    Ignition problem on 02 Transam, Please help!

    I am having an issue with getting my 02 TA WS6 to start when its cold. Its a stock LS1/6 speed. What its doing is when I turn the key to start, it will do nothing. Depending on how cold it is, I can keep it on start for 10 seconds and then it will fire up. This usually only happens during the cold mornings. During the day, it fires up just fine. I have replaced the battery and starter relay. Could it be the starter itself or some other ignition point? Its only been going on for the last 2 months and has just over 75K miles. Any help would be greatly appreciated. Thanks

    Could be the Ignition relay. I had that problem a few years ago, swapped out the Ign relay and it was back to normal. When it does it again switch it out with one that is the same (fan relay, horn ect.) and see if it starts.

    Replaced the ignition relay last night and fired up fine but was warmer temperature outside. Started it this morning and still will not start right away. Still has the delay. Any other ideas? Thanks

    Fuel pump? Maybe it is getting weak. Put a fuel pressure tester on the fuel rail and see what you get. Should be around 60psi wub key on.

    In addition the fuel pressure should hold for several seconds at that pressure. If you start seeing it drop down after 10-15 seconds post it.

    My fuel pressure falls off after energizing the ignition unless the engine is started on our car, then it jumps right back up. However, it hasn't caused any starting problems. On our '07 Suburban, it would crank and not start -- that was the fuel pump on its way out and after replacement we have had no issues. If I understand the original post, the starter isn't kicking in when the key is turned. Am I off on this?

    Your right Jeff, I think he is having a no crank issue, don't know why i was thinking fuel pump.

    Swapping out relays is still a good idea as that could easily be the issue.

    I swapped out both the starter and ignition relay and put a piece of foam under the cover to hold them down firmer and still no crank. Its about 30 degrees this morning and I had to hold it on start for about 10 seconds and then it finally cranked and started. Like I said, it only does this in the morning when its cold. After I let it warm up in the morning, I can shut it off and restart with no problems. Any other thoughts please??

    Check the wiring connections at the starter/solenoid and make sure they are tight. If possible, you could check voltage at the solenoid while someone attempts to start the car. If you have voltage, and the starter doesn't work, you have a faulty starter or solenoid.

    Examine this Ignition relay and also Substitute this ignition relay

    you might to get underneath the car in the morning and using a voltmeter or test light check for 12v at the wire that comes from the starter relay(signals the starter solenoid to close) like Knight said. You will need someone to get inside the car and turn the ignition key to start. If you have
    12v then check battery cable connection. Make sure they are all clean. It is possible the starter solenoid is getting weak.

    If you don't have 12v then you need to start checking the wiring, relay or ignition switch. Most time is the relay that is bad like the rest of the guys had mentioned.

    Thanks for the replies. I will be getting under the car soon to check the wiring going to the starter. I will post my findings. Thanks
