help! car will not start
My car is not starting. I checked the compression and its good, I installed new spark plugs, new wires, and a new fuel pump. It seem to be getting good spark. I dont know if this will help you guys but when I switch my fuel hoses around, the car starts and then shuts off and then I put them back the right way and it will not start. It almost seems like this is a fuel problem, but I have no idea what is wrong. Could this be a cause of a clogged fuel filter or a bad air filter? Thanks in advance everyone.
p.s. I did search the forum on this topic but it did not help me with my problem and I also did the flooding procedures.

test the fuel pump, before and after the filter. Its a long shot, but it maybe be clogged. Try to tow/pull/push start it. Pull all four plugs and let it spin a few seconds (bout 10-15) with them out and put them back in. If you comrpession is good (what was it btw?) then pull starting it will deffinatly get it running saying everything is good. You said it starts and cuts right off, check the AFM, make sure its plugged up and use a small screwdriver or the likes to push the pins of the plug snuggly on the AFM plug. I have had that problem as well. Good luck my man, keep us updated.

It's a new walbro fuel pump, I installed it today. Is the AFM the air flow meter? Well the car only starts when I switch the fuel feed hose to the wrong side on the engine, but then it cuts off. It doesnt even try to start when the fuel feed hose is on right.

Is this a TII? or an N/A? i think if its an N/A you might be flooding that bitch by too much pressure from the fuel pump, try putting on your stock one back on.

its an N/A. the thing is that my other fuel pump was no good b/c the car was not starting....one time i was driving on the freeway and my car started bucking so i turned to go back home, when i got back home the car shut off, so i started it back up and after a little bit it shut off once again. i went to start it the next day and it wouldnt turn on. i have been trying to figure out what it is since then, so thats why i bought a new fuel pump, wires and plugs and i also checked the compression which turned out good and its still not running. does anyone know what it could be?

Keep Right Except to Pass
When you talk about switching fuel lines, where are you doing it? At the engine or at the tank?
If you had somehow switched them at the tank during the Walbro install and are now switching lines at the engine it would be tring to force the fuel backwards through the filter and maybe it won't let it flow.
If it was flooded it shouldn't fire at all.
If it is flooded and pulling the EGI fuse isn't working, then pull the leading plugs and crank over with the fuse out, assuming the plugs were fuel soaked.
Those fuel hoses are fun huh? So damn tight.
Have you been into anything else recently?
Oh, make sure the fuel pump is/stays running.

hahah those fuel lines are pretty tight, especially in the cold. when im talking about switching the fuel hoses I do mean at the engine. i did try the unflooding procedures but the engine still does not want to turn over. any ideas anyone. thanks again for everyones replies.

what was your compression numbers exactly? bucking, like it ran out of gas im assuming, damn man, i dont know what to tell you, i would guess test this pump with a fuel pressure guage. How do you know for sure your old pump was bad? and not like an injector or afm problem? good luck to you man

Check your voltage to the fuel pump.
Disconnect the hose that runs from the fuel filter to the engine. Disconnect it from the engine and stick the end of the hose in a jar or large cup or whatever. Have someone try to start the car. The hose should be dumping out lots of gas. If it isn't your problem is most likely upstream from that hose. Fuel filter, fuel lines, pump, pump voltage, etc.

In all honesty, it sounds like your inlet to the primary fuel rail is clogged.
Since you can get it to run feeding fuel backwards into the pressure regulator, (not how they're suppose to work) and then it starts momentarily, (rail pressure basically ends up being the max the pump will put out) then it bogs and dies.
Since you're so good at pulling fuel lines. take the rails off and see if you can determin a blockage.
The walbro isn't going to cause a flooding problem in a car that didn't have one based on my experience with it. 4% correction isn't a whole lot. Thats what mine dropped the fuel enrichment from the pump. I'll be getting a better FPR sooner or later. Since I have the s-afc its not critical to gas mileage.

Oh yeah, There IS gas in it right?
If the fuel level is too low there could be enough to pressurize the lines yet not enough to feed the car. Basically you get about 12 combustion cycles and then she craps out on you till more has drained out of the return line back into the tank to give it another little squirt. Mean while you've been changing **** under the hood and think you're making progress.
Just a thought....

There is no way to check teh 2ndaries, other than getting the engine running and applying power to one of them and seeing if the engine drops rpm/dies (from being rich).

if you had massive filter failure and got **** headed up stream from the filter... it could happen.
When I wrote that originally, it dawned on me the second post about not having enough gas in the tank. I really do question the level of fuel you have. When my car gets low, it'll sputter and jerk when I get on the gas and then it'll idle but when you try to drive it will act up again.

Details, please. Did you try any of the diagnostics suggested? What did you do to start it? How long did you run it for? Did it idle on it's own?
Can't help you if you aren't giving us details...

i just took off the fuel feel hose and turn the ignition key to the start position to try and start the car. i let the gas into a bucket, then i put the hose back on and cranked it....then it started. the car seem to idle fine on itself, but like i said it did not have any power......i have changed the plugs and wires. it seems to be getting great spark cuz i took them out with the wires attached, i tried starting the car, i got a clean, blue spark from each one of them.

Don't worry about the smoke.
Most of the time a shitty idle means a vacuum leak. But, a shitty idle plus no power *might* mean a dead apex seal.
Can you get your hands on a compression tester?

My bad. 
I know squat about injectors so I can't answer that...
Have you checked for error codes yet?
No power can also indicate a clogged cat.
