1997 GMC Sierra - Page 3 - Answered Questions & Fixed issues

you can unbolt those 2 15mm nuts to move steering column a little but usually I just fight with it great design aint it

theres a lot to it ,did you try autozone library its all free and no spam

If the starter engages when the clutch is pressed in, it probably has something wiring/connected wrong or a short in the wiring or other related components.

CAUTION - Be careful when using volatile fluids like starter fluid in the open as they are flammable and may start a fire; having a fire exstinguisher present is a good idea. Pull back a small part of the boot just in front of the throttle body, open the throttle all the way up and spray about 3 seconds of starter fluid inside the manifold. Push the boot back in place and attempt to start it. If it starts or attempts to start but shuts back off, it has fuel supply issues which could be the injectors, wiring, the ecm, the fuel pump or other related electronics.

I'd get a can of easy start or equivalent and see if it runs then, if so and u say u got fuel pressure it can only be a couple of things really 1 crank position sensor cam position sensor rail pressure sensor if it has 1 or ecu fault

You may want to check the ignition module or the coil pack(s) for the spark issue. How are you checking for spark? The parts house has a very cheap tool to check for spark. It connects to the plug wire and the other end connects to the plug which does not have to be removed from the engine. Have someone turn the engine over and the clear window will register a light if you have spark. You may not have fuel pressure because you cannot start the truck. I am assuming with no spark you do not have a running engine, which may be causing a no fuel pressure issue. Do you have a mechanical fuel pump or an electric? Fuel pressure issue can be figured based on the last question I posed to you.Hopefully answering the questions I am asking and the directions towards spark issues will fix your problem.

check the front transfer case, if that goes it will act like the transmission has gone

97 has 4l60 and in 98 some switched to 4l60-e.. which has shift solenoids.. all electric.. the connector on the side will tell you if it's the same or not. A 4l60-e won't shift if the truck takes the non-electric version..

it should be in the fuse box under the hood

see if you can find another steering coloumn from a junk yard, it will be cheaper than replacing the broken piece(s)

Had same problem with a Yukon. Turned out to be a bad fuel pump (Won't show codes.) When cold ran fine, heated up, no pressure. Would start after sitting for about 1/2 hour. When engine dies on you check for fuel pressure under the hood.

do you have head lights if so have starter checked

I would check the ground wire on the engine.

Could be the syncrnizer

when the problem occur keep ignition key on engine stop. with a test light find out if fuses have all current if not might be ignition switch defect

You may need to replace the external speed sensor switch located on the back of transmission next to the tail shaft. It runs about $26.00 and take less than 10 minutes to replace.
