| 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?? | |

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.

We were driving for about 20 min and then it died so we pulled over tried to start it and it wouldnt start. it then started shaking and backfiring. We recently replaced the fuel pump and gas tank. Anybody have an idea as to why it's not starting?

Replying to: bedard (Feb 22, 2009 7:54 am) Several things could cause this, a MAP sensor being one of them. Generally speaking, the vehicle has suffered a hard failure and if it is sensor related you should have a code stored. Other concerns would be jumped timing from a worn timing chain/gear set. Also an ignition issue from the distributor.
