    Test both crank position sensors, they should read a resistance of .540 ohm between pins 1 and 2.
    Test for spark with spark plug out.
    Alex is fairly close to you, I built him a laptop he may let you borrow.

    Okay, let me back track some. After doing the fuel test and it the problem didn't switch side. I also checked and snugged all of the spark plugs. Problem didn't change and I also realized I left spark plug cable #8 out but it didn't make a difference.

    So after just about calling it a day, I button everything back up. Started the motor and it ran on complete limp home mode this time.

    No firing on the driver side injectors. So I decided to try 8eights fuel line switch test one more time just for laughs.

    Finally, I'm seeing a different result.
    The motor cranks but does not catch? So is one of the fuel lines starving of fuel or the fuel lines cannot be switched and still expect the motor to still run?

    Im a bit confused now.

    Switched the fuel line back to the way it should be and the motor starts...of course in full LHM.

    As sure as I can verify, Cartoonz.

    OK, you may have 2 problems, dead pump and something else. Do this, put both fuel lines in 2 coke bottles, then apply voltage(6v 1 amp does it for me but you can go v12) to fuses 23 and then 24. I bet one bottle will start filling with fuel the other one will stay dry.
    FYI, I have a refurbished fuel pump assembly if you will end up needing one.

    OK, I'll give that a try, Ed. Probably tomorrow and I have to get me a bottle of coke from 7-Eleven. We don't drink soda at home. Maybe my just empty bottle of POM might work. @:-)

    Quick question. I don't have spare MAFs and I'm thinking I should have at least one MAF in the car for backup when on longer drives or road trips. While having a spare MAF is great for testing purpose and quick swap out when in a bind, a new pair of MAFs (if affordable) is probably best for the reason of the two operating the same.
    With that said, has anyone any experiences or heard positive feedback about the Walker's MAFs for our cars or any other make/model in general?

    Here's their statement that I got from their site (under $150 per unit):

    Walker is a reputable company for emissions equipment parts - I have used their products in several of my vehicles without issue. I believe they even offer a warranty on their products.

    Do not buy Walker mafs. Walker is using Chinese single wire sensor in their mafs similar to what you find on ebay. Best bet is to buy a good used one with a 4 wire sensor.
