Question
Malacca
I am new here. Haven't posted anything but will post my one trick for GM turn signal flashers.
2004 Suburban 1/2 ton. Bought with 92K on it. Now 177K. Flex fuel if that matters.
Been a great vehicle. I spent time in MN and great vehicle for the snow. AWD rocks.
MN got too cold so headed to Southern California. Dragged a 6X10 trailer full to the brim (Suburban, too) - no issues. A real champ.
Came back to MN for the summer and Suburban - no trailer - seemed weak in mountains. Crappy vehicles passing me up.
Then about a month ago suddenly it would take a few more seconds to start when cold. I figured I needed a tune up. So I bought plugs and wires and had my mechanic (works out of his garage) put them in. Turns out it had the original plugs and wires. I guess the first owner didn't do a tune up. 177K on them. Wahooooooo
Anyway, truck had more power after tune up.
But this morning had the same hard start (only when cold).
Read the forums. It seems many people have the same issue - but the solution is not clear. Some people changed everything but still have the issue.
Bad regulator? Bad fuel filter (which means fuel pump on my vehicle)? Water in tank (I did lose my gas cap recently)?
I did the 'turn the ignition on and off a few times' trick and that helped.
Of course we all know the drill - if it is a fuel filter then have to rip apart the gas tank and replace the fuel pump - BIG $$$$.
It really isn't an issue. I could live with a few hard cold starts. But it probably will get worse.
any ideas?
Kind Regards,
Malacca
