2000 GMC Safari AWD Suddenly won't start

2000 GMC Safari AWD, I have never had one problem with this van till now It was running fine as usual, then took a short trip to the store came home for an hour went back out and it was like it was starving on gas and .It had been raining for a week. I tried severaltimes and it would just crank, but not start. after several key off & on sequences it would start, stumble, then run fine. Was told it could be the Fuel Pump in Tank, but you can hear it working and I can flood it while cranking, Still won't start without a lot of cranking on wet morning, so they replaced my Igniton Module. Still won't start it has been wet and cold every day on the Oregon Coast.. What is up???? I want to avoid this similiar scenario as this gut...

2000 GMC Safari, For the past year I have been throwing $ and parts at this vehicle. Last winter, It would start but run like it was starving on gas and finally ran fine when warm. When it rained over night it would just crank, but not start. after several key off & on sequences it would start, stumble, then run fine. Was told to replace the Fuel Pump in Tank, $488.00 later it still did the overnitght/rain thing. Was then told the Fuel Pressure Regulator was bad. So, got a FPR installed and while they were in there they found most of my Injector hoses were leaking/cracked, replaced them and leaking A/C compressor, $1500.00. Still won't start without a lot of cranking on wet morning, so they replaced my Igniton Module. Still won't start on damp mornings without cranking much. Has 74,000 miles on it. Now they want to replace my distributor and Computer..... The dealer says $90.00 per hour and they will try to diagnose it. Occasionally while driving the engine will just stop. restsart and it runs fine, also occasionally the ABS/Brake light comes on so I just stop, turn off, start again and it is fine.
PLEASE ADVISE

    I have similar problems with my 2000 GMC Safari. We have replaced a lot of parts in the last 3 months.



    One thing with the fuel pump and filter, the pump is higher up on the tank then the older models so don't let the tank get low. I keep it at least 1/2 full most of the time and haven't had starting problems since. I had to replace the fuel pump and filter first though - it took a long time to diagnose this because it was intermittent starting problems and never did the same thing twice. That solved it for me.

    I had the same no start problem when it rained and after 5 rotor cap replacements under the extended warranty, they found a tech bulletin that says to remove the vent screens in the distributor. Since they removed the screens, no problems.

    I had the same symptoms with my 2003 Safari, whenever it rained or was humid it acted like it was starving for fuel or just wouldn't start. If I waited long enough until the weather was drier it ran fine. After GM replaced the distributor cap four times they discovered a tech bulletin to remove the vent screens in the distributor. Since that happened no more problem

    I had same damp weather starting/running problems with my 2003 Safari. After GM replaced 4 distributor caps, they discovered the tech bulletin that says to remove the vent screens in the distributor. Since then, no more problems.

I have a 2002 Safari with around 220k miles. I went out of town for several days and when I came back it would not start. I eventually got it started after about an hour. This happened again when I did not driver it for a week. This time I could not start the van. The fuel pump was spinning and it was getting gas. I took off the engine couling inside the van and inspected the rotor and cap. They were completely corroded. I put in an after market set for less than 30 bucks and the van started right up. I plan on getting the wires and plugs replaced but I don't think I want to do that myself due to tight access. Good luck.

Okay so I have the same issue with my 1999 Gmc Safari!! Out of frustration one day I sat in the car and was ready to blow it up when I noticed that the "SECURITY" light was on every time this happened!!! I would wait for the light to go off and the car would start. I spoke to my mechanic friend and he said that if it was a security sensor problem it will reset itself after 10 minutes, and the car will start!! YOU must leave the key in the ignition and in the on position in order for it to reset. Next time you have the issue TRY THIS!! It may be your long awaited solution. This has been going on for about 5 years now for me....

    my van has been an issue as well, first it was the coil, saw sparks at night, fixed it, then the problem came back , new coil cracked again after three months. avanced auto. now its doing it again and I know Its not the coil this time and its getting gas. I know i already did cap and rotor wires and plugs not to long ago but I found that people say, if you dont replace the cap with oem, it can jump spark in the damp. one other think a guy had the same promble and it was his ingintion switch, so first think I am going to try is oem cap,

It seems like the common denominator here is rain...same with my 1998 GMC Safari - it's dead it just makes a clicking sound when i try to turn on the ignition - yesterday it was making a gurgling sound like it was drowning. But we just suffered through a ice rain storm....im praying that it dries out and works for me soon ...is it just the rain?

1995 GMC Safari Loses Power when accelerating hard, rough idle


Do you have a check engine light on? Is this a 4.3 with central port injection? If it's running real rich it might have a fuel leak inside the intake, either a fuel pressure regulator leaking or a feed line to the injector.
