Question about 1990 GMC Sierra

4 Answers

1990 GMC Sierra 1500 will not start it just CLICKS

This is my sons truck and NOT the first time with this issue. We have
1. replaced the Alternator a couple of months ago.
2. Load tested the battery today. All good
3. Removed the starter..last time and they said all good.

THEN, upon return, last time,a small wire with a plug was found loose and or not connected to some type of port on the bottom of the engine . The truck started. Now once again CLICK.And my son is not very mechanically inclined. I would hate to have him pull the starter AGAIN only to hear nothing is wrong with it.

HELP!! Thanks.

    We pulled the starter and just as I thought the tested it THREE times and say its OK. Reinstalled it with a NEW positive cable from the battery and CLICK CLICK. All the wires seem fine. Is there any relay or other issue we could check?

Make sure the electrical wiring is not corroded or loose its an old ride and the network ages. the starter maybe old check it over or bring to discount for meter test-free electric motors go bad -insulation it hard to find good mechanics thats why there is 2nd and 3rd opinions. many books in library under 629 auto

The click is your starer solinoid.Check the wires are clean and tight from the battery and alternator.Also clean and tighten the ground wire from the battery to the engine.Good luck.

I just went through the same thing and it turned out to be the negative battery cable. It looked fine and was clean, but was screwed up internally, no issues since I replaced it.

Check the starter ring for missing teeth where the starter connects. sorry though you have to take the starter off and if thats the reason you have to pull the moter and turn the starter ring around

Smoke at start up


The Stop Leak products might work short term but some of the additives can cook off and become varnish in a hot engine and also whatever swells the seals will harden them over time.
This is the procedure to replace the valve seals with the engine in the truck and there is minimal tear down required
remove the valve covers and spark plugs.
get a compression tester , remove the valve core.
install the compression tester into the spark plug hole. connect the air hose to it.
use a valve spring tool to compress the valve spring.
Use a pocket magnet to remove the keepers.
remove the spring and install the valve seal.
This would be a nice time to upgrade the valve springs.
Make sure you do only one cylinder at a time with air connected to the cylinder you are working on.
This keeps the valves from falling down into the cylinder

However i also have a 1990 chevy pickup with a 5.7 liter in it and it has given a puff when you start it for several years and it uses little oil between changes so unless it consumes vast amounts of oil or has problems with passing an emissions test (If applicable) your money will be much better spent elsewhere.
hope this helps.....Good Luck!
