car turns over but won't start, help me please!

so i'm driving this morning and i stop at a stop light and my car stalls, this is the first time it ever stalled (auto) while i am driving it. yesterday it wouldn't start at first but then it started an hour later but i didnt drive it around. when i turn the ignition the engine cranks but no fuel is going into the throttle body. at first i though it was the fuel line/filter being plugged up but when i loosen the injectors fuel comes out. so then a neighbor checks my distributor and it looks like crap so i replace the dist. cap, rotor, and the plug wires. it still wont start so the only thing that could be left is the coil or the computer chip thing inside the distributor. can anyone help me or have experienced a similar problem. i am about to just clean the car off, make it shiny and send it into the shop unless there is a solution, that i can do, at hand. please help!!

i'm not really sure how you get the trouble codes cuz it said something about a 12 prong dcu and connecting a pin and i'm lost at that part, or at least for today. im tired and i pulled something in my back this morning pushing the car out of the intersection. if anyone can give me a reason not to put the car in the garage it wont go in until monday. and i have to say those back plug wires on either side were a PITA to get off/on, can't wait till i do the spark plugs themselves.

p.s. sorry if i sound bitchy i'm not in the best of moods if you can tell so be patient with me

Fuel doesn't mean a hill of beans. You need to ahve a gauge to check the fuel pressure. Also, ground out a spark plug threads and put the wire on. Crank and see if you get blue flame.

I had the same problem...

I think it was the fuel pump and the fuel line was clogged. Fixed that up and its been running fine... but it was doing exactly what you described.

thankx for the help, it might just be that mike cuz i don't hear the pump when i turn the key to on. and yes aklim i grounded the wire from the coil and didn't see any blue "flame" at all, which could mean that the coil went too. the rotor, cap, and wires needed replacing anyways i just don't want to go and spend $50 on a coil if thats not the real culprit. i could do fuel lines but i definitely can't drop the gas tank on my own so i guess it'll just have to see the doctor on monday. thankx again guys, i like to know what the problem is before i send it into the shop so i can have my own estimate on costs. and i can also give my mechanic suggestions so it'll save him time which saves me money

Do you have any spark???
The "pick-up-coil" built into the distributor trigger both the Fuel and Spark, if you don't have either, it's BAD...you'll need to remove and either replace it (distributor) or remove the distributor shaft gear, pull out the inner shaft and replace the pick-up-coil...if no fuel or spark.
If no fuel, have someone else turn on the key while you remove the gas cap and listen for the fuel pump through the fill up hose. It will run for 2-3 seconds when you just turn the key forward to the run position, turn it off and wait a minute and repeat, it should run 2- seconds every time...or if they crank over the motor, it'll run 2-3 seconds after the let go of the key.

How about getting a know good wire and taking one end of it to a grounded spark plug and the other to the coil?

car just started, YAY! . it turned out to be the distributor control module located inside the distributor just below the rotor. (i believe 90rocz called it a "pic-up-coil"). i had a feeling it wasn't the fuel pump cuz every time i disconnected the TB injectors new fuel would come out even though i didn't hear the pump, also i have a full time fan so that would drown it out. well in all i spent $150 bucks and replaced some needed things. i will be replacing the spark plugs in the future, how good are champion spark plugs? i've seen em @ $5 a pop and thats middle of the road. i want good plugs w/o spending $12-$15 for a single spark plug. well thankx for the help you guys and even though my neighbor is a bit annoying i guess he does know a thing or two since he told me about the module to begin with. thankx again guys!
