| i got a 2001 silverado 1500 and it wont start it turns over and fires and then dies right away i kept it started with starting fluid for a few seconds just to make sure it ran it did anybody got any suggestions | |
| My 95 gmc 1500 350 has stalled out every so often when comming to a stop for over a year and normally starts right back up. This time it won't start. Ive changed plugs and wires , cap and roter, and ignition control module. Turns over fast but won't even attempt to start. I know it has no spark but not sure if im getting fuel. I've tried starting fluid but still nothine. I was thinking maybe replace the ignition coil and distributer next??? Thanks | |
Driving and all sudden lost all power and died. Would turn over but not start. Had towed. All gauges light up but my fuel gauge went to empty and I had plenty of fuel when I was driving. Checked all fuses they seem to be fine. I will run test but wondered if anyone has any idea. Put a new fuel pump on about a year ago, and heater core connectors and other than u joints and brakes and keeping oil and filter change, I haven't had any problems. Does have alot of miles. Any ideas??? My check engine light did come on a day ago but went out. Kablelynn

I've been desperately searching for answers online and have read all 103 posts in this forum - I'm leaning towards fuel pump at this point, but at around $250 and with the requirement of tank removal I'm trying to really be sure I get this right; I'll keep you posted. For now though let me share what the last 4 days has shown me. Vehicle: 2004 Silverado 4WD 5.3 Z71 fully loaded Anomalies: We've had colder than usual temperatures and a lot of snow and ice here in Salem, Or for the past week - other than that it's life as usual. The facts: - Pulled in to work Monday and shut the truck off - An hour later went out to start the truck and all it would do is crank, no fire at all - After a half hour of screwing around it finally started and ran fine - Over the next 6 hours I had intermittent problems, it would always crank fine, it wouldn't always start. When it did it ran normal. - Called the dealer and a tech told me that he was 99% sure it was the fuel pump, "save yourself $95 of diagnostics and just buy one and put it in" he said. (NOTE) New fuel pump prices range from $200 to $542 depending on OEM vs aftermarket and the parts house you call - I decided that a $95 check was worth the investment and took the truck to the dealership for testing. - An hour and $322 later I pulled out of the service bay with a new crankshaft position sensor - "fuel delivery system checked out OK, but your battery is showing some weak indications, we suggest you change it before it leaves you stranded. It could also be part of your sensor problem." - Ran the truck 2 days, no problems, an occasional rough idle was also gone - Yesterday morning (xmas) I spent 3 1/2 hours clearing my elderly neighbor's driveway. The truck was either idling or running hard in 4wd for the duration of the time while I cleared down trees and made my way through a foot of snow going up their driveway. The truck gave me no problems. - Afterward I made a few trips to town and everything runs good - Now, this morning....walk out to the truck and hit the keypad to unlock the doors; nothing. I unlock the door with the key and then hit the button on the arm rest to unlock the door - nothing. - Put the key in and the truck barely starts due to the battery being weak. - I let it warm up and let the battery charge for about 15 minutes and then shut the truck off and try to restart it, for some reason thinking that the door locks might reset or something. I also notice that my fuel gauge is on E, so I add some gas thinking that maybe I ran it out and didn't notice. I added about 5 gallons and the gauge didn't move. - I turn the key and the truck fires and dies with every turn of the key. - I don't have a fuel pressure gauge but I pushed the button in on the fitting and when the key is turned on or cranking there is LOTS of fuel spraying out. - I pulled the weak battery and get the old man to give me a ride down to swap the battery, Schwab's tests the battery and finds nothing wrong, but agrees to warranty it since it gave me problems early in the morning. - Installed new battery and the condition is the same; cranks, fires, dies. That's my story. I'm stuck with 10 inches of snow on the ground with a dead truck and a B-Mer that can't clear the ruts in the driveway - what a deal 'eh!? Next move: a buddy of mine is picking me up shortly, I'm going to buy the on board diagnostics (OBD) software kit from the local parts house and run a full check, if that doesn't surface anything I guess I'm pulling the tank and changing the pump assembly. Something just clicked; the fuel gauge sending unit is part of the fuel pump and in-tank filter assembly, I suppose there could be a connection or a supporting indication here since the engine seems to be starving for fuel (only firing briefly and then dying) and my fuel level indicator appears to be stuck on E when I know there is at least 5 gallons or roughly a 1/4 full tank. Replies are welcome but this has been more of a venting session and a sharing of information than anything else. It does appear that most of the posts are symptoms only with little mentioned about final outcomes, so I will re-post with results as they become available. Anyone interested in a '04 Silverado? Will trade for a pre '80s Ford or Chevy 3/4T pickup of which I can diagnose and fix with screwdriver, some duct tape, and a volt meter....  WELL IT'S TRUE!!!! Thanks for reading, more to come.

Replying to: Distilled (Dec 26, 2008 11:39 am) First of all, a little more information on what isn't working. In addition to my door locks the seat heaters, window controls, and the radio are not functioning. When the key is inserted and turned to ON the HUD lights up but says; UNKNOWN PASSENGER and when the shift lever is moved there is no indication as to what gear it is in. When the key is turned off a variety of jibberish type characters appear at random. That said, I couldn't get myself to believe that the fuel pump was my problem, so I went and purchased a fuel pressure tester and an OBD II engine scanner. Pressure indicated was 62# at the initial turn of the key and 55# while cranking which is within the specifications I have found. I plugged in the OBD scanner and it could not make a connection; key on or off it just kept saying; "Trying to establish a communications link" I tested the unit on another vehicle and all scans completed with no error. I've tested every fuse I could find for continuity and they all checked out. I tested every applicable relay skipping only those that referenced something like head lights or fog lights. I tested all fuses that I could find, that even seemed to relate to the ignition system, for voltage; I don't know the the exact voltages required, but all those tested had approximately 12V showing, +/- .2V or so. I'm stumped. The only thing I can believe is that one of the modules has gone haywire, it is my understanding that there are at least two; PCM (Powertrain Control Module) and the BCM (Body Control Module, which I believe to be a sub-system of the PCM) I guess I'm going to have to break down and take it in to the dealer for another $95 verification. It is my understanding that a PCM replacement with relearn is a spendy repair, so I'm hoping they find something that I've over looked....... a blown fuse would be nice...... an expensive oversight, but nice.

Replying to: Distilled (Dec 26, 2008 4:06 pm) Short version: Connectors at the PCM were checked and corrosion and water was found, the connections were cleaned, greased, and reinstalled and she fired right up. I got the truck back last night, the only pending problem I've noticed is that the XM radio, which was factory installed, does not come up as an option on the radio. Other than that it's running like top. |
