#56 of 157 00 Safari difficult to start
Jan 22, 2008 (4:41 pm)
Hello, My 2000 GMC Safari is very difficult to start. If it is jumped or if the battery charger is on it, it starts easily. It starts best usually if you just bump the starter. Cranking will only assure you it won't start, but just drain the battery. The alternator and battery were changed early fall. The alternator was just about stuck at that time. I have always wondered if the fuel pump was weak. It doesn't seem as loud as before when you first turn on the key. Do I have two seperate problems or just one? The spark plugs, coil, Cap and rotor were new last summer. What do I check next????

My 2001 AWD didn't want to start last Sunday either. First time it didn't start for the last 3 years. Its battery cranked and cranked its starter, it fired a few times but it wouldn't start. Like an old tired frozon dog that didn't want to get out of bed. Left a portable electical heater under its hood and one under its engine for a 8 hours, and re-charged its battery. Even plugged in its block heater for even more good luck. Then, she fired right up under a 5 second crank. I'm thinking bad gas or frozen gas in its system. Might want to give your van better gas or change to a different gas station. Worked for my van.
BTW: For the Safaris/Astros, it is recommended to keep above 1/4 tanks of fuel. Above 1/2 tank is best. And. park on hills facing downward. Thus, it puts less stress on their "weakly designed" fuel pumps. Works for me...

Thanks, but the problem seems to go deeper than that. I always keep the tank above 1/2 a tank and have put fuel injector cleaner in it just about every fill. Living in IOWA it sees ethanol all the time also. It could be a weak fuel pump, but then why does jump starting it or leaving a charger on it help so much? Please reply if this further information helps, Thanks Mark.

Last week, my van wouldn't start. Thought it was bad gas / water in the gas. Took to my van to local auto shop and they changed its rotor and distributor cap. Talk about electronic corrosion overload. They also changed its battery. Unknown to me, they said its existing 6 month old battery would only charge up to 90%. The 4.3L engine needs 100% charged battery for best cold morning starts - even when its 90% charged battery can easily crank its engine. So, they changed these 3 items. For the last 2 cold mornings, my Safari van "fires right up". As a suggestion, get your local auto shop to investigate these 3 items as well. Worked on my 2001 Safari van...
Hope this helps as well...
#60 of 157 Reverse Lights not working (2000 GMC Safari)

Hello, I have a 2000 GMC Safari w/ the Mark III conversion package. The issue I have is my reverse lights do not work. I've replaced the bulbs and it is not the bulbs. Where do I go from here? Anyone have any pointers?

That would be the PCM and to get the part# you will have to get it out and look for it on the computer itself

Check your neutral safety switch located on the driver side of the tranny

Check the air box on the pass. side of engine compartment locate the blower motor the wires coming out of it follow them and it will lead you to the blower motor resistor

I have a 92 Astro that you have to push the headlight switch several times to get the headlights to turn on. Before I tear into it, I was wondering if there might be a relay that the light switch turns on or does the switch carry all the current? If there is a relay, where would it be located?
