| I have a 99 s-10 blazer 4.3L. It recently wouldn't start...no trend no problems..........i stopped at my kid's school and when i came out it tried to start for a second and died. After that it turns over but makes no attempt to actually start. I have an existing problem i believe to be with the fuel sending unit......the gas guage doesn't work (anything less than a full tank the gas meter flucuates and doesn't go less than half a tank ever.) The gas guage problem has been like that for about 5 years. When I turn the key on, and when i try to crank it there is no "whirring sound" associated with the fuel pump running.....i swapped the fuel pump relay with the ac one (same part no.)..no luck.....i can feel the relay picking up when you turn the key on...I changed the fuel filter today....but i have to charge the battery back up to retest, however when i went to depresurize the fuel lines i found no pressure at the gauge connection or at the fuel filter (which did seem very tough to blow through). If there was pressure on the supply side of the filter i would think the pump wasn't running based on pressure already locked on that side of the system....any suggestions? | |
I'm trying to find the oil pressure and relay bypass wire/connector for the fuel pump that is mentioned in the haynes manual. Additionally i'm trying to check for voltage at the fuel pump at the top of the tank.....i can only get to one connection on the tank but i believe its for something else......maybe a pressure sensor or something. I've been judging tank level by miles driven....and initially thought i had run out of gas about 50 miles earlier than i should have....I'm not sure if it was really out of gas. I put 4 gallons in to try to start it....but have run down the battery trying...along with testing.......any help would be appreciated. I plan on checking spark plug wires for spark and then dropping the fuel tank to check for voltage at the pump....(cont'd from post 238)

| alright......I'm getting spark to the plugs....put in new plugs just cause they were due.......replaced the fuel pump/fuel sending unit....Gas guage works now......still no fuel pump running. Still don't know where the oil pressure bypass connector is. Question: How do i check the crank position sensor (i see the connection) and would it cause the pump not to start at all. After I changed the connector associated with the fuel pump i realized I didn't have small enough leads to fit into the connector to check for voltage..missed opportunity. The old fuel pump was burned up (<1 ohm, new pump is 28 ohms), and fuel level sender was bad (works now). Can anyone help me further?? | |

| I NEED HELP!!!! I Have a chevy k5 Blazer And Well To Be Honest It Gots Alot Of Problems But Its A Beast And Runns On My Way Up To School One Dat It Keep Shuting Off And Not Ideling Now It Wont Even Start At All At First I Checked The Starter to See If It Got Backed Up Or Something Thats Not The Problem Could It Be The Ingnition Wires? Wat Do I Do To Fix This? It Wont Even Turn Over Would I Have To Replace The Wiring Harness? Could I Have Fryed it Turning It On and off So Much? | |

Replying to: redneckgirl (Oct 01, 2008 12:22 pm) When I was trying to accelerate on the freeway attempting to pass another car, my RPM needle would jump and then lag back down, then I'd have push the pedal all the way down to get enugh response to pass. Try the EGR valve and get a gasket with the filtering screen on it. This way if you have tons of carbon in your manifold the EGR valve wont get clogged. If you cant afford to buy a new EGR, then try cleaning it but if it's busted, just change it and save yourself some time. If this doesn't work, get rid of it.

| Hi my Blazer will only turn over if it has been boosted or sat on a charger for several hours...if you turn it off it wont turn over again even if you try as soon as you turn it off. It has a new battery, its been in the shop for always blowing fuses and starting issues (it use to hold a charge once boosted) due to a burnt out bulb under the hood. That burnt bulb cost me enough, If someone has an idea what could be my problem please any suggestions welcome. | |

All S10 Blazers have a small amount of parasitic battery drain when the cars is just sitting without the engine running unless you disconect a battery cable. That is because the ECM, clock, sensors, theft alarms, and relays stay energized all the time. However, due to the blown fuses you have had, it is quite obvious that your car has overloads or shorts in the wiring that is increasing the battery drain, at least until a fuse blows. A bad relay will not cause a fuse to blow but it will cause a increase in battery drain. A bad relay is just like a short but is not solid enough to blow a fuse. Make sure all your accessories are working. For example, a bad power door lock relay on my 1991 S10 Blazer caused a 8 month old Autolite battery to go completely dead after the car sat for a week without being started and driven. Once a battery goes completely dead it will not take a full charge and should be replaced. I replaced the power door lock relay with a new one from NAPA and I also replaced the dead Autolite battery with a AC Delco 60 month battery. Now the Blazer has no electrical problems. I also purchased a Beltran 800 ma Battery Tender to connect to the battery in case my Blazer sits again for an extended period without being driven.. If you have a parasitic battery drain of less than 800 ma, the Beltran 800 ma battery tender will keep the battery fully charged no matter how long it sits without being driven. Normal parasitic battery drain is usually no more than 10 ma on a S10 Blazer. A good multimeter can tell you exactly how much parasitic battery drain you car has.
