94 GMC Yukon (No Spark)

My 94 GMC Yukon will not start. It appears as though I have not spark.
I have replaced the ignition coil, dist. cap, rotor, dist. coil, and it still will not start.
Please help.

    I checked them days ago. No codes present.

  • jonesfam5 Jun 20, 2009

    I believe that I have the distributor in correctly. Still no change.


    The only thing that I may need to add is that the vehicle sat for a month and half and the battery was dead. I am having to jump start it now and it has not been a problem in the past when the same situation has occured.

Check your spark plugs and see if they need to be replaced. Check the gap on the spark plug. You may have low compression, timing belt or chain should be checked as well. Check the computer system in your car. Is your check engine light on? Maybe your crank sensor is not working properly. Try these and if not get back to me and we'll try more possibilities.

You mentioned that it appeared that you were not getting spark but what process did you use to see if you were getting spark or not?

    Have used a DMM to check ohms and after turning it over pulled plugs and they where wet with fuel.

Were is the ignition module located on a 1999 gmc Yukon


Instead of spending money on parts, you should get a book and troubleshoot the circuit. It could be the pickup or the module in the distributor, or other electronic components.

1997 5.7ltr gm truck...wont start. Replaced fuel pump, and relay. Has a carbon build up in the throttle body. Turns over/wont start


check for spark if there is no fuel coming out of injectors you can borrow noid lights from orielies auto parts check the injectors for pulse width if you have no pulse your computer is bad if vyou have no spark remove dist ributer cap and see if rotor turns while cranking if it does check for spark between coil and dist if no spark you more then likely have a bad ignition module

2000 Yukon denali having trouble starting. Sounds flooded. After it sits awhile it will start. Replaced fuel pump. Still having problem. Security light is on. Replaced ignition switch. Please advise.


If it is flooding,fuel is not the problem.Sorry you did a pump already.You need to check spark and air,I would start with spark.Check your plugs for spark.If they all spark normal,that also means the ignition coil is good.That leaves air.Check the filter and intake hose for leaks,holes,etc.I would guess spark,but you never know what you'll find.If you are not 100% sure how to check spark,sounds like you probably do though,just comment on this post and I get an auto email linked to here and tell you the best method.Good luck!

Three days ago i had to remove the intake manifold on my 1994 gmc yukon 5.7 liter had to remove throttle body and dist have replaced along with dist cap, rotor and coil the truck ran fine but now won't...


Check to make sure the coil wire is secured to the distributor cap and rotor.
Also check that the rotor is not cracked (even if new) and that the spark plugs are not loose - wires are not loose, frayed etc.
Also, make sure all connections on the battery, ground at chassi, and positive on starter are in good repair as well.
Please, let me know if you need further assistance.

2003 gmc yukon xl does not start. tries to turn over but doesnt...battery good and has fuel. what wrong


the H.E.I distributors have a problem with the modules blowing . check you have power in the main power wire to the dist with key on if there is then my guess the module blew / pop the cap off the dist ,remove the rotor , you'll see a half moon looking flat electric box with 2 wires going in ea side change that part and try it there's also a pickup coil /if you can make sure no wires are broken on the pickup coil or change it .hope that helps . sounds like you lost spark and that would be my first guess / the module went :)

Cranks but will not start.


Ignition coil or distributor cap. Not knowing the Avenger I couldn't tell you where to find either but follow the HT leads from your plugs and you should find them. If you aren't getting a spark on any plug then the perp is your ignition coil and it'll need replacing, if you're getting a spark on some then it's the dist cap, check the contacts and give them a clean and see what happens. F.Y.I. the dist cap is the first thing back up the line from your plugs with all the HT leads going in, and the ignition coil is after the dist cap.
