Car will crank fine, but will not start.
I have a 2000 pontiac sunfire. It will not start. The computer will not read my car when connected but hasn't for several years and it had no problem running until now.
I drove the car one day (several weeks before it completely failed) and it failed on me one other time. Then it started fine in about 5 mins. I thought it was bad plug wires but wasn't sure. Then, it happened again. Same thought…then, nothing happened for several weeks. I assumed it had fixed itself because the plugs were getting plenty of fire through the wires.
Then, one evening, after about a 2 hours drive I pulled into my drive way and turned it off. The next morning, nothing. It would not start at all and that's where we are now. I checked the gas tank as it was a under 1/4 of a tank when I parked, and then I checked the plug wires again. They were fine.
The car sounds like it is going to start when it cranks. It ALMOST turns over…and then nothing. It just keeps cranking.
Now I'm at a loss.
Here is a rundown of what I did, in the order I did it, to figure out what the problem was:
~Checked Battery (charged and tried again)
~Checked plugs (recently replaced but checked the gaps anyway) and plug wires
~Checked the fuel filter
~Pulled the valve cover off and checked the valves. When the car cranks, oil shoots up through them as it is supposed to.
~Checked to make sure the fuel pump was working (it wasn't)
~Finally got the fuel pump to work after hot wiring it and now it works fine while hot-wired and when connected regularly. The pump works fine. Turn on the key, runs for 3-4 seconds as usual.
~Checked the injectors as much as we could. When we crank the car you can smell gasoline as if the injectors were working fine.
~Checked the crank sensor - replaced it just in case.
~Pulled the pan off and checked the timing chain. It is in time…put that back together.
So…ideas? Anything? Anything at all?
I have a '95 Sunfire that I just bought cheap..it won't start...it doesn't get any spark to the plugs..the mechanic I bought it from says he checked everything electrical, crank sensor, coil, etc. etc..said the only thing it could be is the ECM..(computer) so after a long search I found a new computer and replaced it....nothing, nil, zip,....he says he put it on a code reader and it wouldn't read it....I've just about had it...its sad because its really a nice car, perfect inside and out.
I am having the EXACT same problem gman50. My 2000 sunfire would act like it didnt want to start but would then eventually it just wont start. It turns over great tries to fire and catch then acts like it gives up and you just hear it turning over. I changed the plugs do to them being soaked in fuel, it fired right up. Let it sit for a couple hours.. am back to the same problem.I can also smell gas when trying to start the car. Have changed the spark plugs,plug wires, ignition module, coil packs, fuel pressure regulator, and everything else you said and it just wont start. I have come to the conclusion my plugs arent getting a hot enough spark but for the life of me can not figure out what is causing the problem. Someone please help
my stepdaughter's 99 stopped one day, cranked fine evrything checked ok i pulled the fuel lines off and had a little pressure but after that nothing. i spent three days playing with it. Just as i was about top yank the pump out my buddy said you got enough gas? It had 1/4 tank when it died i put 5 gallons in it and it started and ran great for like 3 months.
yellow security light on anyone?
check the ignition switch wires and also check the coil pack. if either of these are bad it wont start.
We are having the same problem as gmanfive0 and JoeyAdams with our sons 2001 sunfire, replaced plugs and wires, new battery... I've read the replies above, but don't see the solution, did anyone figure out why this is happening?
Is the security light on
Security light is not on.
Jump fuel pump? There is a lot of possibilities including a handful of electronic items that need to be checked and the need to jump the pump adds more to that list. Start with a noid light set and check for injectors for a pulse and check for spark. Parts may be good but they aren't doing their job BC the computer isn't telling them to
Also check fuel pressure. At a low pressure the engine won't start BC there isn't enough gas and since its getting gas but its very little it will smell like raw fuel.
OK folks. Here's what I did... After doing all the stuff above, I went and purchased a brand new fuel pump. It worked fine after that. The plug wires that I purchased previously were faulty and when I checked the plugs again, they actually fell apart. So, I took them back and exchanged them. The new ones worked fine. I changed the plugs just in case. The largest problem seemed to be with the electric in the car and still is. Here's what's happened since I changed all that: The car AC burns through AC switches like none other. The Master Control switch on the steering column is bad as well and this causes no high beams to come on. The car does bog down a little bit when given gas but it's not super bad. Finally, the lights on the dash come on and stay on no matter what I do and the computer will not be recognized by my reading apparatus. In short, the electric is the biggest problem with the car and not an issue that I want to tackle. So, I figured it was just time for a new car. I fixed it up as much as possible excluding the electrical stuff and gave it to my dad - master mechanic. He's using it as a utility vehicle now.
My 2001 Sunfire does this as well. The fuel pump is going out on ours. We have to 'pump' the ignition. turn it in the 'on' position then back off.. then back 'on' position then off.. do this a few times THEN try starting it. sometimes takes longer than others.
My sunfire 2001 6c I run out of gas put some in it but wont start and its been setting over night
I have a 2000 sun fire, have installed a new alternator, a new starter, a new timing chain, a new battery new spark plugs, was running great, until the other night it stalled while I was driving it, and cannot get it to start...fuel pump sounds like it is running, it cranks just won't start :( any advise??
I am having same problem but I have a 1999 and everything seems to be fine the security are flashing and I Changed the switch but still no start could it be the cylinder
Cherielin have you reprogrammed the security system? Attempt to start the car and then leave the key on for ten minutes, light goes out turn the key off and attempt to start, sometimes it starts sometimes you have to do that 2 more times
I had a bad resevor so I replaced cranked the car let it run for 5mins went out there the next day and it wouldn't start..the motor smells of gas every time I try cranking it..it turns over but will not crank..i replaced the spark plugs, the fuel filter, checked the fuel pump and it works..when I checked the plugs one was broke so I replaced those and one of the new ones broke..but when I put them on it still wouldn't crank and I don't have a clue whats wrong with it
I might have an answer I have a 2001 Sunfire works and runs great until my dash gage cluster started blowing lights and I have been trying to change them and now went to the bone yard and got a new gage cluster so have it checked
