SOURCE: 91 chevy blazer 4.3 won't start after running.

Check the ECM for Codes to help you find out what's causing  the problem. Here is a simple and easy way to check.
On board diagnostic (OBD) was designed on vehicles equipped with electronic fuel injection so you can generally retrieve the codes yourself. No need buying a scanner or running to any parts stores to check the Check Engine. This system is called obd1 and applies to most vehicles made before 1995 for domestics and 1993 on imports. In this article, I will discuss the methods used by domestic vehicle manufacturers on how to check the engine lights in their cars and Trucks.

For GM domestic vehicles made before 1995, the diagnostic connector is located under the dash panel by the driver side. To get the check Engine codes to flash in your dash panel, use a jumper wire or a paper clip and connect terminals A and B of the diagnostic connector. Turn your ignition key on with engine off and the codes should start to blink. All codes should start with code 12 which is one long flash followed by 2 short flashes. This code 12 means the diagnostic system is normal and will repeat itself continuously if there are no trouble codes. Otherwise, code 12 will flash 3 times before flashing the fault codes.

Counting the codes being flashed is easiest way to trouble shot problems in domestic vehicles and most of the codes can be erased or cleared by disconnecting the battery negative terminal for 1 minute and reconnect. Just make sure to check your service manual in case you have electronic equipment such as radio or clock that needs reprogramming in which battery disconnection is not recommended. Finally after performing repairs on the culprit code, always go for a road test to confirm if the problem is fixed.


Here is a link with the GM codes. http://chevythunder.com/199295_lt1_trouble_codes.htm
Good luck and hope this helps

SOURCE: engine wont start without priming with gas first, then runs well

i have the same problem on a 98 jimmy 4.3 4x4.
i replaced the fule pump and have good pressure.
new wiers & coil (good spark) no MIL & no codes.
will only start when primed. it will run & drive all day
with no problems.
but once it has been turned off (warm or cold) i will
have to prime it once again to start it.
i have another engine that was in it before it spun a bearing.
it ran fine so i know all parts are good.
i swaped the mass air flow and throttle body but i still have
to prime it everytime to start it. am i forgetting something?
should i swap out the intake with the injectors?
any help would be sweet. thanks.

You need to check the fuel press, the test port in on the rail, also run a code test on the ECM/PCM, this checks for trouble codes and also lets you know the computer is working if it tests ok.

SOURCE: my 1998 chevy blazer has been having starting

the only way to know for sure is to test fuel pressure. The test port is on the fuel pressure line on the back side of the motor near the distributor. You should have at least 57 psi of fuel pressure. Anything less and it will not start.

If you have no fuel pressure than you'll want to check for power of the fuel pump. You should be able to find a spot where you can access the harness as close to the fuel pump as possible. You'll want to probe the large diameter grey wire. It should have power for 3-5 seconds as soon as you turn the key on and anytime the key is in the start position.

Another thing you can try is spraying a little carb spray down the throttle body. If it starts and runs than this is a classic sign of low fuel pressure. The injector poppets require high fuel pressure to open when you start the vehicle. When the vehicle is running the poppets are under vacuum and require less pressure to work.

98 Chevy Blazer wont start after replacing heads


Make sure you have power to the fuel pump. On this model you should hear a quiet high pitched mosquito in your ear sound when you have all the lights on the dash panel just before you turnover the engine. If push comes to shove, take the fuel pump out, keep the power on it and run it through a bucket to see if you can at least pump water through it. Make sure you let it dry out all the way though before placing back in the tank.

Recheck the engine trouble codes (reset any in history), then try to start it again. Check any new trouble codes - probably an ignition module or ECM problem.

Wont start plenty of power sounds like it wants to start but wont fire tried listening for the fuel pump but no sound tried pouring gas directly in it and still no fire


under the hood is where you will find the fuel pump relay,just above the brake booster you should find two identical relays there try swapping them and see. if it helps. if not you will have to test the power source at the rear up by the tank is the plug, for this you will need help , have someone turn the key while you use a test light to see if power is being delivered. you will only receive for 2 seconds.if power is ther check the ground if ground is present then pump is bad.

I have a 1998 Chevy Blazer 4.3 Vortech that will not start.


You may want to check your fuel regulator and check your injectors. Had the same issue with a 96 and replaced the whole CSFI spider assembly with a MFI spider assembly and problem was solved.

The plug on the fuel pumps are common for being bad and burning up the pumps. But the new pump will come with a new plug.
