cant do that- has to run through maf sensor to stay running- i thought it wouldnt start??

it will start every once and a while. Once it is running it runs fine. It is just a matter of getting it to start

how old is the fuel filter?? sounds like the pump is weak- hard to start cold??

filter has around 5 years on it and the pump was replaced last summer.

yep start with the filter (plugged) - it should be replaced more often- check the fuel pressure- there should be a shrader valve on the fuel lines- i can look tomorrow for specs at work or google it - maybe someone can chime in here- but i think it should be all of 50psi- good luck- Chris
