engine turns over but won't start by john2295

1996 chevy blazer..
Engine turns over but won't start..I'm not to much of a mech..But I can swap parts if I know the right direction to go..
Dies this sound like a fuel pump or filter issue? I don't have anyway to test fuel pressure..But if swapping a fuel filter can save me from spending bigger bucks to swap a fuel pump, I will..Or am I looking in the wrong place?

My blazer is definitely doing the same exact thing right now. Well what happened was it was doing the same exact thing and then after about a week of that it started actually missing while i was driving a steady speed where as originally it only did it when i was idling or coming to a stop. Then about a day after it started doing that it just shut off, and then it wouldn't turn back over, it just cranked and wouldn't fire. I replaced the spider injector and it ran wonderfully for about a week, then i got out of work one day and it wouldn't start, the fuel pump went. I replaced the fuel pump and its been about a week now and just yesterday it started up with what it was originally doing again, where if im not driving at a steady speed it wants to die, so i guess the fuel injector was not the problem in this case although maybe it is in yours i don't know. i don't know if im caught in a continual circle of part replacement or what, but if anyone has nailed down the exact thing that causes this i would greatly appreciate it if you would let me know before it dies completely on me again : )

Having problems with Fuel system by v_bunnies10100

I thought putting in a new Fuel sensor would fix the problem but still won't start. Could it be the emissions? How would I get that checked? could I do it at home? I have a 2003 Blazer. Drove it home one day and it just shut down, like no fuel was getting to the engine. Niw it won't start at all. Was there a recall on this in 04 and 05? Please reply, Thank you v_bunnies1010

fuel problem by duntov

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

I would think that your fuel pressure regulator is bad, did you replace that too? also mybe the crankshaft position sensor.

Did your mechanic check the starter gears?

No i have not yet but plan on doing that today,Also after i had the truck tuned up i changed the plugs and the wires it ran like new but only a week latter it started missing again,I am afraid the transmission may be going out what else could it be i know i have fluid.Would a diagnostic test tell me if the transmission is going?Thank you for your time and your help it is appreciated so much.

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.

99 blazer wont start..fuel pump doesn't run by allenax78

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?
