A 94 doesnt have a fuel "spider" it is still throttle body injected
weak fuel pump or fuel lines leaking under intake penilum or fuel regulator or injection unit (spider itself) and or plugged injector tubes. (94 safari 4.3 CPI injection)
The 95 models did not have the spider on them. It was a TBI / Throttle body injection system. If your engine is a vortec, Then no it can't be cleaned.
To my knowlege the spider fuel injector system came out in the 96 models. 1995 still had the throttle body injection.
1992 spider 4.3 was equipped with CPI ( Central Port Fuel Injection ). This system had one centrally located fuel injector distribute fuel to six hoses each with a poppet valve to each of the intake ports.
You don't. You can remove pump and pre-mix the gas.
The fuel injection system that resembles a "spider" came out in the 1996 S10 models. The 1995 still had the TFI (Throttle Body Injection) system. If you are looking for the fuel pump relay for the 1995 S10 series, look in the glove compartment, you will see a access door marked "relays". The fuel pump relay would be the first one on the left side.
I had something similar; did what you did; plus replaced fuel pump, egr, and fuel filter. It ended up being the spider fuel injection system.
If you have the central injection system, you regulator is inside the plenum, next to the spider assembly. Takes about 20 minutes to get to it.
an injection under the skin is called a sucutaneous injection.
If you cannot get gas to the fuel injection system, you may have a clog. You can have the system looked at and flushed out and take it from there.
Plunger stroke is the speed on the engine. This is the injection system on a diesel.
Yes all new cars are injection
