Could be fuel or spark, or even a poor cylinder. With a spark tester, look at spark on all cylinders, do a compression test to verify good compression. (Valve problem, or jump timing at the timing chain)
You should check fuel pressure before changing a pump. If all of this looks good, a noid light at the injector (s) will tell you if the computer is firing the injectors properly.
If you can get it to idle, remove a spark plug wire, one at a time, if it runs worse, that cylinder is working, if it has no change, that cylinder has a spark or fuel issue, for that cylinder.

Is the fuel pump located inside the tank on a 1989?


dont go replacing everything...thats gonna get expensive real quick...especially that fuel pump. yep...the pump is inside the tank. stand out side your truck,and turn the key over,but not enough to start it. you should haer a whirring sound lasting about 2-3 secs. come from the back of the truck. this is the fuel pump powering up. if you dont hear it...then the pump is bad. if you do hear it, have a friend turn the key while you look at the carb/injectors to see if fuel is spraying thruthem,if it isnt....then you have a clogged fuel filter. BUT...b4 you do any of this...check your fuel pump relay and fuse to make sure they are good. a 10 cent fuse beats a 200 dollar pump any day.
keep me posted!!

Just changed fuel filter. Now having trouble starting. Then runs


What is the fuel pressure?. how many miles on the truck? has the pump been replaced before? one item to check first is the fuel pressure regulator. it may be under the engine cover on the drivers side. turn the eng off and remove the little vac line from the regulator. see if there is any fuel coming out of the nipple. if there is fuel, replace the fuel pressure regulator. it may take a while to leak fuel , but if it does, replace it.

Replace the fuel pump relay. And if your truck has dual tanks there's three fuel pumps, one in each tank and another secondary fuel pump.

check the fuel pump as well to see if you are getting the right amount of fuel if not the pump itself may run about 20 dollars or so , check timing as well just to see if your off if you have an advance on the distributor and if you go over 40 if it pops back up its the advance {had that problem once before }

Help w 1994 chevrolet truck


This injector set-up needs a specific fuel pressure supplied to the fuel rail to even start, much less run properly. The fuel pump is immersed in fuel inside the gas tank to keep it cool and not burn up. Running the fuel level low causes more heat in the pump and interuptions in proper fuel pressure. AC/Delco pumps have proven to be a reliable fix, the aftermarket pumps only last for a month or two sometimes. Check fuel pressure under the hood and power and ground to fuel pump at electrical harness at top of gas tank. This truck needs a fuel pump.
