The fuel pump relay on 1986 Chevy Elcamino 4.3 TBI is in the Fuel Injection Tank.
I would start at the fuel pump if it is getting fire and will only run with fuel squirted in throttle body i would see if your fuel pump is working before i tore into it i would try the relay .
Try the fuel pump relay.
Check the fuel pressure but it's most likely the fuel pump.
Bad fuel? Bad fuel pump? Bad relay?
The fuel pump relay is located in the back of the glove compartment. Take all the junk out of the glove compartment and you will see a removable door that says "relay center".
There is no such thing as a TBI carburetor - it's either one or the other. TBI stands for Throttle Body Injection. It may look like a carburetor but there is an injected mounted inside the body. If you have no fuel it may be a bad fuel pump, blown fuel pump fuse of bad fuel pump relay. The filter may even be clogged.
fuse link wire on 1983 crown Victoria that goes to fuel pump was getting hot with ignition switch off?
on TBI cars, it is next to the AC clutch, on the fenderwell, on MFI, it is in the fuse box in the engine compartment.
do you have TBI ?
look at fuel pump, fuel filter, and fuel pump relay. If it has sat for long time, may have clogged lines. If you check relay, and that is good, look at pump. If pump is good, look at lines. If lines are good, look at fuel dispursing system, (Carb,TPI, TBI, etc) If fuel is going to all places, look at spark. Pull plugs and see if they are clean. May need to search for photos of dirty spark plugs
Yes it does. But you can not run a mechanical pump on a fuel injected engine. It will not pump enough fuel to run the engine.
check the automatic shut down relay on the inner fender. it will shut off spark and fuel when bad.
On the fuel rail on TPI, LT1 and on the throttle body if it's TBI.
Its not a good idea cause this will have more pressure., the tbi its a low pressure compare to the iroc -z tpi
i have a 96 s10 blazer 4.3vortec and the fuel pump relay is in the glove box, at the back left corner behind a panel, and the pressure regulator, depending on what kind of 4.3 you have how hard it will b to get at, is at the back of the injector housing witch is under the upper pleum( not sure if that`s spelled wright) witch is right on the top of the motor in the middle and if its a TBI unit its in the rear left corner of tbi housing
You didn't say if the fuel pump runs. If you turn the key to the 'on', not 'start', position after being 'off' for a minute, you should hear the fuel pump (in the tank) hum/prime for a few seconds and then shut off. This lets you know that your fuel pump is working and the fuel pump relay is at least partially working. If you don't hear the fuel pump run - check the fuel pump fuse, the fuel pump relay and the fuel pump. If you can hear the fuel pump run - If you hit 'start', and the engine runs for a few seconds, then dies, check the fuel pump relay (usually under a plastic cover under the hood at the firewall), the oil pressure switch (mounted on an extended pipe fitting extending up from the back of the block just under the distibutor), and the fuel filter. If the engine does not fire at all, check the injector fuses.
vacuum leak or fuel pump Randy
Same as any 4.3 S10 tbi fuel pump. All 1985 S10 2.5 motors should be fuel injected.
yes, yes it does no, its the crappy tbi systems. tbi stands for THROTTLE BODY INJECTION! it has fuel injectors and has to be treated as such. it is not carbureted.
400 gph, 45 psi
The fuel pump has no injectors: But there are two fuel injectors that set on the top of the TBI ( THIS LOOKS LIKE A CARBURETOR) but its not. They spray fuel into the intake. I think that's what you are asking.
Those are the wires that relay the information from the ECM / Engine control module to the fuel injectors so they will deliver fuel to the engine as needed.
