    98 Yukon will not start!?!?!?

    ok so i havent started my truck for 2 days. i finally go to start it tonite and it will not turn over. My fuel pump turns on when i turn key to start and the starter goes like it should. doesnt sound any different then any other day but jsut wont start. but when i stop turning it over it spits fuel out of top of engine? why?

    i have never ever had a problem with this truck, not one thing. and now this. my brother had it for 5 years from texas and now its in nj and i had it for 6 months, no issues. my friend took a spark plug out and tested for spark, and it was faint. could it be ignition coil? its aftermarket plugs, but looks like stock wires. much help please. thanks

    have you check to seem if you have spark to the plugs?
    2 days prior to now, were you having any problems?

    2 days prior to now, nope nothing seemed different then any other day. we tested for spark. when we pulled a plug out, we smelled it and it smelled fuel fouled. we tested for spark and it was faint, not very strong. do u think a minor tune up would solve this? like cap, wires and such. plugs are aftermarket

    I had the same type of issue. Faint/weak spark. Turns out my dist cap was cracked and throwing the timing off.

    I would look into why it wouldn't start. Before it leaves you stranded someplace.

    water in gas possibly? freezing overnight? water accumulates when you always drive around with 1/4 tank of gas
