Security is the problem.. are you using the same old key you always have ? using a cut key or another key will set this off..

Yes it screws in on right side of tramission and you will need a 7/8 inch deep socket to remove it. You may be able to clean the old one once it is removed. There is a little ball thatgets dirty and may you can get by with cleaning it. Good Luck. Ed

SOURCE: 98 s10 cranks but wont start. Checked for spark and fuel press,

Yes It does. There are (or should be) toggle switches to reset security alarm. However, the ignition hot lead passes through the security relay contacts. This relay may be the culprit, in that if it does not pull when ignition key is turned; The start relay will not pull disabling fuel pump and spark.

SOURCE: 1987 s10 chevy truck 4x4 not engaging

By the way, if that happens again (Same thing happened to me) It was inside the front diff. That vacuum actuator that sits on the passenger side that has a vacuum hose going up to it has a built in cable that plugs into the front diff. There are little springs that go bad and there is no tension on the cable. It retracts but doesn't engage the axle.

It's 3 bolts, then pry it open just enough to get access to the spring that holds the cable together. ;) That's how I fixed my problem permanently

Chevy s10 wont start


Just a thought, it could be the antitheft system "passlock" this can turn your injectors off if not functioning correctly. (that's the antitheft, can't run with no injectors). You would see a light on the dash that says SECURITY or ANTITHEFT. This link explains.

I have a 1998 s10 chevy pu. 2.2. the security system has the fuel shut off. it wants to start right @ first then it just turns over. plenty of fire and i can smell fuel. what sensor is out u rekon? no chip...


if the security light is on, that means the system is failing and shutting the fuel off to the injectors. If it doesn't have a chip, it probably runs off the transponder in the plastic part of the key. This is very common on GM vehicles. Check out this link for info and opinions to fix this yourself. http://vatspasslockpasskeysecurityhelp.yolasite.com/

1983 s10 p.u. wont let fuel out of injector ive replaced fuel pump injector tps cpu


It sounds like that the security system has encountered a problem...Did you notice a light coming on the dash saying security? Your ignition ,all though no chip in key,references to a security module...what this does is tell the computer that the same key is being used to start vehicle...The condition that would come from this problem would be a crank with a know start condition....the security system actually shuts down the injectors if reference signal isnt recognized.POST IF THIS IS THE CONDITION YOU ARE EXPERIENCING>>>

Fuel pressure regulator. It regulates the fuel pressure you receive going to the injectors. All the injectors would not be bad, so you have to take a step back to the next component, which should be the regulator.

Hey have you recently changed your head unit. I have a 2000 s10 2.2 and i recently hardwired my pioneer 4000ub head unit and the security light came on upon not starting. every time you try to start the car while the security light is on it will add 10 minutes onto your time. For the security light not to come on you need to check your wiring. just remember dont keep trying becuase it wont work!!! find the problem and fix it.
