gmc sonoma starting problems...please help!

Showing 6 out of 7 Posts | Show 1 Hidden Posts
Question From n_webb08 on gmc sonoma starting problems...please help!

i have a 2000 gmc sonoma 2.2l automatic. its having problems starting, it will crank but it wont start. sometimes it seems if i have the gas pedal to the floor it helps it start but that doesnt seem to make since seeing if u have the gas pedal to the floor it shuts the fuel injectors off. i replaced the battery but it still doesnt seem to help too much. when i get it started have it running for awhile drive it shut it off then try to start it right back up it will start fine. idk if the cold weather is having anything to do with it. also i have codes for throttle position sensor and o2 sensor not sure if that would have anything to do with it starting. please help me!

Response From re-tired Top Rated Answer

Clear your codes and see which returns. Possable faults could be leaking injector(s) when eng shutoff . Going into clear flood mode would help unflood eng. Or a out of wack temp sensor. If the code for the TPS comes back It needs to be checked with a scanner or dvom meter.

Response From Discretesignals

Security light on or flashing when your attempting to start it?

Response From toolman0007

I would check your temp censor and plug end GM's have a issue with corrosion. full flood mode start or hard start cold or hot are common connections with the temp censor it the first in line to tell the system how much fuel to deliver. been down this road

Response From Hammer Time

Stop responding to old questions.

Response From n_webb08

no security light comes up when i try to start it. also i should mention that when i keep trying to starting it there is a faint smell of gasoline under the hood so the leaking injectors idea seems like it could be a possiblity. if that was the case what would be causing that....bad o-rings on the fuel injectors maybe?

Response From Discretesignals

If you had a bad top o-ring, you would see fuel leaking externally from the injector in question. If the bottom o-ring was leaking, you would have a vacuum leak.

Another possibility is a fuel pressure regulator leaking from a ruptured diaphragm allowing raw fuel to enter the intake manifold. Pull the vacuum hose from the regulator and inspect for raw fuel.

1996 GMC Jimmy fuel injection

Question From kingfish on 1996 GMC Jimmy fuel injection

1996 GMC Jimmy 2WD with 4.3 Vortec eng very hard to start after sitting overnight unless primed. After first start of the day it starts fine and runs fine. Could it be that the fuel pump is losing its prime? Fuel pump relay was replaced.

Response From kingfish

Thanks to all who have offered suggestions. I should have mentioned that once it starts, it will start as it should unless it has been sitting for a long time, such as overnight. The strange thing is that for the last few days it has been starting as it should, even after sitting overnight.

Response From Tom Greenleaf

Note that available power from a battery is VERY temperature related. Ever notice the acronym CCA? = Cold, Cranking, Amps. I suspect the battery (or excessive load by starter motor) may be the problem new or not and whether tested good or not!! You need to watch the voltage drop while cranking,

T

Response From azrael

sounds like a pressure leak. Were your fuel lines disconnected at some point.

Response From kingfish

No lines have been disconnected since I have owned it. That's been a year and a half.

Response From Tom Greenleaf

?? Thinking by keyboard on this. I'd try leaving a jump start on this from a running vehicle and bet it starts right up. Reason - I suspect cranking voltage drops too low to power the fuel pump to proper pressure. If that does work it could still be tricky to isolate just what is the exact problem??

T

Response From dave284

Just to add, have battery tested at autozone and while you are there rent a fuel pressure tester to perform leak down test. two birds with one stone.right guys

Response From Double J Top Rated Answer

I"d be lQQking more towards the fuel injector itself........they had technical service bulletins on this as well as a recall from what i remember...

starting issue 1993 gmc safarri

Question From david1950 on starting issue 1993 gmc safarri

found cause for engine not turning over,number 3 cylinder. full of gas.Pulled all of the plugs and none of the others have this problem.Engine turns over fine with the plugs out.Number 3 cylinder. sprays gas out,any ideas??
I really need some ideas on this please.........

Response From david1950

Thanks a lot for your help. I am going to remove the manifold. what is the best way to identify the problem, if i can't visually find it? Can parts be replaced or do i have to buy the entire CMFI assembly .Any idea on the price? Should this be bought at the dealership?

Response From Hammer Time

For that one I believe it's a whole assembly only. You should be able to see the gas trail. It will be the clean spot.

Response From Tom Greenleaf

Does whatever engine have one injector for each cylinder? If so it probably has one the way over fuels and leaks. Gotta get right on this as the engine now is hydraulically locking and the fuel will wash lubricating oils from cylinder wall AND can easily pass on and contaminate engine oil. Check that NOW - it may smell and read too full! Doesn't take much raw gas in oil to make it useless as engine lubrication - critically important of course,

T

Response From david1950 Top Rated Answer

It's a 4.3w motor,with cmfi with a single fuel injector which feeds 6 poppet valves.So far no gas in oil

Response From Hammer Time

You most likely have a bad regulator, line connection or injector. The #3 cylinder is the point where all the gas flows from that area. If you pull the upper intake, you should be able to follow the clean trail right to it's origin.

Response From david1950

from my chilton and haynes manuals they state no repairs can be made,on the cmfi assembly.Therefor what can I actually repair under the manifold?It's in a safari van and every thing is very difficult to get to....I would like to fix it because it runs great uses NO oil and is all wheel drive.

Response From Hammer Time

If there are no problems with the line connections, then your going to have to replace the injecter.

1992 GMC Sierra 1500 wont stay running

Showing 2 out of 2 Posts
Question From slrivard19 on 1992 GMC Sierra 1500 wont stay running

Ive been working on my 1992 GMC Sierra 1500 4.3L V6 trying to get it running. First my starter was going bad and I had to push start it for a while to get it to start but then one day I went to go start her up and she wouldnt start. I had to replace the starter to check for spark and it turned out that there wasnt any spark. I then replaced the ECM and the coil. After replacing those 2 items I turned her over and she started right up. I drove around a little bit and then out of no where the truck died. After sitting for a little while it started back up. After I got home I later tried to start the truck and it wouldnt start. I put a little bit of fuel into the carborator and the truck started but then instantly died . I removed the cover to inspect the fuel injectors and it turns out there is no fuel being sprayed by the fuel injectors. Before replacing the coil and the ECm the injectors worked perfectly fine but now they arent working. Any clue on what the problem might be? Ive checked the fuel pump fuse and it is fine.

Response From Discretesignals Top Rated Answer

You need to find out what the fuel pressure is. On those you have to T in a fuel pressure gauge down at the fuel filter. Normally they should have around 13 psi on a TBI system.

Question From cmh on car hiccupps in heat

I have a 1988 gmc jimmy I just recently replaced the fuel pump, the plugs, wires, air filter and added fuel injector cleaner. It was running great and still does except for the hiccupps.Since it has been hot it seems to miss or hiccupp. It doesnt do it when cool outside. It doesnt get hot or over heat. Can anyone help me??
Thank you in advance

Has that problem start only since doing the tune up?

Is the check engine light coming on at all?
