it wouldnt start i unplugged all the injectors and it started up..

RE: Mustang Flooding Itself
whats your FP set at? does the car have a chip in it? Iwas running 42 without any problems with a stock EEC. have you checked for codes? maybe the temp sensor isout of range.

RE: Mustang Flooding Itself
ok guys these are the things ive done so far.. checked fuel pressure good 39 and it holds pressure when off, changed the relay under the hood for the fuel pump, changed ignition switch, tried 3 comp 2 A9L and 1 A3M same result, does it with 24 and now 30 pound injectors, by the way stock comp no chip. pulled the complete harness out looks brand new the car only has 61000 original miles the one thing i did was convert it from auto to stick, car has mean spark tried with and without msd, tried it and the coil cap and at each plug, put new wires and cap by the way. ive done a whole check list for this car with a volt meter checking voltages everything seems to be fine.. someone please help this is driving me crazy and i really dont want to go carb.[>:]

DIY KOEO/KOER/Cylinder Balance Self-Test ....also suggest to monitor fuel pressure after engine is shutdown at op temp, check its leak down rate + check if there are signs of fuel in the FPR vacuum hose.

RE: Mustang Flooding Itself
can you get your hands on another mass air to try? and did you check the Temp. sensor to see if the resistance is right? not volts Ohms. then I would start checking grounds. also have you checked it for any codes.
