Check for cam/crank position failure. Run fault codes to determine fault.

You need to check and make sure you have fuel pressure, then check for spark at ignition, if those check out then check for pulse width at the injectors. That basically is the electrical signal which tells injectors to spray fuel. Use what is called a Noid light on injector pulse width check. that will eliminate all possibilities other than internal issues with engine. I.E. broken cam, broken timing components, obviously if all I mentioned checks out then run compression test. Good Luck

SOURCE: TWO DAYS AGO 94 RANGER (4 CYL) SOHC...STOPPED ON

If all the coils are giving spark now,then you moat likely have gas fouled plugs now,so change them out with new ones,all 8 of them.If you do not have spark on all plug wires,pull the timing belt cover,and align the cam shaft and the cam,to see if the belt has jumped.If It hasn`t,replace the crankshaft sensor.

My 98 chevy blazer just got a new fuel pump and filter. Wont start even with starter fluid into the throttle body. Any ideas?


If it's a gasoline engine, please check for sparks at the spark plug end. If it's a diesel, check pre-heating system. Starter fluid in the throttle body must be ignited by the spark plugs. For diesel, pre-heating is necessary to ignite the fuel.

94' blazer will not strart just died one day while driving it .i replaced fuel pump,fuel filter,fuel ragulater, if you spray starting fluid in it it will start but then die whin the starting fluid burns...


check to make sure they sold you the right fuel pump. they are two pumps for a 4.3 ones a vortek and one is a throtlle body. the eighth digit of the vin will tell you one is a vin w and one is a vin z. the throtlle body only puts out about 11psi of pressure and the vortek puts out about 60psi of pressure.if you put the throttle body pump in a vortek engine there is not enough fuel pressure to run it.

I have 91 chevy blazer s-10. and it tries to turn over and i can see the injesters spraying fuel but i took a spark plug out and it was dry and ideas?


check another spark plug first off,if more than one are dry could be a possible broken timing chain, remember even though its EFI it also still uses valves,its also possible you have bad fuel.try a shot of starter fluid thru throttle body....if it starts after that consider draining fuel tank and adding fresh fuel, its also possible you have a timing issue where as the fuel is burning off plugs but not powering engine

'94 S 10 Blazer V6 Vortec EFI. Fuel pressure good, new fuel injectors installed, fuel pump works ok. Only starts with starter fluid sprayed into air intake. Any Suggestions?


your statement is fuel pump work ok, have you tested for proper fuel pressure. just because the fuel pump works it could have less pressure needed to start the engine. maybe the fuel filter is plugged. start out by replacing the fuel filter, if this doesn't fix it, you need to pressure test the pump. even 10 psi reduction in pressure will allow the engine not to start.

2002 Chevy Blazer, car will crank but not start. Just changed the fuel filter and sprayed some starter fluid in the hose and the car started for a few seconds and then died again. Is there any way it could...


it could be a fuel pump they are quite common on the chevy trucks and SUV's. If it has a "Vortec" engine which it probably does, they run whats called a poppet nozzle fuel injecter that requires i think no less than abaout 53 psi of fuel pressure to run, you would have to put a fuel pressure guage on it to be sure and they are quite expensive

1999 chevy blazer wont start


THE FUEL PUMP IS BAD.

if your losing fuel pressure after the pump runs the drain back valve in the pump has failed.

and i doubt that you are seeing enough fuel pressure to run a vortec engine.

low fuel pressure equals a non running vortec
