    There is a Fuel Pump Relay under the hood with the rest of the relays, and I can't remember offhand which fuse is linked to the fuel pump. The Fuel pumps on these are known to fail relatively frequently though. That would be my first guess at it, the regulator Should be right off the t-body to the...passenger side I think. I havn't seen one of these with a t-body in the last year and even then I think maybe 1 before that so not terribly familiar with them.

1990 chevy blazer 350 ci throttle body fuel injected . the motor is flooding out u can see the injectors keep dumping fuel into the throttle body


Sounds like you have an injector leaking. Have someone just cycle the key on and off to run the fuel pump but don't crank the engine. If you see fuel dripping from the injectors, unbolt the injector cover on the throttle body, remove the injectors and replace the orings around the injectors.

1990 c1500 350 5.7l TBI wont start sometimes. Fuel pump pressurizes, and oil pressure guage fluctuates massively. Then when you try to start it, it cranks but wont fire. no gas is getting to the carb....


If you pull the aircleaner off and watch the throttle body injectors they dont have anything coming out?
Double check the map sensor and the throttle position sensor?
Computer? I wonder if a wire to the computer has shorted out to ground.

The blazer is a 4.3 vortech. the fuel is going into the fuel rail but is failing getting in the throttle body. so what could be the problem


Fuel does not go into the throttle body on that engine. nThe throttle body is for air intake only. Fuel goes to six individule injectors via the fuel rail. Check for correct fuel pressure at the shchrader valve on the fuel rail. Correct pressure is 55 to 61 PSI. Anything less indicates a bad pump and possible dirty fuel filter.

ok, well as for the relay, yes there is one in your under hood fuse box....or inside the drivers door...but if you don't hear the pump, fear the worst, it may be dead.....happens ALOT.....check and change the relay, about $10, then if nothing, time for a new pump.

1990 full size blazer starts fine idles then dies


sounds real easy either a bad idle air control solenoid or more likley a blown throttle body gasket. to test fro a blown gasket, with engine running and cool spray carb cleaner or brake cleaner around base of tb were it bolts to intake. when it hits the bad area, should idle down and be normal for a second or 2. iac is possible,try this first since its so common and let me know

I need a diagram of my fuel injected 350 (its in my 1990 blazer), i need to figure out where and what the TPS looks like!!


Go buy one then look at your throttle body and find the part that looks like what you just brought. Its easy to install it has two small screws attached on the side of what used to be a carbuertor it is now called the throttle body in the middle of your engine,its usually on the drivers side of the throttle body.And it has a small wire harness that plugs into another harness.
