Kinda OT but....

My 95 GMC seems to turn over alot (6-8 times)before firing in cold weather... any suggestions on whether it's an ignition prob or how to get it to fire sooner?

my 69 turns over atleast 15 times so i would consider you kinda lucky. But i think mine is because i dont have a choke.

Yeah, colder weather is upon us. I can tell because my truck needs to be started twice now. Seems to just bog on the first try. But I like to warm up the truck naturally, ie. letting the choke do its thing, not like my neighbor. He fires it up and then "forces" it by leaning into the gas. Not good for the engine and I keep trying to reason with him but some habits die hard.

You can wish in one hand and crap in the other.

The TBI will take a little longer to fire up. Are you holding down the gas pedal? If so, that could be one of your problems. Holding down the gas pedal in an FI vehicle will enter the "clear flood" mode. It basically has the throttle wide open and allows more air to enter than fuel. This is used in case the engine flooded. I hope this helps. John

whens the last time u had a tune up on it maybe it needs plugs, wires and a fuel filter. You can press the gas pedal on a fuel injected, about 1/4 of the way down is enough, it will not enter clear flood mode as suggested. clear flood is entered when the accelerator is held to the floor.

Mine always fires first try, even in the cold. This morning it was realy cold and fired right up, it must have been 68 degrees outside Brrrr!
Sorry, couldn't resist. We tolerate the heat for months on end just to get weather like this. I think it cooks our brains too.

My wife's truck (2000 Silverado) was starting hard too. It turned out to be a collapsed fuel line.

I was curious if you guys in Canada use block warmers on your old trucks?

One thing to look at Shawna, do you hop in and crank it over, or do you hit the key, let the fuel pump prime the system, and then crank it?
If you do the latter, then try waiting 5 seconds after hitting the ignition before cranking it over.

Have you checked the battery for age and cranking amps.....

The duck on the right may have a bad attitude........but the one on the left is either drunk or is accident prone........

Ms. Dubie,
I have a 95 GMC Jimmy (4.3 w/CPI) that was doing the same thing. Mr. Goodwrench said the EGR valve needed to be cleaned and the gasket under the CPI replaced. Said that some crusty stuff was preventing the injectors from shutting off completely, so it would bleed off all the pressure in the system and also drip raw fuel instead of atomized fuel.

Your TBI is probably different, but it may be worth a shot to clean & check the EGR and see if anything else on the TBI is crusted over.

Good Luck!
