Remote Start Problem......Any Suggestions?

[Jmacartney]

I bought a 2002 f250 7.3 and it had a Viper Alarm / Remote Start.
Problem is it attempts to start but never kicks over. I took it to a shop and they said it has a 15 sec. delay for the GP's. Also he said the crank time was set at .8 seconds.

First visit they said crank time needed to be increased so he put it to a second.

Worked at shop, not when I got home and cooled down.

Second trip they said crank time needed to be increased so he put it to 1.4 sec.

Same thing, worked at shop but not at home after sitting a few hours.

Temps are 30's to 40's. I'm tired of back and forth to shop, can anyone help?


Thanks
John

it should read the gp or the delay should be a lot longer
i am on my second diesel with a remote start and it has to be under 10 degrees for the car not to start with the remote
if it is plugged in it will start at -13(tried it a month ago)

still seems the start time is not long enough, only a second? in 80 degree weather takes longer for either one of mine to start up, much less the cold weather we are having now.

Have you checked to see if it is waiting for everything to kick on before it attempts to start? If it isn't giving time for the pump etc to kick on I think you are going to have problems. If I am next to mine and hit it I can hear things kicking on before it attempts to crank it. Mine I think it set at 10 sec wait and I need to get the book out and up that as once in awhile it won't crank over. And I am thinking it is because all the components have not had time to kick on. Also will start playing with the crank time as it could be that.

Is it an older alarm? Must not have a tach wire?

[Jmacartney]

The wait to start is set to 15 seconds so everything turns of for 15 seconds before trying to start.

The shop told me that the tach wire on these trucks has a "dirty signal" and is not gonna read it.

No it's a current model Viper 5901 or something like that

Yeah I didn't use a tach wire on mine. I think I am going to change the wait to start to 20 sec and increase the crank time and see if that fixes it. It only does it fairly infrequently.

Gotcha, not sure if I should tell the shop to try the tach even though from their experience they say it wont work.

I am going to go back in on mine and clean up the wires length wise etc so it is cleaner maybe I will try hooking up the tach wire at that time and see what it does.
