20 Most Recent 1999 Chevrolet Tahoe Questions & Answers

I never had this problem with my truck but it sounds like it could be a bad connection signal from the new switch and the computer box that's causing the security light to flash. I know that switch has to be connecting properly in the steering column or it can give off a bad signal. it could also be a bad new switch

It is probably the TPS(Throttle Position Sensor) or the IAC( Idle Air Control Valve)
They are not very expensive, I buy mine from AutoZone. Not always but usually they will throw a check engine light. If so let A/Z put their machine on it, that should help pin point which one it is. Just thought of something else, if your is on the passengers side it could be the EGR Valve Selinoid. Hope this helps you.

I think that fuel pressure may be too high - the injectors work over a vary narrow pressure range. The regulator output may be blocked, or the pressure may just be too high for the injectors. I would start by replacing the regulator.

You could have a plug wire periodically leaking voltage to ground if the wiring is not properly installed, or a problem with your distributor/rotor, but could also be caused by many other sensors (such as a faulty crankshaft sensor) or problems with your fuel system (filter, regulator, etc.).
I would check these plug wires carefully for contact with the engine and good connections at the distributor/plugs, and also add a good quality fuel system cleaner (gas tank additive) before going on with troubleshooting.

Automatic or manual transmission ? tumbler sends voltage ??? What tumbler ? Ignition switch ,when it start position sends B+ voltage to the crank fuse in the insturment panel fuse box ,from there it goes transmission range switch,if in park or neutral it then goes through the relay pin 86 at the relay socket base . With the key in start you should see B+ voltage there . If not ,try moving the gear selector to neutral . if you still don't see B+ voltage , find the trans .range switch an check it.

The usual procedure is to disconnect the electrical connectors, remove the fuel rail nuts, pull the rail up, and then replace the injectors. Is this not the procedure you used? We need to know more about the circumstances to help you.
