Maybe a problem in the fuel pump circuit. Check fuel pressure with engine off, and key turned to on, not start. If no pressure, diagnose the pump circuit at the fuel pump relay. One terminal for the relay would be the power feed for the pump. The engine computer signals the relay on for 2 seconds with key on to prime the system, also signals during engine cranking.

96 blazer.4.3 ltr 4x4.new crank sensor.new fuel filter.new coil.got fuel and spark.still won't start


How about the fuel pump...are you getting the fuel to the cylinders? Is the fuel making it through the fuel line through the fuel filter? Drop a few drops in 1 cylinder, if it fires, you have a fuel problem. Does it turn over? If not check out the motor starter!

2000 chevy s10 blazer cranks but won't start????


Check for gas or spark problem on the engine. Check that starting fluid does start the car for a few seconds before dying, indicating a fuel delivery problem, like a fuel pump or circuit to it.

If the car won't start with starting fluid sprayed into the intake, then the ignition system may be at fault, or engine timing.

leaky injector/s is flooding motor, mechanically clean or replace. And clean throttle body while you are at it with spray cleaner. Should be almost spotless where large throttle valve opens and closes.

1998 Chev Blazer - Hard Starting - Sometimes Dies When Idling


If your blazer is hard to start you can spray starting fluid in the throttle body and it is under the air horn. You remove the long screw which reveals the throttle body valve but do not press it open like a caruberator float just spray it in their. It helps if you turn the key on three times and then it should start. What does this all mean; Fuel Pump! I'm sorry but blazers are infamous for the fuel pump going out. Go to www.under100dollars.com and you can find a fuel pump for your blazer for like 70 dollars. If you get it from a auto parts store it's going to be like 200 or 300 dollars. It's not to hard to due but the fuel tank strap bolts can be difficult.

Hard to start and smell gas


have 1994 4.3 cpi and the problem I had sounds same.
It was a leaky pressure line in pletium . easy fix $45.00 part $15.00 gasket.
the leak was caused from the fuel lines rubbing together in pletium.
take the vortec cover off ,then remove air regulator in middle and look inside . I turned on power to key and gas spray came from drivers side of pletium looking in hole.fuel line side. if gas spray on passanger side then gas regulator faulty. takes 5 min to check
After fixing truck runs runs great. no more gas smell in cab.
also you can smell oil for gas
