That could be a cheap item to fix or it could be very expensive. Always start with the cheapest item first. Start by checking the fuel pressure, if any. The fuel pressure should be 62 lb. start and 54 lb. running. If there is no pressure or low pressure, it could be : Fuel pump relay, AC Delco 1550688....$10.11 Fuel filter, AC Delco GF845 ...$13.59 Fuel injection regulator kit, AC Delco 217-3074....$56.87 Fuel pump module kit, AC Delco, 4-door, MU 1064...$372.79 |

Replying to: jakeraven27 (Jan 09, 2009 3:59 am) That wouldn't hurt but I don't think the transmission would have any effect on starting the truck based on the symptoms you described. tidester, host SUVs and Smart Shopper |

| 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?? | |
