    Default Feelin' Your Pain

    I printed out the L98 start sequence info when I was working on mine. It doesn't say a thing about the injector issue. When you run out of possibilities from the start sequence, try the disconnecting individual injectors test and see if she starts and runs. Then I would check the connectors and then the wires for shorts.

    Victory will be sweet when you figure this out!

    Default Any Progress?

    Any news? Did you figure it out? Did you check the resistance of the cold start injector? Did you check the injector wiring harness? If you figured it out, let us know.

    I keep reading this and can't figure out why this don't run.. So. I have only one reason that it won't run, You have a BAD TIMING CHAIN, Its the only thing that would do what it is doing assuming all the other parts replaced are good. I would pull the cover and check it out.

    You are 100 per cent correct. Timing chain was defective due to plastic gear on the cam shaft. I found this by watching the rotor jumping while it was rotating, mystery solved. For me this has been a trial on my patience, mechanical and electrical skills. Not to mention one of the strangest problems I have ever come accross.

    Thank you all for your imput and encourgement especially Ron Kane from Ind.and Jon from Georgia.

    I had to hear it running before I could post the final results.

    Default YEEEHAAAAA!!!!

    Congratulations! Thanks for sharing the final solution. It may have been a trial on your patience but your patience paid off. You now have a running torque monster L98. You've learned tons about its operation and you've checked or replaced a lot of stuff that should now not give you any problems. You've also probably helped someone else now or in the furture by sharing the experience. Enjoy your FORMER basket case!
