Does a 1996 chevy s10 pickup 4.3 vortec have a saftey cut off that will stop the fuel from getting into the spider injectors


Sorry there is no safety valve or switch. Only Ford products use an inertia switch.
Have you checked for power and ground at the injector connector ?

no fuel? only means a clogged fuel filter, a bad fuel pump relay, or faulty fuel pump. Starter switch sometimes but rarely occur, but worth checking if nothing else fixes your problem.

1999 gmc suburban 5.7 vortec hard starting only when cold


The original "poppet" style fuel injectors used in these engines were notorious for causing hard starting/misfire issues on a cold engine. GM has since redesigned the injector "spider" that works much better than the original. Not saying that's what's wrong with your engine, but it is common on them. :)

Using to much fuel and running rough


How about the spider injector that might be the reason your vehicle is running rough and using up tp much fuel. The fuel regulator is part of the spider injector and it costs about $40. or $ 50. but if the injectors are bad then you will have to replace the spider injector, which will cost you $200. or less. From my own experience dont jujust change the fuel regulator and then have to buy the spider injector. It is best to make sure that it is not the injectors also. The fuel regulator is know to go bad on 95 GMC Jimmy believe me I have had to replace many other parts because of the spider injector.

Good luck

My 2000 Chevy S-10 with a 4.3 vortec is hard to start since I changed the intake gasket. Once started it runs great. Whats the problem.


which one did you change? upper or lower? or both?
the spider injection sys. is a piece of you know what. and I hate it as much as you do. it takes 55-65 psi of fuel pressure to fire those injector popets. If you have to take off the upper intake again, replace the regulater on the spider assy. since your in there. and look for strong spark at the plug, the type of spark that jumps at ya and bites you when your not lookin.

Just had to replace the fuel injector spider at 82,000 mi. because 1 of 6 injectors failed. this was a part that cost more than $400.00 plus installation. insane engineering that cost me , the consumer ,...


YOU HAVE CPI ( CENTRIAL PORT INJECTION ) TO CHANGE YOU NEED TO REMOVE UPPER INTAKE AND A LOT OF PARTS TO GET AT INJECTOR, NOT AN EASY REPAIR. INJECTOR SPINS IN HOUSING TO FEED ALL POPET VALVES (SPIDER LEGS) TO BRING FUEL TO CYLINDERS. USE LUCAS FUEL TREATMENT TO CLEAN AND LUB SYSTEM INCLUDING FUEL PUMP TO INCREASE LIFE OF SYSTEM.

What are spider injectors and how much are they


The term "spider injectors" stems from the Vortec Series Engine's fuel injection system. Unlike fuel injectors that are installed individually commonly used in engines, this one piece molded plastic web body which all 6 or 8 injectors are permantly attached(94-96), when looked at resembles a look of a spider. est. cost $350-$450. In 97 on up, GM changed from the fixed injector (If one injector goes bad you need to change the whole or all injectors) to being able to individually change each injector. est cost $50-$150 ea.

1996 Chevy 1500


OK first pushing the "gas" all the way down does nothing except when theTPS throttle psoition sensor is all the way open it shuts off the fuel injectors and this is called CLEAR FLOOD. When the truck does start is there a lot of thick black smoke?
The most common proble with the Vortec engineis the "spider" assembly under the plastic intake plenem. the fuel is delivered to the injector assembly the injectors are actually "poppets" on the end of plastic tubing that are fed through a fuel distributor assembly the fuel tubes often fail and get brittle and leak causing a righ condition which is why you need to hold the gas down to the floor. you are going to need to change the "spider " assembly and the fuel pressure regulator at the same time. this is your problem its so so common to the vortec engine. Now GM is the only place you should be trying to get these parts aftermarket will not work as well an could cause a fire. Gm will come with all the necessary parts to install it ONCE, and go ahead and buy intake plenem gaskets at the Gm Supply to while you are there Last I knew the "spider" and fuel presssure regulator were about $550.00 here in Seattle plus Labor to install
Hope this helps if you like this information please give me a fixya Rating I have personally changed about 100 spiders in the 14 years I owned my diagnostic repair facility here in Seattle
