i would start by investigating the fuse box for a possible blown fuse.also double check the wiring connector is fully seated on the part you have replaced

your going to have to readjust your ignition switch which is mounted on your steering column below the dash. there will be a rod that goes up inside it.

When you turn ignition key from OFF to RUN (engine not running), you should hear the fuel pump run for a few seconds and then shut off.

Best to check fuel pressure to be certain.

scan diagnostic codes for more insight and clear them. possible crankshaft position sensor or camshaft position sensor issue. Good luck!

1998 Chevrolet... | Answered on Oct 28, 2019

probably the camshaft position sensor is faulty. scan the diagnostic trouble codes for more insight into the cause of the problem.

Chevrolet Blazer... | Answered on Oct 28, 2019

I would agree with that assumption. your vehicle starts in 1st automatically. the vehicle speed sensor (VSS) tells the ECM how fast your vehicle is travelling and initiates the shift patterns at certain speeds and rpm's.

check and test the crankshaft position sensor and also the camshaft position sensor. Have a local autoparts store scan the dtc or diagnostic troubleshooting codes. this will you give yo a better idea of whats causing the issue. Also clear all dtc's and drive vehicle until check engine light comes back on. recheck codes. but i will almost bet the bank its going to be one of those sensors. also oil leaks will do a number on the wiring connectors. possibly a simple cleaning of the wiring connectors will solve the issue too

this is because its not fully shifting back into 2 Hi. make sure vehicle is in neutral and idling, push the 4 Low button listen for a shifting sound or whirring noise. then push 2 Hi button. it flashes while it is attempting to shift you should hear a shifting clunk or whirring noise, then the light will stay lit. after shifting from 2 wheel drive to 4 wheel drive shift into reverse before selecting drive on the column. the rpm going so high is because your vehicle is still in 4 wheel drive. the low gearing results in high rpm. if it does not shift into 2 wheel drive : there is a shift actuator on the transfer case, check the cable connected to it. this cable is connected to the vacuum control pump deal that controls you cruise control. this pump is located directly under the battery box. the plate the battery sits on must be removed in order to see it. check any wiring there and check for vacuum leaks in the lines connected to it . this pump actually pulls on the cable going to the shift actuator. check that the cable is attached and the baffle on the pump is moving. you can manually pull the cable by hand, while having an assistant operate the buttons inside the cab. this will release the actuator in the transfer case allowing the transfer case to shift properly. basically its a locking mechanism, locking the transfer case in the selected gear range. it must actuate in order to complete the shift

The security, antitheft or lock picture/icon is a visual indication that something in the car's antitheft system is failing. In most GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you put your key in the ignition, there begins a constant line of communication between your key's security chip or transponder, to the ignition's lock cylinder, and then to the car's TDM (Theft Deterrent Module). These 3 parts are in CONSTANT communication. If the key is in the ignition, then these parts are sending signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, the car misinterprets this as an attempt at theft and goes into antitheft mode. The car thinks its being stolen or hotwired because it is not getting that signal from YOUR specific key. This is why the security light turns on and shuts down your vehicle. This link explains it pretty well.

There is no replaceable fog lamp relay. It's built into the digital instrument panel junction box (IP) and switches power using an intelligent power switch (power transistor) that's soldered to the board.
When you turn on fog lamps the body control module sees the signal from the fog lamp switch. It sends a digital signal to the IP which tells the IPS to power the fog lights. You need to use a pro scan tool to see if the Body control module is receiving the fog lamp request and then see the IP is receiving the command to switch on fog lamps.

{: ) If the airbag light goes off after that 7 blinks (some are 6 or 8), that will be normal. The airbag module will blink the airbag warning light on the cluster while performing self-test during initial start-ups. After the self-test and the airbag module did not detect any fault within the airbag system, it will turn the warning light off. If the airbag warning light continuously blink or stayed lit after the expected elapse time, then there is really a concern and you need to double check the airbag system with a scan tool.

If the rest of your lights are OK, there may be a dead spot on the dash dimmer control (near the headlight switch). Cycle the control a few times to see if that fixes it. Otherwise, check the fuses at the left end of the dash.

Might not have enough antifreeze or can fix by perge air out, or one more thing try flushing the heater core.

If one of the mounts for the headrest has a push button you push to adjust it up or down, then the other mount will have a pinhole on the inner side. It is big enough to insert a small Allen wrench. Push it inwards to release that latch and work the headrest upwards, pressing both latches as you go.

Probably not the column, it is probably the PASSLOCK system. If I remember right, the blazer/ Jimmy were a bit special. If you have a stereo shop close by that installs remote start systems, give them a call.
