I need some help on where to go from here... I need this thing to start by the key bad....

 

might want to consider revising that it doesnt really make sense.

 

So, you have a problem with the starter or maybe the battery is not at it's best.
Once you said that it bump starts easily there was no need to list everything else because it's irrelevant.

Check the battery first, fully charged?
Check condition of the wiring to the starter.
Finally, swap out the starter.

 

it cranks over fine have had the battery charger on it and it cranks over fine... It acts like it wants to start it just wont catch...

 

Check the AFM...it sounds fishy.

 

I have checked it at the ecu and checked out ok at the ecu.. but goin to check it out completely tomorrow when i get off work...

 

makes perfect sense...

 

What's the problem your having with what he wrote???? He wrote " it won't start if I push it five feet and pop the clutch" and goes on to say " it fires up and starts right up". Perfectly clear to me. What part of "it won't start" and what part of "it fires up and starts" do you not understand???? Hmmmmmmmm, maybe you've got something there.

I'd say low compression issue that will improve once you get some ??? five hundred or so miles driving on it. Basically flooding during the start with low compression.

 

well I checked out the afm yesterday when i got home the book says that the e2-vs should be 50-500 ohms when i checked it my multimeter says i have .280 kilohms and e2-vref is 200-500 and i got .281 kilohms... and at wide open e2-vs should be 50-500 and at wide i got .022...

Does that mean the afm is shot?

 

is that my problem?

 

First thing you need to understand is how much is a kiloohm. A kiloohm is 1000 ohms. So a reading of .280 kiloohms would be 280 ohms. Thus .281 is 281 ohms. And .022 would be 22 ohms.
