Try this, remove the fuses for the RS and also remove the key from the bypass module. This will be like removing the entire system of the RS & module from the OEM wiring. Try to start the truck now, post your results.

Well I completely removed my remote start yesterday and re-installed everything....there is a 12v relay wire on my remote start that i hooked up to the 556u..i only tried it once but it let me start with the key right away instead of having to wait 5 seconds...i am going to hopefully finish install today....i did hook up both relays to the starter wires...hopefully all works! I tested out last nite and the my doors would not unlock...think maybe the quick splice didnt work on the wire...i will have to try again...everything else works though

I went to Audio Express yesterday and they found the problem and fixed it. I got an explanation from the installer, he said "the 555U has a green wire that neded to be tied to GREEN/ black on key cylinder". This fixed it....

I think this is the same thing the first response to this thread recommended.

He did not say that he did, and I asked him to tell me everything he did for the sole purpose of posting the fix here.

Update: I went to Audio Express yesterday where the alarm was installed and the salesmans response was "there's no way the alarm could be sausing that", he said "it must be the trucks ignition system." I explained to him that since the car started "fine" with the remote start that therefore the ignition must be working fine. Also, I showed him the print out of of the first four responses to this thread, and he literally "laughed", saying that the suggestions above were ridiculous.

I guess we're all comedians who know what the heck we're talking about ?!?! Glad to have made someone laugh at Audio Express. I hate it when " sales people " think they know it all about installations problems and what not ! Hard start when using key - Page 2 -- posted image. Any way, good to hear that you got the problem fixed at the installation place that you bought it from. Too bad they were dicks about it though in the first place.

OK Here is the deal with my problem...I have a Crimestopper CoolStart...I cannot use the (-) keysense wire because the latch output of the 556U and the status output wire from my remote start have to go on this. I cannot hook the green wire up from the 556u to this because it thinks there is always a key in it due to the fact that it is hooked to the remote start system all the time. On that ignition wiring harness though, there are two wires...that GREEN/ black one and another wire....does anyone know if the other wire is a (+) keysense wire since the GREEN/ black is a (-) keysense wire? If it is that I can just hook to that. Please help me!!

Question: when you originally did the install for the 556U, which of the wires did you use?

Here was what i thought was wrong with your original installation: In the 556U, the only wires most installations need is the 12v+ and the status wire. Theres also an IGNITION wire in the harness as well. Well, from personal experience, i connected that wire to the ignition in an explorer (that required a key bypass), and the truck had a hard time starting... about every 3rd try with the ignition key. But, it would start the first try w/ the R/S. So, make sure that the ignition wire isn't powered from your 556U. a way to check this would've been to unplug the cable that plugs into the 556.

What about keysense? just interrupt the wire. True, its a GREEN/ black (-) wire. connect 12v+ to pin 85, GREEN/ black keysense wire to pin 86. connect the R/S status output to pin 30, and the 556U's status to pin 87A. what will happen is, there'll be a connection between 87a and 30 (status outputs of both products) UNTIL a key is placed in the ignition. when that happens, the status output is broken between the two units, stopping the 556U from sending a code.
