If a 2000 GMC Safari stopped running and now will turn over but not start what is wrong?
Note: The sympton with my van was it started but started to require a few trys to get it started....then it required 4-5 trys. Eventually I could not get it started. If I was able to get it started it stayed running and ran fine.
At the risk of sounding like my dad, any internal combustion engine requires three things to run: -Fuel -'Fire' -Compression
Sounds as though you're looking at the most likely problem areas.
Some additional input:
-Fuel: Just because you replaced the fuel filter, that doesn't mean you're getting fuel. If you've replaced all that other stuff without blowing anything up, try disconnecting the fuel line at the point where it enters the carb/injector system, stick a can or fuel-proof container under the end and try cranking the engine a couple times. If nothing comes out, you've got a bad fuel pump. (As previously mentioned in some of my GM related rants, the fuel pump is in the gas tank. Good luck.) -'Fire': Using a thick glove or rag, disconnect one of the plug wires and hold it close to the engine block while someone cranks the engine a couple times. If no electrical flash between the plug wire and ground, you're still missing something in the ignition system. -Compression: Probably not an issue, unless you've already confirmed you've got fuel and 'fire'. Even with a blown head gasket, the thing should try to fire and maybe even run-roughly.
First thing DONT EVER hold the spark plug wire with any part of YOU when cranking over the van or any car .if it there is a very high voltage that can kill you before that the easyest way to test the fuel pump is to have somone turn the ignition to on not to start just till the radio wiper work but of couse have them turned off so you can hear . listen right at the gas refill door if your FUEL PUMP is working you will here it prime for startup.. If you dont here anything then start cheking fuses if all fuses are ok then your pump is fubar Iv had to replace mine. Just remember its either gas or electrical that will stop your vehical from starting .After rereading your Q if it starts and runs and stops and will not start again that sounds like the FUEL FILTER had that happen to me too. The fuel filter when cold at first start it allows fuel threw butt after fuel passing threw the filter heats up by friction and swells up making it inpassable IE no start but engine crancks but wont start that is the first thing to check from what you discribed good luck
What could be wrong with the power steering and breaks are vibrating really bad on 1999 safari what could be wrong?
Your car makes a loud roaring noise that gets louder with acceleration and when you turn to the left in curves it stops what is wrong?
How do i get my best guy friend to start talking me after he just stopped and i don't know what i did?
What is wrong if you start your car but then you shut it off but it stays running and yes its the engine that is running?
What would be wrong when a 2001 Toyota corolla start making a knocking sound when AC on and accelerating?
What is wrong with a 2001 Nissan Xterra if the blinkers stopped working and the flashers still work?
Why does my Nissan Altima 2004 running fine stopped to get gas wouldn't restart for one hour started ran fine stopped again now it will not restart for 2.5 hours what could be wrong?
Your Safari van continues to miss when driving you have replaced several item including mass air flow sensor map sensor coil plug wires rotor button erg valve etc What else could be wrong?
I am the owner. We recently took the GMC Safari Van to have the diagnostics run on it. NOTHING wrong!!! We had them do an injection system clean up on it. It seems to be running smoothly now. We never found what problem caused the missing problems. If this injection clean up fixes this problem lease try this on your GMC vans also. thanks for helping.
When you start your car in the morning it wont stay running you have to hold the gas down What is wrong?
What could be wrong with a 1998 GMC Safari van that makes no sound at all when you turn the key and won't start?
What could be wrong if the low beams and high beams stopped working on a 2000 Toyota Tundra but the bulbs are fine and the daytime running light and the parking lights and blinkers still work?
Yes in the wetland part of the safari zone but you have to arrange it to get the wetland and you can find a ditto on a waterfall, near the safari zone entrance, take the wrong way and go to the bottom floor, move to the left then up. Keep going in the grass until its there. But honestly you cant find a ditto in safari zone...
What is wrong if your fiber optic tree motor that turns the light wheel stopped working and a little oil did not help and the light works but the color wheel does not turn?
If you have the wrong leads going to the wrong spark plugs, then you will have a spark when the cylinder is somewhere other than where it should be, which is at the top of the compression stroke ready to drive the piston down and provide power. If you can start your car, it will be running very rough, have no real power at all and your gas mileage will be measured in gallons per…
something is wrong on the right side of your vehicle, its hard for me to tell you exactly what could be wrong cause i cant hear the sound but i would start at the spring and examine everything from the spring down very closely, but if i had to guess i would say it is probably a control arm or trailing arm
As I had turned the gas switch off on my Yamaha 400 Big Bear and forgot to turn it back on then drove it until it stopped and now I can't get it to start even with gas and choke on what can be wrong?
What is wrong with a 2001 Astro Van that stopped running suddenly and will not restart if the sparks are getting fire and the fuel pump runs normally?
An engine needs 3 things to run. Air, fuel, and spark. You are either missing one of these or it is firing at the wrong time. Just because the fuel pump is running does not mean it is pumping fuel to the injectors. A clogged fuel filter comes to mind. Could be the pump is bad and not really pumping any fuel. Check to make sure you have fuel. change the cap and rotor
